The NXA-50 from Noise eXtended Technologies is a fully automated Phase Noise analyzer that operates from 5 MHz to 50 GHz. Its dual channel architecture allows the system to use a cross-correlation process to cancel its internal noise floor. This reliable combination enables absolute or residual phase noise measurements down to the thermal noise and offers a frequency offset from 0.01 Hz up to 40 MHz. A completely new user interface based on a large 14 inch touchscreen makes this analyzer easy to use. It is an ideal for Defense and Space applications where Radar signals going through AESA antenna T/R modules need to be tested for challenging noise floor and ultra low spurious detection.
