The Tektronix 7603 is a general-purpose 100 MHz non-storage scope that takes
two 7000-series vertical plug-ins
and one 7000-series horizontal plug-in.
It was made in various versions for many years. Some have a fan, some don't. There are at least two variants of the vertical output amplifier.
The AN/USM 281C is essentially a 7603 with option 01 (no readout = 7603N).
