Remote command:
[:SOURce]:LFOutput<ch>:INTernal:VOLTage on page 466
DC-Offset
Adds a DC offset to the LF output signal.
Remote command:
[:SOURce]:LFOutput:OFFSet on page 466
Source Impedance
Selects the output impedance of the LF generator.
"50 Ω"
Selects an output impedance of 50 Ω.
"600 Ω"
Selects an output impedance of 600 Ω.
Remote command:
[:SOURce]:LFOutput:SIMPedance on page 467
Load Impedance
Sets the specification of the load impedance interconnected to the LF generator output.
This parameter is available in case of activated R&S SMB100A or R&S SML0x emula-
tions only, see "Remote Access Settings" > "Instrument Emulations" > "Language"
on page 293.
These signal generators come with an LF generator source impedance of 10 Ohm
which is not available with the R&S SMB100B.
The set LF generator load impedance enables the R&S SMB100B to emulate the
10 Ohm LF generator source impedance of these generators by a corresponding
increase of the open circuit LF generator output voltage.
The load impedance setting is not affected by an instrument preset ([Preset] key or
*RST), restart or the "Save/Recall" function. It is reset to the default value of 1 MOhm
by a factory preset only.

Noise Level
Access:
●
Select "Modulation" > "Output > Noise Level".
Noise Density ← Noise Level
Indicates the level of the noise signal for a bandwidth of 1 Hz (relative).
