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 calibration
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 dB). See step 2 in step 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 suita-
ble 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 reference receiver (trans-
fer 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 mea-
surement receiver and source flatness calibrations rely on an existing reference
receiver calibration. For output power leveling, an existing reference receiver
calibration of the respective port is a prerequisite.
