Using The Frequency And Phase Reference Softkeys - Keysight Technologies N5171B EXG User Manual

When using the signal generator as the input to a system, you can set the frequency multiplier so
that the signal generator displays the output of the system, as illustrated below using a doubler:
Signal Generator
Input = 2 GHz
When measuring mixers, the frequency multiplier and frequency offset are often used together. In
the upconverter example below, the multiplier is set to
-1 and the offset is set to 3 GHz so that the signal generator displays f
f = 2200 2400 MHz

Using the Frequency and Phase Reference Softkeys

The MXG/EXG can be set to have either a user-determined frequency or phase reference.
