Agilent / HP / Keysight 5372A

This modulation domain analyzer, a superset of the 5371A, captures frequency, phase, or time intervals at extremely high speeds.

This can make up to 13.3 million measurements per second for signals with a frequency range of up to 500MHz.

An optional channel expands the range to 2GHz.

This combines a choice of over 60 arming and triggering configurations with built-in analysis functions including math, statistics, and limit testing.

Unique to this unit (compared with the 5371A) is deeper memory, hardware histograms, and FFT capabilities for high performance and more sophisticated jitter spectrum analysis and phase noise studies.

It 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.
