Calibration — 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.
