Alternatively, you can create customized calibration kits with the functionality of the
R&S InstrumentView software package and transfer those to the R&S
ZNH.
To successfully calibrate the test setup, you have to connect the calibration standard at
the reference plane, usually the output of the RF measurement cable.
Before you calibrate the R&S
ZNH for the current measurement, you should set the
frequency parameters, reference level, measurement bandwidth and attenuation lev-
els. If you change one of these parameters after a successful calibration, it may
become invalid.
During calibration, the R&S
ZNH removes systematic errors from the measurement.
This process is based on correction data it gets while performing the calibration.
The correction data for transmission measurements is based on the results of compar-
ing the transmission characteristics of the test setup to the frequency response of the
tracking generator. The correction data for reflection measurements is based on the
results of a reflection measurement at a short and an open on the bridge.
Calibration remains valid after turning off the R&S
ZNH or changing into another oper-
ating mode as calibration data is saved in the internal memory of the R&S
ZNH. If you
save the measurement in a dataset, calibration data is part of that dataset. When you
restore the dataset and perform the same measurement again, you do not have to
recalibrate the R&S
ZNH.
