Full 1-Port ("Refl OSM")
RF input port is calibrated for measurements on that port. The calibration routine
requires the calibration standards open, short and load to be connected one after
another.
For more information on "Refl OSM" , see
Chapter 8.1.2, "Calibration Methods"
●
One port normalize ("Refl Norm Open" and "Refl Norm Short")
RF input port is calibrated for measurement on that port. The calibration procedure
requires no calibration standards for "Refl Norm Open" calibration as the R&S
ZNH
calibrates an open connection only. See
Chapter 8.1.2, "Calibration Methods"
on page 149 for more information on "Refl Norm Open" and "Refl Norm Short".
●
Normalize Trans ("Trans Norm P1", "Trans Norm P2" and "Trans Norm Both")
Both RF ports are calibrated for transmission measurements. The calibration rou-
tine requires only a Through connection. In the subsequent measurement, the iso-
lation between the test ports is not taken into account, a possible cross-talk
between the test ports in the test setup is not eliminated.
See
Chapter 8.1.2, "Calibration Methods"
on page 149 for more information on
"Trans Norm P1", "Trans Norm P2" and "Trans Norm Both".
User calibration
After a user calibration is performed, the R&S
ZNH allows you the option to apply user
calibration ("cal" or "norm") or resume factory calibration data on the measurement.
1. Press the [CAL] key.
2. Select the "User Calibration" softkey.
Depending on the current calibration state, the R&S
ZNH toggles between the user
calibration and factory calibration state.

hand corner of the trace window.

Calibration Kit
The calibration kit model provides the "Open", "Short", and "Load" parameters that are
to be taken into consideration when performing a calibration with the corresponding
calibration kit. The R&S
ZNH supports the following calibration models:
●
R&S FSH-Z28
●
R&S FSH-Z29
●
R&S ZCAN
●
R&S ZV-Z121 Male / Female
●
R&S ZV-Z132 Male / Female
●
R&S ZV-Z135 Male / Female
●
R&S ZV-Z170 Male / Female
Alternatively, you can create customized calibration kits with the functionality of R&S
InstrumentView software package and use them on the R&S
ZNH. For more informa-
