53210A Measurements

Keysight 53210A User’s Guide

Frequency Ratio Measurements

A frequency ratio measurement is the measurement of two signals in which one

signal generally serves as a reference (

Figure 3-2

). The signals can be different

wave shapes and applied to any 2-channel combination on the counter.

Figure 3-2

Ratio of Two Input Signal Measurements.

The commands used to make frequency ratio measurements are:

numerator channel

denominator channel
