SAFETY
SUMMARY
TERMS
WARNINGS
This
product is intended to operate in a mainframe connected to a power source that will not apply more than 250 volts
rms between the supply conductors or between either supply conductor and ground . A protective ground connection by
way of the grounding conductor in the mainframe power cord is essential for safe operation .
This product is grounded through the grounding conductor of the mainframe power cord . To avoid electrical shock, plug
the mainframe power cord into a properly wired receptacle before connecting to the product input or output terminals . A
protective ground connection by way of the grounding conductor in the mainframe power cord is essential
for safe
operation
Upon loss ; of the protective-ground connection, all accessible conductive parts (including knobs and controls that may
appear tc be insulating), can render an electric shock .

Volume
51310 FEATURES
I
3697-145
The 51310 Waveform Digitizer is designed to enhance the capabilities
of 5000-series oscilloscope mainframes .
Waveform storage, crt
readout,
two cursors for point-to-point measurements, pretrigger viewing, user
adjustable viewtime,
X-Y
display,
and analog plot output are
just a few of the features this double-wide plug-in unit provides .
Waveform s orage using digital memory eliminates
the need for a storage crt and allows viewing information which occurred prior to a
triggering event . Acquisition
may be halted by a triggering
event and automatically restarted at the end of the user-adjustable
viewtime .
A complete numerical display, of cursor measurement values, and time base and amplitude settings is generated by the 51310 (a readout-
equipped m 3inframe is not required) .
The front p< nel XY plot output properly connected to an XY recorder provides a hard copy of all information on the crt .
The 51310 is capable of
displaying and storing three channels
simultaneously when used with a dual channel vertical amplifier such as the
5A1 8N .

INITIAL
INSPECTION
This instalment
was inspected both mechanically and
electrically
before shipment . It should be free of mars or
scratches and should meet or
exceed all electrical
specifications . To confirm this, inspect
the instrument for
physical damage
incurred in transit and check the basic
instrumenl
functions by following the Detailed Checkout
Procedure
in Section 2, Operating Instructions .
Performarn .- e Requirements can be
verified by referring to
the Calibration section of
this manual . If there is damage
or deficiency,
contact your local Tektronix Field Office or
representative .
OPERATING
TEMPERATURE
The 51310 can be operated where the ambient
air
temperature is between 0°
and
+45°
Cand can be stored
in ambient temperatures
from
-55° to +75° C .
After
storage at temperatures
outside the operating limits,
allow the
i ;hassis temperature to reach operating limits
before applying power .
MAINFRAME COMPATIBILITY
The 51310
operates in the right vertical and horizontal
compartments
of any 5000-series mainframe, however
some
mainframes may require modification . Refer to
Table 1-1 for 5100-series mainframes that
require
modification to the Interface board before the
Left Plug-in
mode may be used
for channel 2 signal acquisition .
WARNING
Only
qualified service personnel are
authorized to
make modifications .
We
recommend that all
mainframes requiring
modificai ion
number
M45180
also incorporate
modification number
M44151 to prevent changes
in
display vertical
position and gain when the left
plug-in is
installed cr
removed . Modifications
are described in the
Maintenance section of this
manual .
If the 51310 is used in the 5111,
5111A,
5113,5115,
or
the 5441 Storage
Oscilloscope, the mainframe should be
operated only
in the non-storage mode .
If the
51310 is used in the 5115 Storage Oscilloscope,
the
Enhance control must be
rotated fully counterclockwise .
When the
51310 is installed in the 5223 Digitizing
Oscilloscope,
the mainframe is used only for real-time
displays . The 5223 digitizing functions are
inoperative .
We do not
recommend use of the LEFTPLUG-IN function
when the 51310 is installed in the 5223,5440,5441,
or
the 5444 Oscilloscope
mainframe .
INSTALLING
THE 51310 IN THE MAINFRAME
The 51310 is designed to
operate in the right vertical and
horizontal plug-in compartments
.
NOTE
Switch off the
mainframe power before
installing or
removing the 51310 .
To
install the 51310 in the mainframe,
align the grooves
in the top and bottom of the
instrument with the guides
at the top and bottom of the plug-in
compartment . Then
push the
51310 in until its front panel is flush with the
front
panel of the mainframe . See Figure 1-1 .
NOTE
Make sure that both halvesof
the 51310 are
firmly seated
against the mainframe front
panel .
To
remove the unit, pull both
release latches
simultaneously to
disengage the unit from the
mainframe, then pull
it from the plug-in compartments
leaving
the mainframe on the bench .

PLUG-IN
COMPATIBILITY
Any
5000-series
amplifier plug-in may
be used in the left
vertical
compartment
of the
oscilloscope mainframe as a
single-trace
signal source
for 51310 channel 2
however,
we recommend
the
incorporation of a noise
reduction
modification
to some
differential
amplifier units . The
modification
number and affected
plug-in units are listed
in Table 1-2 .
For dual-trace
acquisition,
compatibility
considerations
listed in
Table 1-3 must
be observed .
