+The 7934 is a 500MHz [[CRT storage scope]] multi-mode storage mainframe with four bays for [[7000-series plug-ins]] — two vertical (left) and two horizontal (right).
-Performance and function is largely determined by the installed 7000-series plug-ins.
-Plug-ins have a wide variety of functions, including: current and voltage amplifiers,
-time-bases, spectrum analyzers, sampling amplifiers and time-bases, logic analyzers, as well as a variety of miscellaneous plug-ins.
-The plug-in modules each use 1, 2 or 3 bays.  Storage is provided by variable persistence and bi-stable modes.
 Amplifiers are normally installed in the two vertical bays to provide vertical beam deflection,

 Many orthogonal modes of operation are available on the 7934, which control the vertical mode,
 horizontal mode, storage mode, and triggering:
-Storage has normal, bi-stable (standard and "fast"), variable-persistence (standard and "fast") modes,
-as well as independently-switchable reduced-scan mode (to aid high-speed writing) and timed auto-erase.
 The mainframe has the usual analog ch1/ch2/alt/chop/add vertical-mode functions for the two vertical bays,

 The horizontal modes (A/B/alt/chop) allow the horizontal deflection to be controlled by either the A or B compartment only,
 or by both, on a time-sharing basis.  The mainframe also provides hold-off signals between the two horizontal,

 as well as either compartment's internal trigger signal.  Only one connector is available for each function,
 and the compartment is selected by jumpers on a circuit board near the rear of the case.
