102User Manual 1178.6462.02 ─ 29
The R&S ZNA now sets the involved ports to their maximum frequency range
(10 MHz to 110 GHz). It sets the related receiver step attenuators to 0 dB, activates
low phase noise mode and deactivates automatic level control. In addition, the
firmware adjusts the source power levels according to the properties of the "Rear &
Dir" signal paths and the configured cable and splitter losses.
Converter configurations can be saved and loaded via the graphical user interface of
the R&S ZNA.
("Save Converter Topology..."/"Load Converter Topology..." on the Frequency Con-
verter tab)
Cable and splitter losses
Check the cable and splitter losses:
1. Open the "Default Cable and Splitter Losses" dialog (System – [Setup] key > "Fre-
quency Converter" tab > "Default Cable and Splitter Losses ...").
2. Adjust "Cable & Splitter Loss" and "Slope", if your cables and splitter losses deviate
significantly from the default settings, which fit for cable sets R&S ZCASGO.
3. Select "OK" to apply your settings and close the dialog.
The resulting frequency and source power levels can be viewed – and tweaked –
in the Port Settings dialog.
3.5.7.3 Establishing the RF and IF connections
Refer to Chapter 3.5.6.2, "RF and LO cabling", on page 96.
3.5.7.4 Scalar power calibration and leveling (optional)
For standard S parameter measurements which do not require precise power levels at
the DUT, a power calibration is not required.
