Reference Frequency
Sets the frequency of the reference signal between R&S
SMW and frontend.
The R&S
SMW provides reference frequencies of 10
MHz, 640
MHz and 1
GHz.
"1GHz"
Requires R&S
SMW-B10xx/B20xx, i.e. a four-digit frequency option.
Remote command:
[:SOURce<hw>]:EFRontend:FREQuency:REFerence
[:SOURce<hw>]:EFRontend:FREQuency:REFerence:LIST?
Connection Mode
Sets the mode of the SSL control connection between R&S
SMW and external fron-
tend.
There is one communication channel to control the external frontend meaning that one
instrument controls the external frontend exclusively.
Once the external frontend is locked, the R&S
SMW firmware reads out external fron-
tend characteristics such as intermediate frequency (IF) and frequency bands.
