System overview Data Acquisition & Processing PC Primary Synthesizer Mixer Unit Auxiliary Synthesizer Radio Communication Tester Active Switching Unit Amplification Unit Motion Controller SG 64 can switch between N-PAC for antenna measurements and the Radio Communication Tester for OTA measurements. For antenna measurements, it uses Analog RF Signal Generators to emit from the probe array to the Antenna Under Test or vice versa. The N-PAC is also a RF receiver for antenna measurements and it controls the electronic scanning of the probe array. For OTA measurements, the tests are performed...
