R&S NRP-Z11/21/31/41/61/211/221 Program module "Update S-Parameters"
1137.7470.12 3.9 E-7
Procedure
T
o load an s-parameter table into the calibration set of the sensor, proceed as follows:
1. Connect the sensor to the USB port of the PC and start the program module Update S-
Parameters. The corresponding dialog window is opened (Fig. 3-3).
2
. Make sure Keep Current S-Parameter Data is deactivated.
3. Under S-Parameter File enter the search path and the name of the S2P file containing the
parameters. Press the Browse... button to open a file-opening dialog where the S2P measurement
data file can be easily selected.
4. Under Uncertainty File enter the search path and the name of the measurement uncertainty file
containing the measurement uncertainty of the s-parameter test system. Press the Browse...
button to open a file-opening dialog where the measurement uncertainty file can be easily selected.
5. Enter the upper and lower nominal measurement limit of the sensor-twoport combination in the
Lower Power Limit and Upper Power Limit fields.
6. Enter a name for the loaded s-parameter set in the S-Parameter Device Mnemonic field. This
name can later be queried with SYSTem:INFO? "SPD Mnemonic" and is displayed on the NRP
basic unit when s-parameter correction is switched on.
7. Activate S-Parameter Correction on by Default if the SENSe:CORRection:SPDevice:STATe
switch should be automatically set to ON when the sensor is put into operation.
8. Designations for calibration laboratory and person responsible for calibration may be entered in the
Calibration Lab and Calibration Engineer fields. These designations are stored in the calibration
data set. They are implicitly set to „user lab“ and „user“, respectively, if the fields are left blank.
9. Press Start for loading. (The dialog is closed with OK and the set parameters are retained. When
the dialog is exited with Cancel, all parameter modifications are ignored.)
