HP 5314A Universal Counter

The HP 5314A is desktop portable 7 digits 100 MHz / 100 nsec universal counter. The counter has seven functions performance, overflow indication and input signal conditioning.

The seven functions are: frequency measurement, single-shot period, period average, time interval, totalize, ratio, and self check. The input signal is AC coupled and fully conditioned as follow: slope selection, trigger level and attenuation.

The HP 5314A has been produced by Hewlett Packard with two options:
