HP / Agilent 5372A Frequency and Time Interval Analyzer

The HP/Agilent 5372A Frequency and Time Interval Analyzer delivers high-resolution characterization of timing signals across multiple domains. This instrument measures frequency to 500 MHz (Channels A and B) or 2 GHz (Channel C with Option 030), period, time interval, phase deviation, time deviation (jitter), pulse width, duty cycle, rise/fall time, and dual-channel totalization. Capable of acquiring up to 13.3 million measurements per second for signals up to 500 MHz, the 5372A combines fast measurement throughput with exceptional resolution—achieving 150 ps rms on time interval and 2 ps LSD on averaged frequency measurements.
