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)

The 53230A Universal Frequency Counter/Timer offers continuous/gap-free measurements for basic modulation domain analysis and optional basic burst microwave measurement capabilities up to 15 GHz.

The Keysight 5372A modulation domain analyzer, a superset of the 5371A, captures frequency, phase, or time intervals at extremely high speeds. The 5372A can make up to 13.3 million measurements per second for signals with a frequency range of up to 500 MHz. An optional channel expands the range to 2 GHz. The 5372A combines a choice of over 60 arming and triggering configurations with built-in analysis functions including math, statistics, and limit testing.

Unique to the 5372A (compared with the 5371A) are deeper memory, hardware histograms, and FFT capabilities for high-performance and more sophisticated jitter spectrum analysis and phase noise studies. The 5372A lets you: analyze jitter effects, characterize the transient and steady state responses of a VCO, examine frequency or phase modulation, measure frequency stability, analyze computer peripherals, or measure fast hopping radio signals.
