R&S SMB Command Description
1407.0806.32 6.47 E-2
[SOURce:]LFOutput:SWEep[:FREQuency]:SOURce LF1 | LF2
The command selects the source for the LFsweep.
Example:
SWE:LFS LF2
'selects LF generator 2 as the LF frequency sweep source
*RST value Resolution Options SCPI
LF1 - Device-specific
[SOURce:]LFOutput:SWEep[:FREQuency]:SPACing LINear | LOGarithmic
The command selects linear or logarithmic sweep spacing.
Example:
LFO:SWE:SPAC LIN
'selects linear sweep spacing.
*RST value Resolution Options SCPI
LINear - - Device-specific
[SOURce:]LFOutput:SWEep[:FREQuency]:STEP[:LINear] 0 ... (STOP - STARt)
The command sets the step width for the linear sweep.
This command is linked to the command :LFOutput:SWEep[:FREQuency]:POINts as follows:
The following applies for STARt < STOP: POINts = (((STOP-STARt) / STEP:LIN) + 1
If STEP:LIN changes, the value of POINTs is adjusted. The STARt and STOP value is retained.
Example:
LFO:FREQ:STAR
'sets the start frequency to 2 kHz.
LFO:FREQ:STOP
'sets the stop frequency to 20 kHz.
LFO:SWE:SPAC LIN
'sets linear sweep spacing.
LFO:SWE:STEP 2 kHz
'sets the sweep step width to 2 kHz. The number of sweep steps for linear
sweep spacing (POINts) is automatically set to 11.
*RST value Resolution Options Correlation SCPI
1kHz 0.1 Hz -
The value of :LFO:SWE:POIN is
adjusted automatically.
