The External Generators dialog provides two tables and some additional buttons.
 The upper table (Found:) shows all generators that the analyzer detects to be on-line (i.e.
connected and switched on). All generators in the table must have been configured previously,
however, they can be deleted in the lower table.
 The Add v and Add All v buttons copy the selected generator in the upper table to the lower table.
 The lower table (Configured:) shows all configured generators with their properties. The properties
are defined in the Add/Modify External Generator dialog, to be opened by means of the Add
Other... or Modify... buttons. All configured generators are available as additional sources for
measurements and power calibrations.
An icon in the first columns of the tables indicates whether the generators are currently available; see
below. The Found: table and the icons in the Configured: table are automatically updated each time the
External Generators dialog is opened (to update explicitly use the Refresh Tables button). The remaining
control elements are self-explanatory.
Unintentional switchover to remote control
When using the NI-VISA library, ensure that the network analyzer itself is not listed as a network device in
the Measurement & Automation Explorer. Otherwise, Refresh Tables will send an identification query
(*IDN?), causing the analyzer to close the System Configuration dialog (without executing Refresh
Tables) and to activate the remote screen.
Icons in the generator tables
The following icons describe the status of a generator:
The generator is on-line (connected, switched on, ready to be used).
The generator was detected (upper table) or configured (lower table) but is not on-line (VISA
communication error). Other possible reason: a user-defined power meter configuration file is inconsistent;
see General Rules for Configuration Files.
The generator list could not be refreshed, no communication with the generator is possible.
