7623/R7623
Service
shortened
accordingly.
For example, the basic measurement
capabilities of this
instrument can be verified by
checking
vertical
deflection
accuracy, vertical square-wave
response,
and basic horizontal
timing with
7000-series real-time
plug-in
units and an accurate square-wave signal. Also, if the
7623 is to
be used in a
fixed system without the need to
interchange
plug-in units, all tests can be
made by substi
tuting
vertical plug-in units and applicable test signals for
the
067-0587-01 mainframe standardizer
calibration fix
ture.
