[SENSe<Ch>:]CORRection:DATE?
Returns the date and time when the active system error correction data for channel
<Ch>
was acquired (see example).
Suffix:
<Ch>
.
Channel number of the calibrated channel
Example:
CORR:COLL:METH REFL1
Select a one-port normalization at port 1 as calibration type.
CORR:COLL OPEN1
Measure an open standard connected to port 1 and store the
measurement results of this standard.
CORR:COLL:SAVE
Calculate the system error correction data and apply it to the
active channel.
CORR:DATE?
Query the time when the system error correction became active.
The analyzer returns the date and time, e.g.
'03/20/11,18:30:39'
.
CORR:DATA:PAR?
Query the sweep settings for the calibration sweep. The ana-
lyzer returns the start and stop frequency, the number of points,
source power, and the sweep type, e.g.
300000,8000000000,201,0,LIN
.
CORR:SST?
Query the calibration status. The analyzer returns
'CAL OFF'
(because the performed one-port calibration is not sufficient for
the measured transmission S-parameter S
21
).
Usage:
Query only
Manual operation:
[SENSe<Ch>:]CORRection:EDELay<PhyPt>:AUTO
<Activate>
Defines the offset parameter for the active test port such that the residual delay of the
active trace (defined as the negative derivative of the phase response) is minimized
across the entire sweep range ("Auto Length").
Suffix:
<Ch>
.
Channel number of the offset-corrected channel
<PhyPt>
Port number of the analyzer. This numeric suffix is ignored; the
active port is determined by the active trace.
Setting parameters:
<Activate>
ONCE
Applies the auto length function.
Example:
*RST; :CORR:EDEL:AUTO ONCE
Reset the instrument and apply the auto length function to the
default trace (Trc1 in channel 1).
