Section 2 - 7934 Operator's
OPERATING INSTRUCTIONS
To operate the 7934 effectively, the user must become
familiar with its operation and capabilities. This section de-
scribes how to use the front- and rear-panel controls and
connectors.
For detailed operating information on specific plug-in
units used with the 7934, refer to the manualfor that unit.
To avoid electric-shock hazard, see installation in the
GeneralInformation section of this manual before op-
erating this instrument.
PLUG-IN UNITS
The 7934 accepts up to four Tektronix 7000-Series plug-
in units. This feature allows selection of bandwidth, sensitiv-
ity, display mode, etc., and provides for future expansion of
the system.
The overall capabilities of the system are mainly deter-
mined by the characteristics of the selected plug-ins. Some
typical combinations are given under Applications in this
section. For information on other plug-in units, refer to the
current Tektronix Products Catalog.
installation of Plug-in Units
To prevent instrument damage, plug-in units should
not be installed or removed withoutfirst turning the
instrument power off.
To install a plug-in unit into a compartment, align the
slots in the top and bottom ofthe plug-in unit with the asso-
ciated guide rails in the plug-in compartment. Insert the
plug-in unit into the compartmentuntil it locks into place. To
remove a plug-in unit, pull outward on the release latch to
disengage the plug-in. To meet the EMC (electromagnetic
compatibility) specifications, cover all unused plug-in
compartments with an EMC shielded blank plug-in panel,
Tektronix Part 016-0155-00.
The gain of the 7934 vertical and horizontal systems has
been normalized to allow plug-in units to be interchanged
among plug-in compartments without readjustment of the
system. The basic calibration of the plug-in units should be
checked wheninstalled to verify their accuracy {refer to the
operating instructions in the plug-in manual).
CONTROLS AND CONNECTORS
The 7934 front and rear panels are shown in Figure 2-1
and Figure 2-2. A brief, functional description of each control
and connectoris included in theseillustrations. Refer to De-
tailed Operating information for additional information.
Froni-Panel Color Coding
The 7934 front panel is color coded to define areas by
function. Blue identifies controls that affect the display
mode; green identifies triggering controls.
Other colors such as gray, orange, and yellow have no
functional assignment, but indicate a relationship among
controls and/or connectors.
