[:SOURce]:LFOutput:FREQuency:STOP <Stop>
This command sets the stop frequency for the LF sweep.
Parameters:
<Stop> float
Range: 0.1 Hz to 1 MHz
Increment: 0.1 Hz
*RST: 50 kHz
Example:
LFO:FREQ:STOP 200 kHz
sets the stop frequency for the LF sweep to 200 kHz.
LFO:FREQ:STAR 100 kHz
sets the start frequency for the LF sweep to 100 kHz.
[:SOURce]:LFOutput[:STATe] <State>
The command activates/deactivates the LF output.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: OFF
Example:
LFO ON
activates the LF output. The settings under LFO:FREQ and
LFO:SWE become effective.
[:SOURce]:LFOutput:SWEep[:FREQuency]:DWELl <Dwell>
The command sets the dwell time for each frequency step of the sweep.
Tip: It is recommended to switch off the "GUI Update" for optimum sweep performance
especially with short dwell times (SYSTem:DISPlay:UPDate OFF).
Parameters:
<Dwell> float
Range: 10.0E-3 to 100
Increment: 100.0E-6
*RST: 10.0E-3
Default unit: s
Example:
LFO:SWE:DWEL 20 ms
sets a dwell time of 20 ms.
[:SOURce]:LFOutput:SWEep[:FREQuency]:EXECute
The command immediately starts an LF sweep.
The MODE setting ([:SOURce]:LFOutput:SWEep[:FREQuency]:MODE) deter-
mines which sweep is executed, e.g. SOURce:LFOutput:SWEep:FREQuency:MODE
STEP.
