The Keysight F9650A is a Compact Antenna Test Range (CATR) chamber engineered for over-the-air (OTA) characterization of wireless devices and antenna systems at millimeter-wave frequencies. It delivers a controlled anechoic environment with a rolled-edge parabolic reflector and dual-polarized feed horn assembly, enabling accurate RF performance measurements across 5G NR design verification, RF conformance, radio resource management (RRM), angle of arrival (AoA), RF demodulation, and carrier acceptance testing in compliance with 3GPP standards and certification bodies including GCF, PTCRB, and CTIA.
