First, the HP-5390A frequency stability analyzer HP-5390A using beat method and dual-frequency method, automatic measurement of signal frequency and time domain stability, fast and accurate. Is a typical example of computers going deep into frequency measurement. The main components of the HP-5390A frequency stability analyzer are: 1. Countdown Calculator HP-5390A This counter is one of the key components of the system by measuring the time-to-frequency and time resolution of 2ns. Mainly used to measure the frequency of various signals. 2. Mixing / Placement Unit HP-10830A is used to beat the signal under test and the reference signal, and meanwhile, the filtering and amplification functions so that the leading edge of the beat signal is smaller than
