The diagram contains the mixer signal diagram and the following control elements:
•
The RF Power radio button groups specify how the power for each signal is defined. The roles
of the mixer input signals RF and LO are interchangeable: One signal is at the analyzer's
channel power
(Sweep or CW, the signal is swept if a power sweep is active; it is at fixed power
(CW) for the other sweep types), the other is at the Fixed power defined below.
•
The input fields in the Sweep/CW Power panel define the channel power and overwrite the
power settings in the Channel – Stimulus and Channel – Power Bandwidth Average menus.
The sweep range or CW power is assigned to the signal with Sweep/CW power definition.
•
Fixed Power defines the power to be assigned to the signal with Fixed power definition.

Set Frequencies
Controls the frequency of the RF and the LO signal and the analyzer (IF signal) frequency.
The diagram contains the mixer signal diagram and the following control elements:
•
The ... Frequency radio button groups specify how the frequency for each signal is defined. The
roles of the three signals RF, IF, LO are interchangeable: One signal is at the analyzer's
channel frequency
(Swept/CW, the signal is swept if a frequency sweep type is active; it is a
CW signal for the other sweep types), the second is at the Fixed frequency defined below, the
frequency of the third signal is calculated according to the selected Conversion formula.
•
The input fields in the Swept Frequency panel define the channel frequency and overwrite the
Channel – Stimulus settings. The sweep range or CW frequency is assigned to the signal with
Swept/CW frequency definition.
