R&S SMB100A
This parameter always applies to the currently set sweep spacing and correlates with
the step size as follows:
●
for linear sweeps and f
freq_points = (f
with f
To determine the step size, use the command SWE:STEP[:LIN].
●
logarithmic sweeps and f
freq_points = ((log f
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
SWEep[:FREQuency]:SPACing.
Parameters:
<Points>
Example:
[: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".
Parameters:
