6.1 Calibrating Measurements
In its default state, the R&S ZVH uses factory calibration. Factory calibration is a full 2-
port calibration over the complete frequency range of the R&S ZVH model. When
factory calibration is active, the status line reads
. In many cases, this calibration
already provides accurate results.
To get the best and most accurate results, however, you have to calibrate the
measurement manually, because factory calibration does not take the actual test setup
into account (e.g. cables). The R&S ZVH provides several calibration methods. You
will need one of the available calibration standards R&S FSH-Z28, -Z29 (order no.
1300.7804.03 and 1300.7504.03) or R&S ZV-Z121 (order no. 1164.0496.02/.03).
Alternatively, you can create customized calibration kits with the functionality of the
R&S ZVHView software package and transfer those to the R&S ZVH.
Before you calibrate the R&S ZVH for the current measurement, you should set the
frequency parameters, reference level and attenuation levels. If you change one of
these parameters after a successful calibration, it may become invalid.
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.
During calibration, the R&S ZVH 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
comparing 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 ZVH or changing into another
operating mode as calibration data is saved in the internal memory of the R&S ZVH. 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 ZVH.
