Extended Functions with Diagnostic
Exercisers
Diagnostic exercisers provide access
to
an
operating-time log and they control
instrument setup modes and the viewing-time display. The available
GPIB interface
adds exercisers to establish system parameters
of
the instrument and
to
transfer the
set of thirty saved setups from one instrument to one or more other instruments. With
the available Television/Video
(TV) enhancement, added exercisers control video line
numbering. The available
DMM
also adds
an
exerciser,
DM
EXER 72. The Service
Manual describes other exercisers which are used only for instrument testing and
troubleshooting.
