12.4 Showroom mode
In "Showroom Mode" the R&S ZNA 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 ZNA and configure it as required for the intended showroom opera-
tion.
2. Save the configuration as described in Chapter 5.15.1, "Recall sets tab",
on page 772. If necessary, move the recall set file (*.znxml|*.znx) to the appro-
priate location.
3. Under the registry key
HKEY_LOCAL_MACHINE/SOFTWARE/Rohde-Schwarz/ZNA, create a new subkey
ShowroomMode.
4. Within the ShowroomMode-subkey, create the string value ShowroomSetup.
