Define Mixer Meas...
Opens a configuration dialog for the mixer input signals.
In the upper part the Define Mixer Measurement dialog shows a diagram with the RF and LO signals,
the mixing product (IF), and the current frequency and power ranges for all signals. Below the dialog
provides the following control elements:
•
The port selection list contains all analyzer ports or external generators which can provide the
local oscillator (LO) signal. Ports no. 1 and 2 are always used for the RF signal and the
measured IF signal (mixing product), so they are not included in the list. Generators must be
configured explicitly in the
System Configuration – External Generators dialog before they
appear in the list. None means that the input signal at LO (if available) is not controlled by the
analyzer.
•
Config Ext. Generators... opens the System Configuration – External Generators dialog for
adding and configuring external generators.
•
Set Power... opens a dialog to control the power of the RF and the LO signals.
•
Set Frequencies... opens a dialog to control the frequency of the RF and the LO signal and the
analyzer (IF signal) frequency.

Mixer Signal Diagrams...
The mixer signal diagrams show the parameters of the mixer input signals (RF, LO) and of the mixing
product (IF signal, output). The diagrams appear in the Mixer Measurement, Set Power, and Set
Frequencies dialogs.
