●
For filter measurements requiring high standards (for example S11 in passband
better than -20 dB), use the full 2-port calibration.
●
For full S-parameter measurements on attenuators or amplifiers, use the full 2-port
calibration.
8.1.3 Performing Calibration
●
A successful calibration supersedes the previous calibration, discarding all previ-
ous system error correction data.
The procedure is similar for all calibration methods, except that you are going to need
different type and number of calibration standards.
1. Disconnect the DUT from the RF cable.
After disconnecting the DUT, the R&S ZNH is ready for calibration.
2. Press [CAL] key.
3. Select "Cal Config" softkey.
The R&S ZNH displays the Calibration configuration dialog .
4. Select the "Ports" ("Port1" and/or "Port2") to define the port assignments between
the R&S ZNH and the calibration unit.
The R&S ZNH extracts the "Connector" type and "Gender" of the connector from
"Calibration Kit" file.
5. Select the calibration "Type" to perform the calibration standard.
For more information, see Chapter 8.1.2, "Calibration Methods" , on page 149.
6. Select the calibration kit to load the required calibration file from the file manager.
For a list of supported calibration kits, see Chapter 7.1.7.3, "Calibration Kit" ,
on page 122.
7. Select "Apply" to save the calibration configuration.
The R&S ZNH displays the Chapter 4.1.4, "Measurement Trace Window" ,
on page 32.
If the calibration configuration is incompatible for the selected "Ports" and calibra-
tion "Type" settings, the R&S
ZNH displays an invalid message.
8. Select "Calibrate" softkey to proceed the user calibration.
The R&S ZNH displays the saved "Calibration Configuration" message box.
