To take control of the converter input and output levels, proceed as follows:
1. At the graphical user interface of the R&S
ZNA, run the scalar power calibra-
tion wizard (Channel – [Cal] key > "Start Cal" tab > "Scalar Power Cal ...")
2. On the first page of the wizard, you can perform source flatness calibrations at
the converter inputs.
Perform a source flatness calibration, if the configured values for cable and
splitter losses cannot describe the actual ones with sufficient accuracy (sum
deviation > 2
.
3. The second page of the wizard offers several calibration types:
a) "Ref. Receiver"
To perform a reference receiver calibration, connect a power meter with
suitable frequency range to the 1
mm port of the respective external test
set. During the calibration, the R&S
ZNA performs a frequency sweep and
uses the power meter readings to correct the readings of the related refer-
ence receiver (transfer calibration). We recommend using the
Rohde&Schwarz thermal power meter R&S
NRP110T.
With the default power calibration method of the R&S
ZNA, subsequent
measurement receiver and source flatness calibrations rely on an existing
reference receiver calibration. For output power leveling, an existing refer-
ence receiver calibration of the respective port is a prerequisite.
Scalar power calibration and leveling (optional)
