The output voltages of the RFFE and GPIO signals do not have an offset to compen-
sate additional losses into account. Please adjust the voltage level directly on your
board or at the pins of the connected device.

12.4 Showroom mode
In "Showroom Mode" the R&S ZNB/ZNBT uses a configurable recall set whenever the
device is (re-)started or the [Preset] key is pressed. However, it can only be enabled by
directly editing the Windows registry.
1. Run the R&S ZNB/ZNBT and configure it as required for the intended showroom
operation.
2. Save the configuration as described in Chapter 5.14.1, "Recall sets tab",
on page 669. If necessary, move the recall set file (*.znx|*.znxml) to the appro-
priate location.
3. Under the registry key
HKEY_LOCAL_MACHINE/SOFTWARE/Rohde-Schwarz/Vna, create a new subkey
ShowroomMode.
4. Within the ShowroomMode-subkey, create the string value ShowroomSetup.
