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
and conditions"
●
"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.
General communication error
In this case, check whether the device is properly connected to the configured
interface.
Self test error
In this case enable error logging for external devices (see
on page 780), and search the
device.
– The device driver does not match exactly the device type. Probably the device
