If the R&S
ZNA fails to detect a connected generator,
► Click "Add Device" to define the interface type and address.
The R&S
ZNA can auto-detect the instrument type (driver) and the serial number of
the connected generator.
To control external devices via GPIB, the pre-installed RS Visa library (
visa32.dll
)
must be replaced by the
NI Visa
library.
Known Devices
Table with all generators that the analyzer detects to be on line (i.e. connected and
switched on). "Scan Instruments" refreshes the table; copies a detected instrument
to the table of "Configured Devices".

Configured Devices
Table with all generators in use with their properties. The properties of manually config-
ured generators ("Add Device", opens the "Add External Generator" dialog) may be
changed in the dialog.
The following generator properties are not defined in the "Add External Generator" dia-
log but configurable here:
●
"Ext. Ref." switches the generator to either external (box checked) or internal fre-
quency reference. The setting does not affect the frequency reference settings of
the analyzer System – [Setup] > "Freq. Ref.". Make sure to establish consistent
settings in your test setup (one instrument is the master, the others use external
reference frequency). See
●
"Fast Sweep" enables or disables the fast sweep mode for external generators that
support a frequency and level list mode (triggered mode). See
●
"Sweep End" defines the output power of the external generator after the end of a
sweep or sweep sequence (single sweep mode; Channel – [Sweep] > "Sweep
Control" > "Single"). The minimum power value ("Switch to Min. Power") depends
on the generator type. "Set to Selected Power" means that the generator is com-
manded to transmit at the selected "End Power".
The following symbols (grayed out for
used
devices) indicate the status of the respec-
tive device:
●
–
The device is online (connected, switched on, ready to be used).
●
–
There is a problem with the device.
This state can be caused by different problems:
–
General communication error
In this case, check whether the device is properly connected to the configured
interface.
