[:SOURce<hw>]:SWEep[:FREQuency]:RETRace
<State>
Activates that the signal changes to the start frequency 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
FREQ:MODE SWE
SWE:SHAP SAWT
SWE:RETR ON
activates retrace function, i.e. the frequency changes to the
value at start frequency while waiting for the next trigger event.
Manual operation:
See
"Retrace - RF Frequency Sweep"
[:SOURce<hw>]:SWEep[:FREQuency]:RUNNing?
Queries the current state of the frequency sweep mode.
Return values:
<State>
0 | 1 | OFF | ON
Example:
SWE:RUNN?
Response
"1"
: signal generation in level sweep active.
Usage:
Query only
[:SOURce<hw>]:SWEep[:FREQuency]:SHAPe
<Shape>
Sets the cycle mode for a sweep sequence (shape).
Parameters:
<Shape>
SAWTooth | TRIangle
SAWTooth
One sweep runs from start to stop frequency. Each subsequent
sweep starts at the start frequency, i.e. the shape of the sweep
sequence resembles a sawtooth.
TRIangle
One sweep runs from start to stop frequency and back, i.e. the
shape of the sweep resembles a triangle. Each subsequent
sweep starts at the start frequency.
*RST:
SAWTooth
Example:
SOUR:SWE:SHAP TRI
selects the sweep cycle with alternating ascending and
descending sweep directions.
