Aeroflex PN9500 18.00GHz Spectrum Analyzer

The Aeroflex PN9500 is an 18 GHz spectrum analyzer built on a modular architecture for RF and microwave signal analysis. It delivers phase noise measurement, jitter analysis, and real-time spectrum monitoring in a single instrument. The modular design supports frequency coverage from 2 MHz to 140 GHz with appropriate module configuration, while the core unit covers DC to 18 GHz for wideband monitoring.

Beyond spectrum analysis, the PN9500 integrates a frequency counter, digital oscilloscope, and power meter.
