Operating lnstructlons-5110
A thermal cutout in the display module provides
thermal protection and disconnects the power to the
instrument if the internal temperature exceeds a safe
operating level. This device will automatically re-apply
power when the temperature returns to a safe level.
PLUG-IN
UNITS
The oscilloscope is designed to accept up to three
Tektronix 5000-series plug-in units (use only "N" suffix
plug-in units unless otherwise specified). This plug-in
feature allows a variety of display combinations and also
allows selection of bandwidth, sensitivity, display mode,
etc., to meet the measurement requirements. In addition, it
allows the oscilloscope system to be expanded to meet
future measurement requirements. The overall
capabilities of the resultant system are in large part
determined by the characteristics oftheplug-insselected.
Installation
To install a plug-in unit into one or the plug-in
compartments, align the slots in the top and bottom of the
plug-in with the associated guides in the plug-in compart­
ment. Push the plug-in unit firmly into the plug-in
compartment until it locks into place. To remove a plug-in,
pull the release latch on the plug-in unit to disengage it
and puli the unit out of the plug-in compartment. Plug-in
units should not be removed or installed without turning
off the instrument power. It is not necessary that all of the
plug-in compartments be filled to operate the instrument,
the only plug-ins needed are those required for the
measurement to be made.
When the oscilloscope is adjusted in accordance with
the adjustment procedure given in this manual, the vertical
and horizontal gain are standardized. This allows adjusted
plug-in units to be changed from one plug-in compart­
ment to another without readjustment. However, the basic
adjustment of the individual plug-in units should be
checked when they are installed in this system to verify
their measurement accuracy. See the plug-in unit manual
for verification procedure.
Selection
The plug-in versatility of the oscilloscope allows a
variety of display modes with many
different plug-ins. The
following information is provided here to aid in plug-in
selection.
NOTE
Use only "N" suffix plug-in units with the os­
cilloscope unless otherwise specified.
To produce a single-trace display, install a single­
channel vertical unit (or dual-channel unit set for single­
channel operation) in either of the vertical (left or center)
compartments and a time-base unit in the horizontal
(right) compartment. For dual-trace displays, eitherinstall
a dual-channel vertical unit in one of the vertical com­
partments or install a single-channel vertical unit in each
vertical compartment. A combination of a single-channel
and a dual-channel vertical unit allows a three-trace
display; likewise, a combination of two dual-channel
vertical units allows a four-trace display.
To obtain a vertical sweep with the input signal
displayed
horizontally, insert the time-base unit into one
of the vertical compartments and the amplifier unit in the
horizontal compartment. If a vertical sweep is used, there
is no retrace blanking; however, if used in the right vertical
(center)
compartment, internal triggering is provided.
For X-Y displays, either a 5A-series amplifier unit ora
5B-series time-base unit having an amplifier channel can
be installed in the horizontal compartment to accept the X
signal. The Y signal is connected to a 5A-series amplifier
unit installed in a vertical compartment.
Special purpose plug-in units may have specific restric­
tions regarding the compartments in which they can be
installed. This information will be given in the instruction
manuals for these plug-ins.
CONTROLS AND
CONNECTORS
Controls and connectors necessary for operation of the
oscilloscope are located on the front and rear panels of the
instrument. To make full use of the capabilities of this
instrument, the operator should be familiar with the
function and use of each external control and connector.
A brief description of the controls and connectors is given
here.
More detailed information is given under General
Operating Information (later in this section). See Fig. 1-2
for the location and description of the controls and
connectors.
FIRST TIME OPERATION
The following procedure provides an operational
checkout as a means of verifying instrument operation
and basic calibration without removing the cabinet or
making internal adjustments. Since it demonstrates the
use of front-panel controls and connectors, it can also be
used to provide basic training on the operation of this
instrument. If recalibration of the oscilloscope or plug-ins
appears
to be necessary, refer the instrument system to
qualified service personnel. If more familiarization with a
plug-in unit is needed, see the instruction manual for the
appropriate plug-in unit. Refer to Fig. 1-2 for the os­
cilloscope control and connector locations.
