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 707. 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
.
