[:SOURce]:LFOutput:SWEep[:FREQuency]:POINts <Points>
The command sets the number of steps in an LF sweep.
The command is linked to the command :LFOutput:SWEep[:FREQuency]:STEP as
follows:
●
for linear sweeps and STARt < STOP
POINts = ((STOP-STARt) / STEP:LIN) + 1
●
for logarithmic sweeps and STARt < STOP
POINts = ((log STOP - log STARt) / log STEP:LOG) + 1
If POINTs changes, the value of STEP is adjusted. The STARt and STOP value is retained.
Two separate POINts values are used for linear or logarithmic sweep spacing
(LFOutput:SWEep[:FREQuency]:SPACing LIN | LOG). The command is always
effective for the currently set sweep spacing.
Parameters:
<Points> float
Increment: 1
*RST: 100
Example:
LFO:FREQ:STAR
sets the start frequency to 2 kHz.
LFO:FREQ:STOP
sets the stop frequency to 20 kHz
LFO:SWE:SPAC LIN
sets linear sweep spacing.
LFO:SWE:POIN 11
sets 11 sweep steps for linear sweep spacing. The sweep step
width (STEP) is automatically set to 2 kHz.
[:SOURce]:LFOutput:SWEep[:FREQuency]:RUNNing?
Queries the status of the LF frequency sweep.
Return values:
<State> 0 | 1 | OFF | ON
Example:
LFO:SWE:RUNN?
Response "1": the frequency sweep is running.
Usage: Query only
[:SOURce]:LFOutput:SWEep[:FREQuency]:SHAPe <Shape>
The command sets the cycle mode for a sweep sequence (shape).
