IF Frequency
Defines the intermediate frequency at the related port. Defaults to the IF of the
selected Converter Type.
If you specify an IF below 28 MHz, then during spectrum measurements the firmware
automatically adjusts the IF to 31.25 MHz.
Remote command:
[SENSe:]CONVerter<Port>:IFRequency
IF Input
Selects the IF input connectors to be used.
"Dir. Access"
requires Chapter 4.7.26, "Direct generator/receiver access",
on page 277
"Rear IF"
requires Chapter 4.7.29, "Direct IF access", on page 278
Remote command:
[SENSe:]CONVerter<Port>:IFPort
Active
Activates/deactivates the converter configuration for the related port.
Remote command:
[SENSe:]CONVerter<Port>:STATe
Source
Displays the related source port on the VNA (read-only).
Remote command:
[SENSe:]CONVerter<Port>:RFPort?
Local
Defines the source for the LO In port of the converter.
In general, if two or more converters are used in a measurement, it is recommended to
distribute a single LO signal to all converters using a splitter. Select "Splitter 1" or
"Splitter 2" in this case and use the intended LO source as source of "Splitter <i>"
on page 830 instead.
"None"
No LO source assigned. Results in an invalid converter configuration
that cannot be activated.
"Port <i>"
Use a VNA port that is not used as converter port as the LO source.
"Gen <i>"
Use an external generator as LO source.
"Splitter <i>"
Distribute the LO source via a splitter. "Splitter 2" is only useful, if 2
independent 2-port converter measurements shall be performed.
"LO Out"
Use the optional LO Out at the rear panel as LO source.
If compatible with the overall converter setup, the source providing the LO IN signal to
a frequency converter is automatically configured as permanent (Source Gen).
