Parameters:
<Mode> CW | FIXed | SWEep
CW|FIXed
The instrument operates in fixed-frequency mode. CW and
FIXed are synonyms.
The output frequency is set with [:SOURce]:LFOutput<ch>:
FREQuency.
SWEep
The instrument operates in SWEep mode. The frequency is set
using the commands [:SOURce]:LFOutput:FREQuency:
STARt, [:SOURce]:LFOutput:FREQuency:STOP or [:
SOURce]:LFOutput:FREQuency:MANual.
*RST:
CW
Example:
LFO:FREQ:MODE SWE
sets the SWEep mode. The settings under
SOURce:LFOutput:FREQuency:STARt; STOP; MANual
become effective.
Manual operation: See "State - LF Sweep" on page 190
[:SOURce]:LFOutput:FREQuency:STARt <Start>
This command sets the start frequency for the LF Sweep mode.
Parameters:
<Start> float
Range: 0.1 Hz to 1 MHz
Increment: 0.1 Hz
*RST: 1 kHz
Example:
RST*
activates all presettings.
LFO:SWE:MODE AUTO
sets the AUTO sweep mode, i.e. each trigger triggers a complete
sweep.
TRIG0:SOUR SING
sets the SINGle trigger mode, i.e. the sweep is triggered by the
command :LFOutput:SWEep:EXECute or *TRG.
LFO:FREQ:STAR 100 kHz
sets the start frequency for the LF sweep to 100 kHz.
LFO:FREQ:STOP 200 kHz
sets the stop frequency of the LF sweep to 200 kHz.
LFO:FREQ:MODE SWE
sets the LF sweep mode.
LFO:SWE:EXEC
a one-off LF sweep from 100 kHz to 200 kHz is performed. The
linear step width is 1 kHz with a dwell time of 15 ms (preset values).
