[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:MODE <Mode>
Sets the cycle mode of the LF sweep.
Parameters:
<Mode> AUTO | MANual | STEP
AUTO
Performs a complete sweep cycle from the start to the end value
when a trigger event occurs.
The dwell time determines the time period until the signal
switches to the next step.
MANual
Performs a single sweep step when a manual trigger event
occurs.
The trigger system is not active. To trigger each frequency step
of the sweep individually, use the command [:SOURce<hw>]:
LFOutput:FREQuency:MANual on page 465.
STEP
Each trigger command triggers one sweep step only.
The frequency increases by the value set with the coammnds:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP[:
LINear] (linear spacing)
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP:
LOGarithmic(logarithmic spacing)
*RST:
AUTO
Example: See Example"Setup an LF sweep" on page 461.
Manual operation: See "Mode" on page 130
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:POINts <Points>
Sets the number of steps in an LF sweep.
For information on how the value is calculated and the interdependency with other
parameters, see Chapter 6.2.1, "Correlating parameters in sweep mode", on page 122
Parameters:
<Points> integer
Range: 2 to POINts
*RST: 50
Example: See Example"Setup an LF sweep" on page 461.
[:SOURce<hw>]:LFOutput: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".
