    In the early 1980s, Hewlett-Packard introduced a new product that redefined the measurement of very short time intervals. The 5370 time interval counter has a resolution of 20 picoseconds (or 20 trillionths of a second).

    Although the 5370B is optimized for time interval measurements, it also has the ability to directly measure the frequency of a signal with a resolution of 12 digits at the maximum standard "gate time" of one second. For various reasons, the frequency counter performance isn't as good as the time interval measurement.

    ================================
    The 5370B precision time-interval universal counter offers unsurpassed single-shot resolution and a microprocessor-based design for versatile measurement and complete statistical characterization capabilities. The exceptional single shot resolution is achieved by a unique phase-lockable-phase-startable oscillator, used with a digital vernier interpolation scheme that eliminates the count quantization error present in most time-interval counters. Statistical functions include mean, maximum, minimum, and standard deviation within the selected sample size.

    The 5370B allows both positive and negative time interval measurements that are useful for differential phase measurement. Other features include automatic calibration of systematic errors and easy display of triggers. Performance, automation, and ease of use make the 5370B the premier time interval measurement counter for applications in component testing, radar/laser ranging, nuclear systems, calibrations labs, computer peripherals testing, digital communications (jitter analysis), and IC tester verification.
