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).
b) In the combo box above the "Splitter 1" symbol, select "Conv. LO" as LO
source.
c) For both converter ports, select "Splitter 1" as the source for the "Local"
port.

3. Select "OK" to apply the converter configuration and close the dialog.
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 (see
the R&S
ZNA user manual or instrument help). 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.
(System – [Setup] key > "Frequency Converter" tab > "Save Converter Top-
ology"/"Load Converter Topology").
