Source State
Activates or deactivates control of an external generator.
Remote command:
SOURce<si>:EXTernal<gen>[:STATe]
Source Power
The output power of the external generator. The default output power is -20 dBm. The
range is specified in the data sheet.
Remote command:
SOURce<si>:EXTernal<gen>:POWer[:LEVel]
Source Offset
Constant level offset for the external generator. Values from -200 dB to +200 dB in 1
dB steps are allowed. The default setting is 0
dB. Offsets are indicated by the "LVL"
label in the channel bar (see also
"Displayed Information and Errors"
Using this offset, attenuators or amplifiers at the output connector of the external gen-
erator can be taken into account. This is useful, for example, for the displayed output
power values on screen or during data entry. Positive offsets apply to an amplifier,
while negative offsets apply to an attenuator after the external generator.
Remote command:
SOURce<si>:POWer[:LEVel][:IMMediate]:OFFSet
Source Frequency Coupling
Defines the frequency coupling mode between the R&S
FSMR3 and the generator.
For more information on coupling frequencies, see
"Auto"
Default setting: a series of frequencies is defined (one for each
sweep point), based on the current frequency at the RF input of the
R&S
"(Automatic) Source Frequency (Numerator/
on page 132). The RF frequency range covers
the currently defined span of the R&S
FSMR3 (unless limited by the
range of the signal generator).
"Manual"
The generator uses a single fixed frequency, defined by
which is displayed when you select "Manual" cou-
pling.
Remote command:
SOURce<si>:EXTernal<gen>:FREQuency:COUPling[:STATe]
