This subsystem defines the properties of the time gate which is used to optimize the time domain response (with option ZVAB-K2, Time Domain).
Command tree: CALCulate<Chn>:FILTer[:GATE]
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: |
Reset the instrument and enable the time domain representation and the time gate.
|
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: |
Reset the instrument and select a Dolph-Chebyshev time gate for filtering the data in the frequency domain.
|
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) |
*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.
|
Enables or disables permanent display of the gate limits.
<Chn> |
Channel number used to identify the active trace
|
<Boolean> |
ON –
Time gate permanently displayed |
*RST value |
OFF [–]
|
SCPI, Command Types |
Device-specific, command or query
|
Example: |
|
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: |
|
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: |
Reset the instrument and enable the time domain representation and the time gate.
|
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).
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 |
*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.
|
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).
Selects the time gate filter type, defining what occurs to the data in the specific time region.
<Chn> |

all else |
*RST value |
