[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:MODE <Mode>

Sets the cycle mode of the LF sweep.

The assignment of the GPIB commands to the sweep modes is given in the description of the sweep dialogs.

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 deterrmines the time period for the signal to switch to the next step.

MANual

Performs a single sweep step when a manual trigger event occurs.

The trigger system is not active. You can trigger each frequency step of the sweep individually with the command [:SOURce<hw>]:LFOutput:FREQuency:MANual. In manual mode, use the rotary knob for switching to the next step.

With each step, the frequency increases by the value specified with the command [:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] or [:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic, respectively. A frequency value, entered with [:SOURce<hw>]:LFOutput:FREQuency:MANual takes no effect.

With manual control, the frequency increases or decreases (depending on the direction of the rotary encoder) by the value specified under SOUR:LFO:SWE:FREQ:STEP:LIN (linear spacing) or ...:STEP:LOG (logarithmic spacing).

STEP

Each trigger triggers one sweep step only. The frequency increases by the value entered with [:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] or [:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic.

*RST:AUTO
Example: LFO:SWE:MODE AUTO

selects Auto mode.
