CUTTING-EDGE TECHNOLOGIES

The advanced technology in MVG systems supports our customers in their drive to innovate. Our aim: to give you a sharper edge and faster ROI (Return on Investment). The speed and accuracy of our systems stems from two cutting-edge technologies: 1. MV-ScanTM Technology 2. Advanced Precision Electro-mechanical Technology

1/ MV-SCANTM TECHNOLOGY: FAST - ACCURATE - SMART MV-ScanTM Technology is integrated into all our multi-probe systems. With MV-ScanTM, an array of probes is electronically scanned, increasing measurement speed while also gaining in measurement accuracy. It’s also smart technology that allows for choices in configurations in order to limit mechanical movements.

Faster measurement time optimizes measurement facilities A major R&D investment, facilities are used more efficiently as faster measurements allow more antennas to be measured in a shorter amount of time. ROI is maximized.

Fast

Accurate

The need for faster measurement of antennas and radomes is a growing concern in the industry. Not only do our customers want to test significant numbers of beams at once, they want to test more frequently and in a short amount of time. Optimizing ROI is essential.

High levels of accuracy and repeatability remain an absolute necessity for the needs of increasingly complex testing. We are able to ensure measurement accuracy of our systems as a result of several complementary factors.

The electronic scanning of an array of ten to hundreds of probes using MV-ScanTM allows the measurement of a full cut in quasi-real time.

10

Faster measurement time quickens the overall antenna development process As you gain time in antenna testing and measurement, you gain time in the development of your new product.

Precise knowledge of our systems’ error budget Knowing the error budget is essential for predicting the accuracy and repeatability of a system. Each of our systems undergoes a validation process where the error budget is determined for reference during installation and maintenance.

Comparison studies  As a second measure in system validation, we perform comparison tests in different types of ranges (near-field, far-field, compact ranges, etc.). The results of these studies allow us to obtain the data necessary in fine tuning the accuracy and repeatability of our systems.

H-cut of the Aircraft Front Radar

Continuous probe calibration  All our systems are equipped with a reference channel that is connected to the same amplification unit as the measurement probes. This allows continuous drift compensation, thus ensuring measurement data accuracy over time. Reduction of mechanical movements  In most classical spherical single-probe measurement systems, the DUT (device under test) is rotated in azimuth from 0 to 360° and in elevation from 0 to 180° in front of a single, stationary probe to measure the field surrounding the device. MVG's spherical multi-probe systems limit CHAMBER mechanical movements by rotating only the DUT 180° in azimuth while the fields surrounding the device is simultaneously scanned by the multi-probe arrays.

The reduction of mechanical movements enables: • Improved measurement accuracy, especially for roll over azimuth measurements where multiple mechanical movements can be a source of disturbance • Increased measurement repeatability, reducing the risk of error which is an important factor in antenna optimization • Extended system life, as repeated movements can affect the reliability of mechanical parts

N-Probe Array Controller (N-PAC) 1

The N-Probe Array Controller is the heart of MVG's multi-probe advanced 4 It comprises the necessary components driving the measurement systems. system's equipment (motors, probe array, instrumentation…). This powerful and highly accurate 2instrumentation provides real-time acquisition and system management thanks to an embedded FPGA. This includes an IF receiver offering aMixer highUnit dynamic acquisition range (up to 110 dB) and asynchronous communication with several remote PCs. Its massively parallel architecture brings new possibilities into the monitoring 3 of complex measurement. The N-PAC comes with monitoring software to manually control the motors, select probes and visualize the pattern of the device under test in real time. All this via a touch screen PC or tablet.

Smart The use of probe-arrays reduces the number of probe/DUT positions necessary to complete a test. This results in fewer mechanical movements. In addition, we offer a choice of geometries as well as different types of arrays to allow you to attain the most efficient configuration. Mechanical movements are thus minimized and speed and accuracy are maximized. The right geometry for your application An array of probes can be integrated into different system architectures. • Spherical geometry (SG systems – SG 24, SG 32, SG 64, etc.): Tests any type of antenna. Necessary for OTA testing or for testing wide-beam and omni-directional antennas such as wireless devices. • Cylindrical geometry (StarLab, T-DualScan): For semi-directive antennas such as BTS antennas • Planar geometry (T-DualScan): For highly directive antennas such as phased arrays, satellites, communication antennas

Optimized positioning configurations  Various probe array and positioner configurations are possible depending on customer constraints and on the size of the object under test. • Stationary arch - the positioner rotates the object under test 180°. • Stationary or movable arch - the array can move in and out of the shielded anechoic chamber. The object under test rotates on a positioner or a turntable. • Linear probe array - the array is fixed to a frame scanner; it moves on one axis. • Movable arch - the array moves around the object under test. This innovative technique simplifies the measurement set-up for very large devices under test: the DUT remains stationary as the measurement array is displaced as required.


Unlimited scan resolution in both azimuth and elevation  Our multi-probe systems offer patented oversampling capabilities in order to achieve unlimited scan resolution. Oversampling is done by combining automated mechanical movements and the electronically scanned probe array.  The spacing between two probes of an array, for example 5.29° for the SG 64 is suitable for small antenna testing. For larger antennas, an additional mechanical rotation in elevation can complement the probe array azimuth scan. The positioning mast rotates in elevation, for instance ± 2.6° for the SG 64, in order to adjust the DUT to offset positions. This “fills in the gaps” and provides the possibility of unlimited sampling.

2/ ADVANCED PRECISION ELECTRO-MECHANICAL TECHNOLOGY Integrated in all our systems, this technology allows: • Real-time control of positioning sub-systems • Fast measurement with high speed linear motors • Increased accuracy of positioning systems and subsystems with the MV-CorTM correction table service

Real-Time Full Control of Positioning Sub-systems MVG positioner controllers offer real-time control of positioning subsystems up to 4 axes in parallel for use in near-field and far-field antenna measurement systems.

The linear motor drive system offers several important advantages over conventional drive systems: • No backlash • High acceleration • High motor force • Excellent mechanical dynamics; for very fast stepped-mode measurements • Continuous y-axis speed, up to 2 m/s for on-the-fly measurements

+

Combined with MV-Cor™ on-the-fly positioning error correction, linear motorization allows superb mechanical accuracy of the planar scanner while maintaining high measurement speed.

The implementation of these correction tables is a two-stage process: 1. The raw positioning accuracy of the axes is measured using a laser tracker. The data is then analyzed, processed, and a set of geometrical error correction maps are built and loaded into the controller using a proprietary MVG calibration tool (Mect™ software). 2. The correction algorithms are activated and the positioning measurement is repeated to verify that the required accuracy is achieved.

The MV-CorTM correction table service is a cost-effective solution to enhance range performance without replacing the entire positioning system. MV-CorTM ensures minimum range down-time.

MV-CorTM - Increased Accuracy Using MV-Cor™, the corrected accuracy of mechanical systems is given by the repeatability of the system, the accuracy of the independent calibration equipment (like a laser tracker), and the stability of the environment (foundation, temperature, etc.). This unique service increases the accuracy of positioning systems and subsystems (typical accuracy improvement is a factor of 2 or 3) by integrating geometrical error correction techniques into new or existing systems. MV-Cor™ uses continuous feedback correction, the only method that compensates for both position commands/ feedback and the variable gain measured by the control filter. Correction tables are loaded into the positioning controller.

For near-field passive measurements, a Vector Network Analyzer is used as the RF source/ receiver. The Control Unit drives the two positioning motors and the electronic scanning of the probe arrays. For OTA measurements, the tests are performed through the Radio

24

Communication Tester. The amplification unit amplifies the signal on transmission and reception channels according to the frequency bands. The Transfer Switching Unit is used to switch between the emission by AUT and the reception by AUT modes. The power and control unit supplies the power and drives the RF units.

The signal generated by the Radio Communication Tester is modified by the Spatial Channel Emulator that creates multi-path signals including delay dispersion, fast fading, path delays and Doppler shift. Those signals are then amplified by the amplification unit and transmitted simultaneously to different locations by probes. The probes can be used to represent the direct signal, multi-path signals or interferers, thus creating a specific RF propagation environment at the DUT position.

MV-CalTM PATENTED Quick Calibration Tool for MIMO Testing MIMO calibration requires that each channel have the same behavior in terms of group delay, amplitude and phase. Industry standards are being drafted to make calibration with a set of dipoles covering the frequency band of interest mandatory. The drawbacks are: • Dipoles are narrow band, so many dipoles must be used •  Dipoles are mono-polarized so that electric and magnetic dipoles must be used if dual polarized tests are to be performed • Each channel contains active elements that are time and temperature dependent, so that this calibration (which can take up to 2 hours each time) must be performed up to several times per day • This calibration does not calibrate the probe array itself (the radioelectric axis of each probe should still be calibrated for high quality testing)

MV-CalTM takes root in MVG's experience in multiprobe system calibration. It’s an automated, fast, and simple OTA MIMO Test System calibration solution. Two sets of coefficients are processed and stored: • The first set calibrates the RF equipment outside the anechoic chamber. It is measured quasi-instantenously and can be reassessed automatically as part as the measurement process. • The second set calibrates the probe array itself. Probe array calibration is the same whether you want to perform SISO or MIMO measurements. MVG has more than 10 years of expertise in probe array calibration. The MVG process ensures that each probe has the same amplitude, phase and polarization response. As the probe characteristics do not vary over short time periods, this calibration is generally necessary only once a year for high quality results. With MV-CalTM, both sets of coefficients are applied during the measurements. This removes the task of recalibration with a dipole or loop antenna, which normally takes a couple of hours. When associated with StarMIMO, the overall measurement time is drastically reduced.

Control Unit

SG 24 uses an Active Switching Unit to switch between antenna and OTA measurements. For antenna measurements, it uses a Vector Network Analyzer as the RF source/ receiver. The measurement speed can be up to 3 times faster depending on the VNA models used such as the Agilent PNA-X N5242A. The Control Unit drives the two positioning motors and the electronic scanning of the probe array. For OTA measurements, the tests are per40

formed through several different Radio Communication Testers. The AmpliďŹ cation Unit has RF ampliďŹ ers for each of the RX and TX channels. The probe selector unit uses a new multiplexing technique and inceases dynamic in the probe array by almost 20 dB at 6 GHz. For Wi-Fi and other protocols that use dedicated Radio Communication Testers, the Active Switching Unit has dedicated ports. This system will be compatible with the N-PAC in the near future.

The goal of the StarBot 4200 spherical in-situ near field test system is to characterize the on-board radar antennas located in the nose and tail of the aircraft. The StarBot 4200 is a portable, multi probe system composed of 61 dual polarized probes distributed over half an arch of 3.2 m internal diameter. One spherical dimension is measured by an electronic scanning of the 61 probes at a very high speed. The other dimension is obtained by a simple rotation of the arch around the first to last probe axis.

68

The probes are separated by 3째 (from 0 to 180째). Thus, there is no truncation in the dimension of the array. Even if the mechanical scanner is designed to allow a complete rotation of the arch over 360째, the angular coverage is limited by the aircraft. Measurements can be performed in CW or pulsed mode thanks to a network analyzer. An electronic module manages the interface with the radar system by generating the pulses necessary to control the radar.

The 6 axes enable flexible positioning so as to access antennas placed anywhere on an aircraft. The system is driven by a full remote control robotic system to facilitate displacements and positioning.

One spherical dimension is measured by an electronic scanning of the probes at a very high speed. The other dimension is obtained by a simple rotation of the arch around the first to last probe axis. The goniometric axis allows for oversampling. The aircraft itself is the only limitation to completing the 360째. Measurements can be performed in CW or pulsed mode thanks to a network analyser.

TRP is the total RF channel power radiated by a wireless terminal. It is calculated by integrating the measured Effective Isotropic Radiated Power (EIRP) data over the measurement sphere. The EIRP is measured every 15 degrees in both elevation and azimuth, at a minimum.

80

This accounts for a total of 1656 measurement points (23 elevations × 12 azimuths × 2 polarizations × 3 frequencies), with a typical measurement time of about 3 minutes (depending on the protocol and equipment).

TIS is a figure of merit for the overall radiated sensitivity of a wireless terminal. It is calculated as the integral of the measured Effective Isotropic Sensitivity (EIS) data over the measurement sphere. The EIS is measured every 30 degrees in both elevation and azimuth, at a minimum. This accounts for a total of 396 measurement points (11 elevations × 6 azimuths × 2 polarizations × 3 frequencies), with a typical measurement time of about 90 minutes (depending on the protocol and equipment).

The EIS is calculated by a search algorithm that finds the minimum power level radiated onto the DUT for which the error rate is lower than a specified limit. Typical 3D plot of total EIRP (EIRPtheta + EIRPphi )

To ensure the compliance of wireless devices, it is required to undertake comprehensive Assisted GPS OTA antenna measurements that meet the demands of the CTIA certification standards.

The incorporated software facilitates the measurement process by simplifying the user interface and providing a software wizard for the measurements required for CTIA certification.

MVG's multi-probe antenna measurement technology minimizes the mechanical movements required to test a device-under-test (DUT). When used in conjunction with an anechoic chamber and instrumentation, the system is compliant with the standards specified for CTIA certification of wireless devices.

The system performs a comprehensive set of measurements consistent with the CTIA certification standards. These include the characterization of antenna radiation pattern (C/N), linearization, sensitivity (peak, TIS, UHIS, and PIGS), as well as intermediate channel degradation (ICD). These tests ensure that interference from cellular communication across the band does not degrade the GPS performance of the wireless device.

Sensitivity Algorithms

SHORTER MEASUREMENT TIME MVG offers several methods to reduce the TIS measurement time. One method, the TIS based on the Rx level, uses the DUT receiver as a power meter with certain communication protocols (like GSM and WCDMA). From each measurement point on the measurement sphere, a constant power is radiated towards the DUT. The DUT receiver then reports back its received power level and the complete spherical set of power level data can be referenced to a single-point EIS measurement to determine the TIS.

Software SAM is the software interface for automated OTA performance testing with StarLab and SG measurement systems. It enables the measurements of both radiated power and sensitivity, supporting most of the common wireless communications protocols: GSM, GPRS, EDGE, CDMA2000, CDMA 1xRTT, CDMA 1xEVDO, WCDMA, HSDPA, HSPA, HSPA+, LTE TDD/FDD Wi-Fi 802.11 a/b/g/n, BLUETOOTH 802.15.1.2, PHS, TD-SCDMA, TD-HSDPA, (Contact us for an updated list).

CTIA Reporting - Various Formats

Step by step Guided User Interface

Data can be exported in different formats, such as tab limited ascii formats, binary, XML or NetCDF Format. The user can adjust the file content to his/her requirements: separate data according to parameters or save only a part of the measurement. Reports can be automatically generated in any format supported by Windows. The content and lay out of the format can be adapted to specific requirements, such as the CTIA certification reports.

83


A Multi-profile User Interface SAM offers different measurement configurations, depending on the user's level of expertise. Users with limited experience are guided through the different measurement steps, whereas more experienced users can access a full range of parameters.

Hardware configuration • Radio communication tester: Base station simulator

with measurement capabilities. It is the signal generator and measurement receiver. • Amplification unit: Includes uplink/downlink switch for

the SG or StarLab systems. • Link antenna: A low reflectivity antenna mounted inside

the positioning mast, close to the turntable.  It rotates with the DUT, maintaining a constant link, which reduces the risk of dropped calls during testing. • Active switching unit (optional): Allows automatic

switching between different test equipment. • I/O switch port (optional): Used specifically with

the MT8860C Anritsu WLAN test to separate the Radio Frequency IN/OUT port of the tester into 2 different paths: one for Transmitting (Tx) and one for Receiving (Rx).

Direct far-field measurement of electrically large antennas

SOLUTION FOR • Antenna measurement • Radome measurement • RCS measurement

A Compact Range makes direct far-field measurement of electrically large antennas in a shielded anechoic chamber. It uses a large parabolic reflector to project a small radiating source (feed) into the far field. Multiple-feed systems may be used to improve the far-field characteristics. The system also allows system level testing of the complete device architecture.

INSTRUMENTATION ROOM

A Compact Range operates like a regular far-field range, however it allows electrically large antennas to be measured at a significantly shorter distance. Its lowest operational frequency is determined by the size of the reflector, the edge treatment and the absorbers. The two edge treatments available are serrated edge for general purpose applications, and rolled edge to achieve higher accuracy for special applications (e.g. extremely accurate low sidelobe measurements). Shielding is optional. The performance of a Compact Range improves over frequency up to a level determined by the manufacturing accuracy of the compact range reflector. Considering the small sizes of high frequency antennas, the upper frequency can be well above 100 GHz. The performance of the Compact Range improves in relation to the increase in frequencies to be measured yet is limited to the level determined by the manufacturing accuracy of the reflector.

102

CHAMBER

The RF transmit/receive system is supported by a VNA. Depending on the size of the range, an amplifier may be required. Above certain frequencies, a remote mixing configuration is required to avoid high RF cable losses at higher frequencies. Dual polarized feeds and multiple channel DUTs can be handled by optional RF switches and the OFR 9800A high speed switch controller. The data acquisition workstation is equipped with either the 959 Spectrum or MiDAS software, depending on location. Both software packages are powerful data acquisition and analysis tools.

The engineer is mounting the arm for calibration

124

The probe array system calibration allows for both consistency in amplitude and in phase as well as the radio-electric axis alignment of each probe. The calibration procedure consists of the rotation of a reference antenna along a roll axis in front of each probe. This is performed with a dedicated calibration arm supporting the reference antenna and its motorized roll axis. Mounted on one of the linear axes of the scanner, the calibration arm moves linearly to position the reference antenna in front of each probe of the array.


I T-DualScan

DUT positioning system (optional) H

DUT positioning system with air cushion for easier movement.

Single-probe

The DUT positioner is composed of standard ORBIT/FR positioning equipment that can be adapted to the specific requirements of each customer. An innovative DUT positioner base allows for easy movement of the DUT positioning equipment, thanks to four air cushion pads. To move the DUT linearly, a simple air hose is connected to the four air pads' central manifold, and the system is slightly elevated on a thin air cushion (0.08 mm). The system has virtually no friction and can be moved simply by pushing it to its new position.

I Software

SatSIM Performance evaluation of antennas sited and operating in complex and electrically large environments is a difficult and complex measurement task.

SatSIM

SatSIM provides a user-friendly and economical way to accurately evaluate the behaviour of an antenna in its final operational environment. This is achieved by combining near-field measurement of the stand-alone antenna with the numerical modeling of its operational environment, based on a novel approach in ray tracing technique (Astigmatic Beam Tracer). The SatSIM software is an efficient extension to the fast measurement capabilities of the MVG spherical near-field measurement systems.

Measurement process Measurement of the stand-alone antenna

EM field computation

Astigmatic Beam-Tracing

Modelling of the environment

Input sources types: Measurements / Analytical / Equivalent Currents in single/multiple modes

Spherical near-field/far-field or planar near-field as output

The antenna source model can be obtained in real-time from measurements performed in the antenna test range. It offers a unique capability of assessing the performance of the antenna within its final operating environment as the stand-alone antenna is being measured.

Insight

Insight

In the antenna design or EMC testing process, the measured radiation pattern or shielding performance does not always correspond to what is expected. Identifying the source of the discrepancies can be a time-consuming process. Insight is the first software able to compute authentic electromagnetic current distributions and extreme near-field of the antenna under test from measured near- or far-field data. It allows quick and clear identification of the source of problems observed during measurement and provides in-depth understanding of antenna radiation characteristics. As a result, the antenna development cycle is reduced and time to market is shortened.

MV-Echo

MV-Echo

Spurious error signals from absorbers and other structures in the measurement set-up can significantly decrease the measurement accuracy in standard antenna measurement configurations. MV-Echo, the echo reduction toolbox, attenuates the effects of such undesired signals and significantly improves measurement accuracy. The algorithm of the module is based on the modal filtering of the fields in the Spherical Wave Harmonics domain. It is compatible with MVG software suites: SatEnv, MiDAS and 959 Spectrum. MV-Echo allows the users to: ➊  Filter out echoes in near-field (spherical, cylindrical and planar) and far-field measurement systems ➋ Optimize the AUT minimum sphere, thus the toolbox improves the filtering effectiveness ➌  Improve accuracy in the estimation of antenna performances: • 3D-Radiation Pattern • Directivity / Gain • Side Lobe Level (SLL) • Cross-Polar Discrimination (XPD) ➍ Apply to standard measurement set-up and AUT configurations in an easy post-processing step
