​​ETS-Lindgren’s EMQuest EMQ-100 Antenna Measurement Software offers a wide range of fully parameterized test methods for measuring basic antenna performance metrics, as well as testing both radiated and conducted performance of various wireless devices. Whether you’re designing antennas for stand-alone applications, or testing an embedded antenna system and radio module against any of the industry standard Over-the-Air (OTA) radiated performance test requirements, EMQuest EMQ-100 provides the flexibility to meet your testing needs.

Key Product Information

​​OTA Evaluation

Using appropriate wireless communication testers and power measurement devices from the list of optional test equipment drivers, OTA performance can be evaluated for a broad range of wireless technologies, including:



  • LTE

  • CDMA, 1xEV-DO

  • TDMA


  • AMPS

  • Wi-Fi

  • WiMAX

  • Bluetooth

TRP/TIS Testing

For Total Radiated Power (TRP) Testing, the device is configured to transmit full power while the effective isotropic radiated power (EIRP) is measured at each point on the surface of a sphere around the device, generating a radiated power pattern.

The suite of tests includes spherical pattern measurements for determining transmit and receive total power metrics, including:

  • TRP


For total Isotropic/Radiated Sensitivity (TIS/TRS) Testing, the digital error rate is evaluated as a function of downlink signal level at each point around the device to determine effective isotropic sensitivity (EIS) and produce a sensitivity pattern.
The resulting EIRP/EIS patterns are then integrated to determine TRP/TIS as well as partial surface metrics such as:


  • Upper/Lower Hemisphere Partial Power/Sensitivity

  • and More!

A number of optimizations and industry firsts are provided to accelerate testing, including theta-dependent phi optimization, where the angular resolution is reduced near the “poles” of the pattern to reduce the required test time and maintain a more even surface resolution, and received signal strength (RSS) based sensitivity measurements that use RSSI reports from the mobile device to capture receive pattern information and greatly improve TIS test times. When used in conjunction with appropriate test systems, special test modes including high speed triggered acquisition and spiral data acquisition allow for extremely fast compliant and pre-compliant testing of TRP and transmit antenna patterns. Specialized tests for measuring intermediate channel sensitivity, interference, or degradation are included to determine the potential self-interference on all wireless channels where total surface testing would be impractical and time consuming. In addition, wireless desensitization testing is provided to evaluate the impact of one interfering embedded radio on the performance of another. Using appropriate optional test equipment, this test meets the requirements of the CTIA/Wi-Fi Alliance Converged Devices Test Plan.​​
