CALCulate<Ch/Tr>:FILTer[:GATE]:TIME:STOP <numeric_value>
Defines the stop time of the time gate.
<Ch/Tr> Channel number used to identify the active trace
<numeric_value> Stop time of the time gate.
Range [def. unit] –99.999999999998 s to +100 s. The increment (parameters UP
or DOWN) is 0.1 ns. [s]
*RST value +4E-009 s
SCPI, Command
Types Confirmed, command or query
Example:
See CALCulate<Ch/Tr>:FILTer[:GATE]:TIME:STARt.
Note: If the stop frequency entered is smaller than the current start frequency
(
CALCulate<Ch/Tr>:FILTer[:GATE]:TIME:STARt
), the start frequency is set to the stop
frequency minus the minimum frequency span
(
CALCulate<Ch/Tr>:FILTer[:GATE]:TIME:SPAN
).
CALCulate<Ch/Tr>:FILTer[:GATE]:TIME[:TYPE] BPASs | NOTCh
Selects the time gate filter type, defining what occurs to the data in the specific time region.
<Ch/Tr> Channel number used to identify the active trace
Parameters
BPASs – Band pass filter: pass all information in specified time
region and reject all else
NOTCh – Notch filter: reject all information in specified time
region and pass all else.
*RST value BPASs
SCPI, Command
Types Confirmed, command or query
Example:
*RST; CALC:FILT:TIME:STAT ON
Reset the instrument and enable the time gate.
CALC:FILT:TIME NOTCh
Select a notch filter in order to reject unwanted pulses.
CALCulate<Ch/Tr>:FILTer[:GATE]:TIME:WINDow RECT | HAMMing | HANN |
BOHMan | DCHebyshev
Selects the time gate to be applied to the time domain transform.
<Ch/Tr> Channel number used to identify the active trace
Parameters RECT – Steepest edges (rectangle)
HANN – Normal gate (Hann)
HAMMing – Steep edges (Hamming)
BOHMan – Minimum flatness (Bohman)
DCHebyshev – Arbitrary gate shape (Dolph-Chebychev)
*RST value HANN
