Section 1-7A24 (SN 8103000 & UP)
OPERATING INSTRUCTIONS
The 7A24 Vertical Amplifier unit operates with any Tektroni)( 7000-series oscilloscope mainframe and any 78-
series time-base unit to fo rm a complete oscilloscope system. This section of the manual describes the operation
of the front -panel controls and connectors, provides a functional check procedure, detailed operating information,
and basic applications for this instr ument.
INSTALLATION
The 7A24 is calibrated and ready for use as recei ved.
It can be installed in any compartment of Tektroni)(
7000-series oscilloscopes, but is principally used in
vertical plug -in compartments. To install, align the
upper and lower rails of the 7A24 with the
oscilloscope tracks and fully insert it. The 7A24 is
fully inserted when the front is flush with the front of
the osc illoscope and the latch at the bottom-left corner
of the 7A24 is in place against the front panel. See
Figure 1- 2 for the latch location .
To remove the 7A24, pull on the latch (which is
inscribed with the unit identification " 7A24" ) and the
7A24 will unlatch. Continue pulling on the la tch to
slide the 7A24 out of the OSCilloscope.

Figure 1-3 provides a bri ef description of al l front-
@
panel controls and connectors. See Detailed Operating
Instructions for more information.
FUNCTIONAL CHECK
The followi ng procedures are provided for checking
basic instrument functions. Refer to the description of
the controls and connectors whife performing this
procedure . If performing the functional check
procedure reveals a ma lfunction or possible incorrect
adjustment, first check the operation of the associated
oscilloscope and plug-in units, then refer 10 the
i nstruction manual for maintenance and adjustment
procedures.
