Note: If the stop frequency entered is smaller than the current start frequency
(CA
LCulate<Chn>:TRANsform:TIME:STARt), the start frequency is set to the stop frequency
minus the minimum frequency span (CALCulate<Chn>:TRANsform:TIME:SPAN).
If the x-axis is scaled in distance units (CALCulate<Chn>:TRANsform:TIME:XAXis
DISTance), then the stop value is entered in m; the range and default value changes accordingly.
CALCulate<Chn>:TRANsform:TIME[:TYPE] BPASs | LPASs
Selects the time domain transformation type.
<Chn>
Channel number used to identify the active trace
Parameters
BPASs – Band pass impulse (only impulse response; a step response
CALCulate<Chn>:TRANsform:TIME:STIMulus STEP is automatically
changed to impulse response)
LPASs – Low pass (impulse or step response, depending on
CALCulate<Chn>:TRANsform:TIME:STIMulus setting)
*RST value BPASs
SCPI,
Command
Types
Confirmed, command or query
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.
CALCulate<Chn>:TRANsform:TIME:WINDow RECT | HAMMing | HANN | BOHMan |
DCHebyshev
Selects the window type for filtering the data in the frequency domain prior to the time domain
transformation.
<Chn>
Channel number used to identify the active trace
Parameters
RECT – No profiling (rectangle)
HANN – Normal profile (Hann)
HAMMing – Low first sidelobe (Hamming)
BOHMan – Steep falloff (Bohman)
DCHebyshev – Arbitrary sidelobes (Dolph-Chebychev)
*RST value HANN
SCPI, Command Types
Confirmed (with some device-specific parameters), command or query
