Example:
TRIG0:SWE:SOUR SING
LFO:SWE:MODE SWE
LFO:SWE:SHAP SAWT
LFO:SWE:RETR ON
activates retrace function, that menas the frequency changes to
the value at start frequency while waiting for the next trigger
event.
Manual operation: See " Retrace - LF Frequency Sweep " on page 185
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:RUNNing?
Queries the current status of the LF frequency sweep mode.
Return values:
<State> 0 | 1 | OFF | ON
Example:
LFO:SWE:RUNN?
Response "1": the frequency sweep is running.
Usage: Query only
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SHAPe <Shape>
Sets the cycle mode for a sweep sequence (shape).
Parameters:
<Shape> SAWTooth | TRIangle
SAWTooth
A sweep runs from the start to the stop frequency. A subsequent
sweep starts at the start frequency, that menas the shape of the
sweep sequence resembles a sawtooth.
TRIangle
A sweep runs from the start to the stop frequency and back,
thatnt menas the shape of the sweep resembles a triangle. A
subsequent sweep starts at the start frequency.
*RST: SAWTooth
Example:
SOUR:LFO:SWE:SHAP TRI
selects the sweep cycle with alternating ascending and
descending sweep directions.
Manual operation: See "Shape" on page 184
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SPACing <Spacing>
Selects the mode for the calculation of the frequency sweep intervals.The frequency
increases or decreases by this value at each step.
