Activating the frequency converter mode
To activate the converter mode for a setup without external generator, establish a
USB connection between converter and VNA. Wait for the dialog box to appear
and confirm the prompt "Configure Two-Port Measurement Setup…?". The VNA
then readd the characteristic data of the R&S
ZCxxx via USB and automatically
enter the appropriate converter mode.
Analyzer settings with active frequency converter
In frequency converter mode, the frequency and level settings of the net-
work analyzer are automatically set to be compatible with the selected fre-
quency converters. If the VNA allows for low phase noise mode, it is activa-
ted. Automatic Level Control (ALC) is disabled. Frequency and source
power levels of all ports are displayed in the port configuration dialog
("Channel > Mode > Port Config").
If a USB connection between VNA and converter is not possible, but has been
established previously, the characteristic data of the frequency converter are
already available at the VNA. In this case, open the "System Configuration" dialog
("System > System Config") and activate the "Frequency Converter" tab. Select
the adequate converter model in the "Type" combobox, select the LO sources in
"Use of External Sources", check the port assignment table and press "Apply" to
activate the setting.
