Increasing (decreasing) the values in the correction data sets increases (decreases)
the input power reading. Writing correction data (the setting command) fails if the num-
ber of transferred values is not equal to the number of sweep points.
Suffix:
<Ch>
.
Calibrated channel number
<PhyPt> Physical port number, used to select a specific frequency axis in
arbitrary mode (with option R&S ZNB/ZNBT-K4).
Parameters:
<Wave> Identifier for the calibrated wave:
'A<n>' or 'AWAV<n>' denote correction data for the reference
wave a<n>, where <n> corresponds to the port number.
'B<n>' or 'BWAV<n>' denote correction data for the reference
wave b<n>.
<CorrData> Power correction values either in ASCII or block data format,
depending on the current FORMat[:DATA] setting.
Example:
*RST; :SWE:POIN 10
Reset the instrument and reduce the number of sweep points to
10.
CORR:POW:ACQ AWAVe,1,PORT,1
Perform a receiver power calibration of the wave a
1
using port 1
as a source port, assuming that the transmitted source power a
1
is correct. No external cabling is needed.
CORR:POW:DATA? 'AWAV1'
Query the correction values. The analyzer returns 10 comma-
separated real numbers.
CORR:POW:DATA 'AWAV1', 1, 2, 3, 4, 5, -6, -7,
-8, -9, -0
Replace the correction values by ten (new) numbers.
Manual operation:
See "Start Cal Sweep" on page 481
[SENSe<Ch>:]CORRection:POWer<PhyPt>:IMODulation:ACQuire
[<CalOnlyPortFreq>]
Starts the receiver calibration (3
rd
power calibration step for intermodulation measure-
ments), stores and applies the calibration data.
Note: The receiver calibration relies on the source power calibration acquired in step
nos. 1 and 2.
[SENSe<Ch>:]CORRection:POWer<PhyPt>:IMODulation:ACQuire is enabled
only after steps 1 and 2 have been carried out (SOURce<Ch>:POWer<PhyPt>:
CORRection:IMODulation:LTONe[:ACQuire], SOURce<Ch>:POWer<PhyPt>:
CORRection:IMODulation:UTONe[:ACQuire]).
