[:SOURce<hw>]:SWEep:POWer:RETRace <State>
Activates that the signal changes to the start level value while it is waiting for the next
trigger event.
You can enable this feature, when you are working with sawtooth shapes in sweep
mode "Single" or "External Single".
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
0
Example: TRIG0:SWE:SOUR SING
POW:MODE SWE
SWE:POW:SHAP SAWT
SWE:POW:RETR ON
activates retrace function, i.e. the level changes to the value at
start level while waiting for the next trigger event.
[:SOURce<hw>]:SWEep:POWer:RUNNing?
Queries the current state of the level sweep mode.
Return values:
<State> 0 | 1 | OFF | ON
Example: SWE:POW:RUNN?
Response
"1"
: signal generation in level sweep active.
Usage: Query only
[:SOURce<hw>]:SWEep:POWer:SHAPe <Shape>
Sets the cycle mode for a sweep sequence (shape).
Parameters:
<Shape> SAWTooth | TRIangle
SAWTooth
One sweep runs from the start level to the stop level. The subse-
quent sweep starts at the start level again, i.e. the shape of
sweep sequence resembles a sawtooth.
TRIangle
One sweep runs from start to stop level and back, i.e. the shape
of the sweep resembles a triangle.Each subsequent sweep
starts at the start level again.
*RST:
SAWTooth
Example: SOUR:SWE:POW:SHAP TRI
selects the sweep cycle with alternating ascending and
descending sweep directions.
