This subsystem defines the transmission coefficients for an additional two-port in the test setup (power loss list)).
Command tree: SOURce<Ch>POWer<Pt>:CORRection:TCOefficient
Selects the position of the additional two-port in the test setup.
|
<Ch> |
Calibrated channel number. This parameter is ignored; the transmission coefficient settings are valid for all channels.
|
|
<Pt> |
Calibrated port number. This parameter is ignored; the transmission coefficient settings are valid for all sources.

Example: |
*RST; :SOUR:POW:CORR:TCO:CAL OFF Select the test setup with the additional two-port in front of the DUT. SOUR:POW:CORR:TCO:DEF 1GHz, -5; DEF 2GHz, -10; DEF2? Define two points in the power loss list; query the second point. SOUR:POW:CORR:TCO:INS2 1.5 GHz, -7.5 Insert a third point as point no. 2 in the list. SOUR:POW:CORR:TCO:COUN? Query the number of points. The response is 3. SOUR:POW:CORR:TCO ON Enable the use of two-port transmission coefficients. SOUR:POW:CORR:TCO:FEED 'Trc1' Replace the previous 3 points by the trace points of the default trace 'Trc1'. MMEM:STOR:CORR:TCO 'C:\Rohde&Schwarz\NWA\PowermeterCorrLists\Test.pmcl' Store the power loss list to the power meter correction list file Test.pmcl in the directory C:\Rohde&Schwarz\NWA\PowermeterCorrLists. MMEM:LOAD:CORR:TCO 'C:\Rohde&Schwarz\NWA\PowermeterCorrLists\Test.pmcl' Re-load the stored power meter correction list file. SOUR:POW:CORR:TCO:DEL1 Delete the first point in the list. SOUR:POW:CORR:TCO:DEL:ALL; :SOUR:POW:CORR:TCO? Clear the entire list. Query whether the transmission coefficients are still taken into account. The response is 0. MMEM:LOAD:CORR:TCO 'C:\Rohde&Schwarz\NWA\Traces\Test.s2p', 'S21' Load a power loss list from a previously created 2-port Touchstone file. .

Queries the number of frequency values and transmission coefficients in the power loss list.
Adds a new frequency and transmission coefficient to the end of the power loss list.
|
<Ch> |
Calibrated channel number. This parameter is ignored; the transmission coefficient settings are valid for all channels.
|
|
<Pt> |
Calibrated port number. This parameter is ignored; the transmission coefficient settings are valid for all sources.
|
|
<List_no> |
Number of point in the list. This suffix is only used for queries. |
|
<frequency> |
Stimulus frequency value |
|
Range [def. unit] |
According to frequency range of the analyzer; see list of analyzer models [Hz]. If several points with identical frequencies are added, the analyzer automatically ensures a frequency spacing of 1 Hz. |

Transmission coefficient |
|
Range [def. unit] |
–300 dB to +200 dB [dB] |

Enables or disables the use of two-port transmission coefficients.
The power loss list must contain at least
one point before the transmission coefficients can be enabled.
