The current state of the RF output (activated and deactivated) is indicated in the main
panel with the different block color (blue or gray) and the status "On/Off".
Remote command:
:OUTPut[:STATe] on page 245
Mod State
Switches the I/Q modulation on and off.
Remote command:
[:SOURce]:IQ:STATe on page 270
PEP
Displays the Peak Envelope Power (PEP) of the RF signal of the selected instrument.
The value is calculated as follows:
"PEP" = Level + Crest Factor
Remote command:
[:SOURce]:POWer:PEP? on page 276
Level/Level Offset
Sets the RF level at the RF output connector of the selected instrument.
If you set a level offset, it will be indicated in the R&S SGMA-GUI main panel by a
change in the name of this parameter from "Level" to "Level Offset".
Note: The SCPI command [:SOURce]:POWer[:LEVel][:IMMediate][:
AMPLitude] sets the level of the "Level" display, that means the level containing off-
set while [:SOURce]:POWer:POWer sets the level at the RF output connector.
Remote command:
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPLitude] on page 275
[:SOURce]:POWer:POWer on page 274
Ref. Oscillator Source/Ext Ref On/Off
Determines whether the internal built-in oscillator (TXCO or OXCO) is used as a refer-
ence source or if an external reference is used. The internal reference oscillator OCXO
requires the additional option R&S SGS-B1.
To feed in an external instrument reference, use the input connector "REF/LO IN". To
output the reference frequency at the output "REF/LO OUT", select "SGMA-GUI >
Instrument Name > Ref. Oscillator > REF/LO Output > REF".
See also Chapter 11.4, "How to configure the reference oscillator source",
on page 165.
"Int"
The internal reference signal of 10 MHz is used.
"Ext"
An external reference signal is used. The frequency of the external
reference signal must be selected with the parameter "SGMA-GUI >
Instrument Name > Ref. Oscillator > Ex. Ref. Input Frequency".
