CALCulate<Chn>:FILTer[:GATE]:TIME:CENTer <numeric_value>

Defines the center time of the time gate.

<Chn>	Channel number used to identify the active trace
<numeric_value>	Center time of the time gate
Range [def. unit]	-99.8999999 s to +99.8999999 s. The increment (parameters UP or DOWN) is 0.1 ns. [s]
*RST value	1.5E-009 s
SCPI, Command Types	Confirmed, command or query
Example:	`*RST; :CALC:TRAN:TIME:STAT ON; :CALC:FILT:TIME:STAT ON` Reset the instrument and enable the time domain representation and the time gate. `CALC:FILT:TIME:CENT 0; SPAN 5ns` `S`et the center time to 0 ns and the time span to 5 ns.

CALCulate<Chn>:FILTer[:GATE]:TIME:DCHebyshev <numeric_value>

Sets the sideband suppression for the Dolph-Chebyshev time gate. The command is only available if a Dolph-Chebyshev time gate is active (CALCulate<Chn>:FILTer[:GATE]:TIME:WINDow DCHebyshev).

<Chn>	Channel number used to identify the active trace
<numeric_value>	Sideband suppression
Range [def. unit]	10 dB to 120 dB. The increment (parameters UP or DOWN) is 10 dB. [dB]
*RST value	32 dB
SCPI, Command Types	Device-specific, command or query
Example:	`*RST; :CALC:FILT:TIME:WIND DCH` Reset the instrument and select a Dolph-Chebyshev time gate for filtering the data in the frequency domain. `CALC:FILT:TIME:DCH 25` `S`et the sideband suppression to 25 dB.

CALCulate<Chn>:FILTer[:GATE]:TIME:SHAPe
MAXimum | WIDE | NORMal | MINimum

Selects the time gate to be applied to the time domain transform.

Use the generalized command CALCulate<Chn>:FILTer[:GATE]:TIME:WINDow if you wish to select a Dolph-Chebychev time gate.

<Chn>	Channel number used to identify the active trace
Parameters	MINimum – Steepest edges (rectangle) WIDE – Normal gate (Hann) NORM – Steep edges (Hamming) Maximum – Maximum flatness (Bohman)
*RST value	WIDE
SCPI, Command Types	Device-specific, command or query
Example:	*RST; :CALC:FILT:TIME:SHAP? Reset the instrument and query the type of time gate used. The response is WIDE.

CALCulate<Chn>:FILTer[:GATE]:TIME:SHOW <Boolean>

Enables or disables permanent display of the gate limits.

<Chn>	Channel number used to identify the active trace
<Boolean>	ON – Time gate permanently displayed OFF – Time gate hidden
*RST value	OFF [–]
SCPI, Command Types	Device-specific, command or query
Example:	`See CALCulate<Chn>:FILTer[:GATE]:TIME:CENTer`

CALCulate<Chn>:FILTer[:GATE]:TIME:SPAN <span>

Defines the span of the time gate.

<Chn>	Channel number used to identify the active trace
<span>	Span of the time gate.
Range [def. unit]	2E-012 s to 200 s. The increment (parameters UP or DOWN) is 0.1 ns. [s]
*RST value	5E-009 s
SCPI, Command Types	Confirmed, command or query
Example:	`See CALCulate<Chn>:FILTer[:GATE]:TIME:CENTer`

CALCulate<Chn>:FILTer[:GATE]:TIME:STARt <start>

Defines the start time of the time gate.

<Chn>	Channel number used to identify the active trace
<start>	Start time of the time gate.
Range [def. unit]	–100 s to +99.999999999998 s. The increment (parameters UP or DOWN) is 0.1 ns. [s]
*RST value	–1E-009 s
SCPI, Command Types	Confirmed, command or query
Example:	`*RST; :CALC:TRAN:TIME:STAT ON; :CALC:FILT:TIME:STAT ON` Reset the instrument and enable the time domain representation and the time gate. `CALC:FILT:TIME:STAR 0; STOP 10ns; SHOW ON` `S`et the start time to 0 ns and the stop time to 10 ns and display the time gate permanently.

Note: If the start frequency entered is greater than the current stop frequency (CALCulate<Chn>:FILTer[:GATE]:TIME:STOP), the stop frequency is set to the start frequency plus the minimum frequency span (CALCulate<Chn>:FILTer[:GATE]:TIME:SPAN).

CALCulate<Chn>:FILTer[:GATE]:TIME:STATe <Boolean>

Determines whether the time gate for trace no. <Chn> is enabled.

<Chn>	Channel number used to identify the active trace
<Boolean>	ON – Time gate enabled OFF – Time gate disabled
*RST value	OFF [–]
SCPI, Command Types	Confirmed, command or query
Example:	RST; :CALC:TRAN:TIME:STAT?; :CALC:FILT:TIME:STAT? Reset the instrument, activating a frequency sweep, and query whether the default trace is displayed in the time domain and whether the time gate is enabled. The response is 0;0*.

CALCulate<Chn>:FILTer[:GATE]:TIME:STOP <numeric_value>

Defines the stop time of the time gate.

<Chn>	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<Chn>:FILTer[:GATE]:TIME:STARt.

Note: If the stop frequency entered is smaller than the current start frequency (CALCulate<Chn>:FILTer[:GATE]:TIME:STARt), the start frequency is set to the stop frequency minus the minimum frequency span (CALCulate<Chn>:FILTer[:GATE]:TIME:SPAN).

CALCulate<Chn>:FILTer[:GATE]:TIME[:TYPE]
BPASs | NOTCh

Selects the time gate filter type, defining what occurs to the data in the specific time region.

<Chn>	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.
