Validate mmWave Protocol Conformance and MIMO Performance

The Keysight multi-probe anechoic chamber (MPAC) family delivers a comprehensive solution for mmWave over-the-air (OTA) testing, enabling accurate validation of protocol conformance and MIMO performance. These systems support direct far-field measurements, multi-angle and multi-beam analysis, and full spherical coverage, ensuring realistic and repeatable test conditions. Optimized for 5G NR FR2, beamforming, and radio resource management (RRM) validation, MPAC systems also support sub-6 GHz signaling, providing flexibility across a wide range of test scenarios. The chambers feature advanced multi-probe configurations, integrated positioning and alignment tools, low path loss, and a modular architecture that enables easy setup, scalability, and future expansion. MPAC configurations can be tailored to your specific needs—from compact setups for protocol verification to fully equipped systems for comprehensive 3D MIMO performance evaluation of the device under test (DUT).

Highlights

Keysight’s F9642A 2D Multi-Probe Anechoic Chamber (MPAC) Pro is a shielded anechoic chamber for protocol and functional testing of FR2 frequencies with direct far-field capability and FR1 4X4 MIMO throughput capability supporting extreme temperature control and thermal imaging.

  • The chamber includes connections for up to six FR2 RF heads connected to a range of up to three feed antenna locations, arranged in an arc to simulate variable angles of arrivals or multiple beams. The FR2 antennas are located within the angle of +/-15° from the positioner rotation center, creating the angle of 30° for a range length of 106 cm.
  • There are four dual-polarized FR1 antennas located in each corner of the roof with room for polarization rotation to provide maximal signal de-correlation.
  • Thermal camera is also located on the roof to give unobstructed view to Device-Under-Test (DUT).
  • The DUT is placed in a software-controlled positioner, capable of providing full spherical coverage.
