CALCulate<Ch/Tr>:TRANsform:TIME:CENTer <numeric_value>
Defines the center time of the diagram in time domain.
<Ch/Tr> Channel number used to identify the active trace
<numeric_value> Center time of the diagram in time domain
Range [def. unit] -99.99999999999 s to +99.99999999999 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
Reset the instrument, activating a frequency sweep, and enable
the time domain transformation for the default trace.
CALC:TRAN:TIME:CENT 0; SPAN 5ns
S
et the center time to 0 ns and the time span to 5 ns.
Note: If the x-axis is scaled in distance units (
CALCulate<Ch/Tr>:TRANsform:TIME:XAXis
DISTance
), then the center value is entered in m; the range and default value changes
accordingly.
CALCulate<Ch/Tr>:TRANsform:TIME:DCHebyshev <numeric_value>
Sets the sideband suppression for the Dolph-Chebyshev window. The command is only available if a
Dolph-Chebyshev window is active (
CALCulate<Ch/Tr>:TRANsform: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:TRAN:TIME:WIND DCH
Reset the instrument and select a Dolph-Chebyshev window for
filtering the data in the frequency domain.
CALC:TRAN:TIME:DCH 25
S
et the sideband suppression to 25 dB.
CALCulate<Ch/Tr>:TRANsform:TIME:LPASs KFSTop | KDFRequency |
KSDFRequency
Calculates the harmonic grid for low pass time domain transforms according to one of the three
alternative algorithms.
