Measurement of Mixers

The frequency-offset function allows you to measure frequency-translating devices such as
mixers.

1. Setting Frequency-Offset

The frequency-offset function allows you to implement the measurements in which
frequencies are different for each port, such as in mixer measurement. The frequency set
for each port can be applied to the port even if it is for stimulus or receiver.
NOTE You can set the frequency-offset for each channel independently.
