The HP/Agilent 5371A is a high-performance frequency and time interval analyzer engineered for precision measurement of frequency, time interval, phase, and pulse characteristics. Built on continuous measurement time sampling architecture, the instrument eliminates dead time between measurements and delivers over 10 million measurements per second with zero latency—enabling rapid data acquisition for telecommunications, metrology, and research applications.
