CALCulate<Ch/Tr>: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<Ch/Tr>:FILTer[:GATE]:TIME:WINDow
DCHebyshev).
<Ch/Tr>
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
Set the sideband suppression to 25 dB.
CALCulate<Ch/Tr>: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<Ch/Tr>:FILTer[:GATE]:TIME:WINDow if you
wish to select a Dolph-Chebychev time gate.
<Ch/Tr>
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<Ch/Tr>:FILTer[:GATE]:TIME:SPAN <numeric_value>
Defines the span of the time gate.
<Ch/Tr>
Channel number used to identify the active trace
<numeric_value>
Span of the time gate.
