Risk of electric shock
The fuse is part of the main power supply. Therefore, handling the fuse while power is
on can lead to electric shock. Before opening the fuse holder, make sure that the
instrument is switched off and disconnected from all power supplies.
Always use fuses supplied by Rohde
&
Schwarz as spare parts, or fuses of the same
type and rating.
To replace the mains fuse (R&S
ZNBT only)
1. Unscrew the fuse holder from the rear panel and pull the fuse holder out of the slot.
2. Pull the fuse out of the fuse holder and replace it by a new one.
3. Stick the fuse holder back into the slot in the rear panel and screw it tight.
To replace the DC input fuses
► Open the fuse holder by slightly turning the lid counterclockwise.
10.4 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 5.15.1, "Recall Sets Tab"
on page 551. If necessary, move the recall set (
*.znx
file) to the appropriate loca-
tion.
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
.
5. Modify the value
ShowroomSetup
: set its value data to the full path of the recall
set. Use forward slashes as path separators, e.g. "C:/Documents and Settings/All
Users/Rohde-Schwarz/Vna/RecallSets/ShowroomSet1.znx".
After the analyzer is restarted or "Preset", the specfied recall set is loaded.
