Page 41: Required Equipment
® Basic operation R&S ZNA67EXT Converter configuration Required equipment The cabling of the external test sets is described in Chapter 8, "Connecting the external test sets", on page 33. To calibrate the measurement setup, the following equipment is required: ● For power calibration and leveling at the 1 mm port of the external test set, a power meter that covers the measured frequency range, such as the thermal power sensor R&S NRP110T. - Page 42 2. In the "Converter Configuration" dialog, configure the standard setup with two converters: a) For both converter ports, set "Converter Type" to "ZNA67EXT-TS" The firmware automatically fixes "IF Input" to "Rear & Dir" (rear IF access for high, direct access for low frequencies).
- Page 43 ® Basic operation R&S ZNA67EXT Scalar power calibration and leveling (optional) Cable and splitter losses Check the cable and splitter losses: 1. Open the "Default Cable and Splitter Losses" dialog (System – [Setup] key > "Frequency Converter" tab > "Default Cable and Splitter Losses ...").
- Page 44 ® Basic operation R&S ZNA67EXT Scalar power calibration and leveling (optional) 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.
- Page 45 ® Basic operation R&S ZNA67EXT 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 an Open to the 1 mm port of con- verter 1 and select port 1 as source.
- Page 46 ® Basic operation R&S ZNA67EXT 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 absolute power levels at the wave- guide port.
- Page 47 System error correction requires a calibration kit that is suitable for the mea- sured frequency range. For the R&S ZNA67EXT we recommend the 1 mm cali- bration kit R&S ZV-Z210. The standards in these calibration kits allow for OSM, TOSM, UOSM and TOM calibrations.
