SATIMO has developed a range of antenna measurement systems changing the approach to antenna measurements. Its patented multi-probe technology offers new perspectives that combine the advantages of fast measurements with geometries allowing minimal mechanical movements.

The speed factor enables more frequent testing of devices under development, thus allowing more interactions between simulation and prototyping. Indeed, the quasi-real time visualization of the radiation pattern of the antenna under test enables engineers to immediately adapt accordingly the prototype design. The integration of continuous measurements into the antenna design process improves the overall effi ciency of the development work. High quality products and adaptive measurement systems will be the future of the antenna industry. All measurement systems have been developed by SATIMO based on its two main product lines, StarLab and SG systems. These systems are aimed at optimi-zing the design, validation, certifi cation and produc-tion stages of all types of antennas. Our systems are able to characterize the performances of:

• Stand alone antennas (antenna measurements).• Antenna mounted on structure i.e. automotive/

aerospace and defense (antenna performance within a complex structure).

• Antennas integrated in mobile telecommunication devices (Over the Air measurements).

Electronically scanned probe array:

high speed combined with accuracy

The electronic scanning of probe arrays and the geometries used in SATIMO equipments are major improvements in the fi eld of antenna measurements.

1/ High measurement speed

The array of probes is electronically scanned, which means that a full cut can be measured and visualized in real time. Full 3D measurements are performed in a few minutes.

2/ Limited mechanical movements

SATIMO systems use geometries that minimize the number of necessary mechanical movements. In most classical spherical single-probe measurement systems, the DUT is rotated in azimuth from 0 to 360° and elevation from 0 to 180° in front of a single probe to determine the fi eld on a sphere surrounding the device. SATIMO spherical multi-probe systems limit mecha-nical movements to the 180° rotation of the DUT.

Minimizing mechanical movements enables:

• Improved accuracy of the measurement: movements are a source of disturbance.

• Increased repeatability of the measurement: increa-sed repeatability reduces the risk of error.

• Extended lifetime of the system: repeated move-ments may affect the reliability of mechanical parts.

Select the geometry to best suit

your application

For each kind of antenna and application there is a corresponding best test geometry. In addition, SATIMO proposes movable in-situ advanced measurement solutions.

1/ Geometries

An array of probes can be integrated in different systems’ architecture in order to best fi t a specifi c need:

• Spherical geometry: can be used to test any kind of antenna and is necessary to test wide-beam and omni-directional antennas: i.e. wireless devices testing, OTA systems...

• Cylindrical geometry: for semi-directive antennas i.e. BTS antennas.

• Planar geometry: for highly directive antennas: i.e. phased arrays, satellite communication antennas....

2/ Movable/Advanced Systems

Nowadays, demand for testing antennas integrated in complex structures is increasing; structures that might be diffi cult to bring into anechoic chambers or that might have antennas in positions that are diffi cult to reach. SATIMO designs and manufactures measure-ment systems that can be moved to the devices under test (indoors and outdoors); systems which also use smart, mechanical movement to bring the probe array to the antenna. Some examples can be found in the automotive and aerospace sections of this catalogue.

a large number of applications

SATIMO systems are open to the evolution of your measurement needs.

1/ Wide frequency band

3 families of probes combined with several sizes of supporting structures are available for measurements covering the 70 MHz to 18 GHz frequency range.Probes to reach 40 GHz are under development. Meanwhile 40 GHz systems can be delivered using a combination of single probe and SATIMO’s multi-probe technique.

2/ Amplitude and Phase measurements

SATIMO equipments are able to measure the phase and amplitude of the radiation pattern. This is particu-larly important for advanced post-processing:

• Calculate near and far fi eld measurement data.• Calculate back propagation/holography.• Use modal fi ltering to eliminate unwanted effects.• Standard antenna post-processing (directivity, effi ciency, 3D beamwidth...).

3/ OTA performance testing

SATIMO systems are particularly suited to perform Over The Air (OTA) Testing. The multi-probe approach drastically reduces the TRP (Total Radiated Power) measurement time, while the TIS (Total Isotropic Sensitivity) benefi ts from the latest processing improvements. Please see the Over The Air Testing section, page 39 for more information.

4/ Wearable antennas measurements

Using probe arrays allows interaction assessment between antennas and their environement. Hen-ce, with SATIMO measurement systems, wearable antennas can be measured while actually being worn. Those measurements complete simulation and phantom usage, and bring one step further the knowledge of the performances of those antennas in the fi eld.

StarLab: a compact movable solution

when space and budget are at stake

StarLab is the ultimate tool for antenna pattern measurements in laboratories and production environment, where space is limited, cost is critical and the fl exibility of a movable system is required.

StarLab

StarLab is mounted on wheels and can go through a standard double door. If needed, one of the two cylinders of absorbers can be removed, allowing it to pass through a standard single door.

StarLab uses a Switching Unit to switch between passive and active measurements RF instrumenta-tion. For passive measurements, a Vector Network Analyzer is used as the RF source/receiver for an-tenna measurements. The Control Unit drives the two positioning motors and the electronic scanning of the

probe array. For active measurements the test is per-fomed through a Multi Protocol Radio Communication Tester. Amplifi cation Units are added on both TX and RX chains. For Wi-Fi and other protocols that use de-dicated Radio Communication Testers the Switching Unit has dedicated ports.

Oversampling capabilityA combination of automated mechanical and electro-nically scanned probe array is available to provide un-limited scan resolution in both elevation and azimuth.

The spacing between two probes is 22.5°. This spa-cing is suitable for small antenna testing. For larger an-tennas, the position of the probe array can be mecha-nically offset. This “fi lls in the gaps” between the probes and provides the possibility of unlimited sampling.

2/ OTA performance testing with StarLab

StarLab can perform both TRP and TIS measure-ments. For TIS measurements, or where external in-terference is a problem, a shielded chamber is neces-sary. A small shielded chamber for StarLab is available. The chamber is lined with pyramid absorbers on the two walls facing the openings of the StarLab anechoic cylinders.

3/ Linear scanner option (BTS antenna mesurement)

By adding a linear scanner, StarLab is converted from a spherical to a cylindrical near fi eld measurement system, which is particularly suitable to BTS antenna measurements. In addition to the standard features, this confi guration allows the measurements of the beam tilt. StarLab BTS can measure sidelobes up to typically 70° from boresight.

The most accurate solution to test antennas and wireless devices

SG 64 has been developed to measure stand alone antennas or antennas integrated in subsystem (see specifi cation table on the following page). It is also ideal for CTIA certifi able measurement facilities.

SG system can switch between the Probe Array Controler (PAC) for passive measurements and the Radio Communication Tester for active measure-ments. For passive measurements it uses Analog RF Signal Generators for emitting from the probe array to the Antenna Under Test or from the Antenna Under Test to the probe array. The PAC is also a RF receiver for antenna measurements. The PAC controls as well

the electronic scanning of the probe array. The Am-plifi cation Unit has RF amplifi ers for both RX and TX channels. For active measurements, the test is perfor-med thanks to a Multi-protocol Radio Communication Tester. It is used to communicate with the DUT and to measure the Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS).

SG system: oversampling functionSG LF version with two kinds of probes

Oversampling capabilityA combination of automated mechanical and electronically scanned probe array is available to provide un-limi-ted scan resolution in both elevation and azimuth.

The spacing between two probes is 5.29º. This spacing is suitable for small antenna testing. For larger antennas, an additional mechanical rotation is combined to the probe array. In this case, the positioning mast rotates with ±2.6° in elevation, in order to adjust the position of the DUT on offset locations. This “fi lls in the gaps” and provides the possibility of unlimited sampling.

Its compact dimensions make it perfect for offi ce buildings and labs

where ceiling height is limited

SG 32 is a downscale version of the SG 64 with 31 probes (+ 1 reference channel).

SG system can switch between the Probe Array Controler (PAC) for passive measurements and the Radio Communication Tester for active measure-ments. For passive measurements it uses Analog RF Signal Generators for emitting from the probe array to the Antenna Under Test or from the Antenna Under Test to the probe array. The PAC is also a RF receiver for antenna measurements. The PAC controls as well

the electronic scanning of the probe array. The Am-plifi cation Unit has RF amplifi ers for both RX and TX channels. For active measurements, the test is perfor-med thanks to a Multi-protocol Radio Communication Tester. It is used to communicate with the DUT and to measure the Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS).

The ideal solution for the performance testing of wireless devices

It is compliant to the CTIA OTA performance measurement specifi cations. SG24 was originally designed for active testing only. It is now also available for passive antenna measurements.

SG 24 uses a switching Unit to commute between pas-sive and active measurements RF instrumentation. For passive measurements it uses a Vector Network Ana-lyzer as the RF source/receiver for antenna measure-ments. The control Unit also drives the two positioning motors and the electronic scanning of the probe array.

For active measurements the test is perfomed through a Multi Protocol Radio Communication Tester. Amplifi -cation Units are added on both TX and RX chains. For Wi-Fi and other protocols that use dedicated Radio Communication Testers the Switching Unit has dedi-cated ports.

Add-on OTA performance testing SW

and HW modules for both StarLab

and SG measurement systems

SATIMO systems are particularly suited to testing wireless devices in active mode. It is our companystrategy to follow the evolution of the different tele-communication protocols and to be present in the standardization committees to actively contribute to the test plan drafting.

SATIMO systems: by far the fastest in testing both TRP and TIS

1/ Total Radiated Power (TRP)

TRP is the total RF channel power radiated by a wire-less terminal. It is calculated by integrating the measu-red Effective Isotropic Radiated Power (EIRP) data over the measurement sphere. The EIRP is measured at a minimum every 15 degrees in both elevation and azimuth. This accounts for a total of 1656 measure-ment points (23 elevations × 12 azimuths × 2 polari-zations × 3 frequencies), with a typical measurement time of about 3 minutes (depending on the protocol and equipment).

2/ Total Isotropic Sensitivity (TIS)

TIS is a fi gure 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 at a minimum every 30 degrees in both elevation and azimuth. This accounts for a total of 396 measure-ment points (11 elevations × 6 azimuths × 2 polari-zations × 3 frequencies), with a typical measurement time of about 90 minutes (depending on the protocol and equipment).

The EIS is found with a search algorithm that fi nds the mini-mum power level radiated onto the DUT for which the bit error rate is lower than a specifi ed limit.

Shorten Measurement Time

SATIMO offers several methods to reduce the TIS measurement time. One of them, the TIS based on Rx level, uses the DUT receiver as power meter with certain communication protocols (like GSM and WCD-MA). From each measurement point on the measure-ment sphere, a constant power is radiated towards the DUT. The DUT receiver then reports back its re-ceived power level and the complete spherical set of power level data can be referenced to a single-point EIS measurement to determine the TIS.

3/ Software

SAM2 is the software interface for automated OTA performance testing with StarLab and SG measu-rement systems. It enables measurements of both radiated power and sensitivity, supporting most of the common wireless communications protocols:GSM, GPRS, EDGE, CDMA2000, CDMA 1xEVDO, CDMA 1xRTT, WCDMA, HSDPA, Wi-Fi 802.11 a/b/g, BLUETOOTH 802.15.1.2, PHS, TD-SCDMA, HSPA, WiMAX, GPS, DVB-H (Contact us for an updated list).

CTIA reporting supported

Data can be exported in different formats, such as tab limited ascii formats, binary, XML or NetCDF For-mat. The user can adjust the fi les content to his/her requirements: separate data according to parameters or store only a part of the measurement.Reports can be automatically generated in any formatsupported by Windows. The content and lay out of the format can be adapted to specifi c requirements, such as CTIA certifi cation reports.

A Multi-profi le User Interface

SAM2 offers different measurement confi gurations, depending on the level of expertise of the user. Users with limited experience are guided through the dif-ferent measurement steps, whereas experimented users can access a full range of parameters.

4/ Hardware confi guration

• Radio Communication Tester: A Radio Com-munication Tester is a base station simulator with measurement capabilities. It is the signal generator and measurement receiver.

• Uplink/Downlink Switch is included in the Amplifi -cation Unit of the SG or StarLab.

• Link antenna: is a low refl ectivity antenna moun-ted inside the positioning mast, close to the turnta-ble. It rotates with the DUT, maintaining a constant link, which reduces the risk for dropped calls during testing.

• Active Switching Unit (optional): allows to switch automatically between different test equipments.

• Wideband Dynamic Range Adapter (optional): It is a step attenuator allowing SAM2 to automatically adjust the output range of the Radio Communica-tion Tester.

SG 4000M: for in-situ measurements

These systems are movable and aim at reaching an antenna that cannot easily be placed on a positioner: antennas on board of large or complex structure.

They can either measure the whole structure or if it is too large (i.e. an aircraft) the antenna with a por-tion of structure around it (quasi local near fi eld ap-proach). The rest of the structure is taken into account through post processing software simulation (SatSim).

Satimo has developed a product line, the SG 4200M, in this family range for in-situ Radar testing purposes.

About SATIMO

SATIMO specializes in the design and manufacturing of antenna measurement systems. The company has mo-ved antenna measurement techniques forward with a unique, innovative multi-probe technology. The technology is based on the use of arrays of probes that are electronically scanned to measure electromagnetic fi elds. This technology has brought two major changes in the fi eld of antenna measurement: the speed (a single electronic scan allows the visualization of the fi elds in 1D or 2D almost instantaneously) and the fl exibility (the array can be integrated in any kind of geometry for both indoor and outdoor measurements). SATIMO is part of Microwave Vision SA, which includes ORBIT/FR and AEMI, and offers full turnkey systems to measure a stand alone antenna or antennas integrated into complex structures.
