The Agilent 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.
