3.5 Connecting the Frequency Converters
Each frequency converter must be connected to the analyzer, the power supply and
the DUT. Please refer to the following sections for details.

3.6 Power and Frequency Settings
While the frequency converter mode is active, the "Channel > Stimulus" settings of the
network analyzer control the frequency and power range of the converters. In addition
the "Channel > Mode > Port Configuration" dialog shows an additional row for each
converter. The "Power" and "Frequency" settings in the "Source" section of the dialog
serve different purposes:
●
The "Power" setting defines the output power for each converter. A source power
calibration of the converter port ensures that the analyzer will generate the
selected source power; see
●
The source frequency at the converter ports is essentially determined by the port
frequency of the analyzer. The converter frequency settings in the "Port Configura-
tion" dialog define the frequency axes for the source power calibrations, however,
they do not actually affect the converter output frequencies. For best accuracy,
ensure that the correct converter frequencies are set, especially if the test setup
contains additional frequency-converting components.
