The PN9002 is a pulse-to-pulse radar stability test system. The PN9002 system enables measurements of amplitude and phase stability of radar pulses with a dynamic range. It integrates hardware and software to test a two-ports module for amplitude and phase stability. The PN9002 acts as a "micro-radar" providing pulsed signals to the unit under test and analyzing the received pulses. The system covers 400 MHz to 18 GHz in a scaleable configuration. The dynamic range reaches – 79 dBc in stability integration over the bandwidth of the equivalent receiver.
