This analyzer is capable of many different measurements: single shot, precision VCO characterization (settling time, over-shoot, and post-tuning drift); jitter analysis (time deviation and FFT displays; optional jitter spectrum analysis software and FastPort interface); phase-locked loop studies; frequency stability measurements. Characterizing frequency modulation and drift measure signals ranging from 125 milli-Hz to 500 Mhz (up to 2 GHz with channel C)
