II. Improve the Accuracy of Frequency Measurement
This Section illustrates how to use the frequency counting function of the S5105D/E/F microwave analyzer
to improve the frequency measurement readout accuracy by taking a measurement of a 500MHz signal
as an example.
The operation steps for using the frequency counter function are as follows:
a) Connect the output of the signal generator to the spectrum input port of the microwave analyzer via a
cable, and connect the 10MHz reference signal output of the signal generator to the external
reference input of the microwave analyzer with a BNC cable as shown in Figure 5-14:

b) Set the output frequency of the signal generator to a point frequency of 500MHz and an output
power of -10dBm to turn on the RF output of the signal generator.
c) Reset the microwave analyzer:
