freq_points = ((log f
STOP
- log f
STARt
) / log step_log) + 1
To determine the logarithmic step size, use the command SWE:STEP:LOG .
If you change the number of sweep points, the step size changes accordingly. The
sweep range remains the same.
Each sweep spacing mode has assigned the
POINts
setting separately. Thus, the
command refers always to the particular set mode, see
[:SOURce<hw>]:LFOutput:
SWEep[:FREQuency]:SPACing
.
Parameters:
<Points> integer
Range:
2...max
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<hw>]:LFOutput:SWEep[:FREQuency]:RUNNing?
Queries the current status of the LF frequency sweep mode.
Return values:
<State> 0 | 1 | OFF | ON
Example: LFO:SWE:RUNN?
Response
"1"
: the frequency sweep is running.
Usage: Query only
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:SHAPe <Shape>
Sets the cycle mode for a sweep sequence (shape).
Parameters:
<Shape> SAWTooth | TRIangle
SAWTooth
A sweep runs from the start to the stop frequency. A subsequent
sweep starts at the start frequency, that menas the shape of the
sweep sequence resembles a sawtooth.
TRIangle
A sweep runs from the start to the stop frequency and back,
thatnt menas the shape of the sweep resembles a triangle. A
subsequent sweep starts at the start frequency.
