R&S HM8021-4

This microprocessor based instrument has built-in self test as well as two high sensitivity inputs, with an extended frequency range to 1.6GHz for one of them. The reciprocal frequency measurement technique provides high resolution of low frequency signals with 7 significant digits for a 1s measurement duration. The HM8021-3 is equipped with an extremely stable temperature compensated crystal oscillator (TCXO) with a stability of 0.5 ppm over the entire operating temperature range. Readings of frequency, period, time interval and totalized count, up to 99,999,999, combined with the Display Hold function and a full range offset makes this instrument ideally suited for a broad range of applications. Mfg. part no. HM8021 is a universal counter module part of a moduar system used with mfg. part no. HM-8001 version 2 mainframe.
