Note: If the stop frequency entered is smaller than the current start frequency (
), the start frequency is set to the stop
frequency minus the minimum frequency span (
). If the x-axis is scaled in distance units (
DISTance
), then the stop value is entered in m; the range
and default value changes accordingly.
CALCulate<Chn>:TRANsform:TIME[:TYPE]
<TransformType>
Selects the time domain transformation type.
Suffix:
<Chn>
.
Channel number used to identify the active trace.
Parameters:
<TransformType>
BPASs | LPASs
BPASs - band pass impulse (only impulse response; a step
response

Example:
*RST; :CALC:TRAN:TIME:STAT ON
Reset the instrument, activating a frequency sweep, and enable
the time domain transformation for the default trace.
CALC:TRAN:TIME LPAS; TIME:STIM STEP
Select a low pass step transformation.
CALC:TRAN:TIME:LPAS KFST
Calculate a harmonic grid, keeping the stop frequency and the
number of points.
Manual operation:
