Page 27: Configuration And Measurement Steps
® Basic operation R&S ZCxxx Configuring the converter setup Configuration and measurement steps Follow the connection sequence described in Chapter 5.1, "Connection pro- cedure", on page 22. Configuring the measurement setup and measuring the DUT involves the follow- ing steps: 1. - Page 28 ® Basic operation R&S ZCxxx Configuring the converter setup "Converter 1" is the converter connected to VNA port 1, "Converter 2" the con- verter connected to VNA port 2. 2. In the "Converter Configuration" dialog, verify that your R&S ZNA has regis- tered your converters.
- Page 29 ® Basic operation R&S ZCxxx Configuring the converter setup Figure 6-1: Standard setup with two converters 4. Select "OK" to apply the converter configuration and close the dialog. The R&S ZNA now adjusts the frequencies and source power levels. The fre- quencies correspond to the maximum frequency range of the configured con- verters, the source power levels also take the cable and splitter losses into account.

® Basic operation R&S ZCxxx Scalar power calibration and leveling (optional) The resulting frequency and source power levels can be viewed – and tweaked – in the port settings dialog (Channel – [Channel Config] key > "Port Config" tab > "Port Settings ..."). For details, see the R&S ZNA help system or user manual. - Page 31 ® Basic operation R&S ZCxxx Scalar power calibration and leveling (optional) Perform a source flatness calibration, if the default values for cable and split- ter losses deviate significantly from the actual ones (sum deviation > 2 dB). step 5 Chapter 6.3, "Configuring the converter setup", on page 27.
- Page 32 ® Basic operation R&S ZCxxx Scalar power calibration and leveling (optional) b) "Meas. Receiver" A measurement receiver calibration adjusts the power readings at the receive port, by default based on an existing reference receiver calibration. With an existing reference receiver calibration for port 1, to calibrate the measurement receiver of port 1, connect a Short to the waveguide port of converter 1 and select port 1 as source.
- Page 33 ® Basic operation R&S ZCxxx Scalar power calibration and leveling (optional) c) "Leveling Table (Global)" Perform leveling if you want the power levels at the waveguide port to be constant over frequency. Also perform leveling if you want to have fre- quency-independent, variable, known power levels at the waveguide port.
