Tektronix 7834 User Manual

Refer to Table 1-4 in the General Information section for
specifications on Z-axis signal requirements .
Time markers applied to the Z-AXIS INPUT provide a
direct time reference on the display . With
uncalibrated
horizontal sweep or X-Y mode operation, the
time markers
provide a means of reading time directly
from the display .
If the markers are not time-related to the displayed wave-
form, use a single-sweep display .
Remote Input Signals
The signal source requirements to operate the remote input
functions
on the rear panel can be either active (pulse
generator, logic
circuit, etc .) or passive (switch or relay) .
Refer to Table 1-4, in the General
Information section for
specific parameters on each input .
REMOTE
RESET INPUT . An external single-sweep-reset
signal can be
applied to time-base units installed in the
horizontal plug-in
compartments through the rear-panel
REMOTE RESET
INPUT connector . This remote reset
function is a duplication
of the manually-operated single
sweep reset function (push
button) located on the front
panel of the 7B-Series time-base
units .
REMOTE ERASE INPUT . The
storage screen can be
erased by applying a signal
to the REMOTE ERASE INPUT .
However, if the SAVE
mode is being used the stored
display cannot be erased by
either front-panel erase con-
trols or the rear-panel REMOTE
ERASE INPUT signal .
REMOTE SAVE INPUT . The
SAVE storage mode can be
entered into by applying
a signal to the REMOTE SAVE
INPUT connector . The
SAVE mode prevents accidental
erasure and/or additional
storage of the stored display .
REMOTE STORAGE GATE INPUT . The
FAST BI-
STABLE and FAST VAR PERSIST storage
modes can be
externally controlled by applying a gate signal
to the
REMOTE
STORAGE GATE INPUT . The positive-going
transition of the gate
enables the transfer storage mesh to
retain the display . The
negative-going transition transfers
the display stored on the
transfer storage mesh to the
storage screen (the display is not visible
until transferred to
the
storage screen) . However, if the displayed
sweep starts
before
the positive transition of the remote storage
gate
the transfer
storage mesh is enabled at the start
of the
displayed sweep .
Then, the display stored on the transfer
storage mesh
will not be transferred until the displayed
sweep
has ended and the negative transition of the remote
storage
gate occurs .
APPLICATIONS
Operating Instructions-7834
The
7834 Oscilloscope and its associated plug-in units
provide a flexible
measurement system . The capabilities of
the overall
system depend mainly upon the plug-in units
selected for use with this instrument . Specific applications
for the individual plug-in units are described in the plug-in
unit instruction manuals . The overall system can also be
used for many applications which are not described in
detail, either in this manual or in the manuals for the
individual plug-in units . Contact your Tektronix Field
Office or representative for assistance in making specific
measurements with this instrument .
The following
books describe oscilloscope measurement
techniques which can be
adapted for use with this
instrument :

and
Application", Prentice-Hall Inc ., Englewood
Cliffs, New Jersey, 1968 .

Vertical Amplifier
Plug-In Units
All 7A-Series plug-in units (except
the 7A21N unit) can be
used with the
7834
.
Bandwidth and sensitivity ranges
should be taken
into consideration when selecting amplifier
plug-in
units .
SINGLE-TRACE . Any
single-channel amplifier will display
a signal, with the sweep provided
by any 7B-Series time-
base plug-in . This combination
leaves two unused com-
partments available for other
special purpose units . Blank
plug-in panels are available to cover any unfilled
plug-in
compartments .
DUAL-TRACE
. A dual-channel amplifier in either vertical
compartment can
display two separate signals with the
other vertical
compartment free for other uses .
THREE-TRACE . A dual-channel amplifier can
be used
with any single-channel amplifier
to display three separate
signals
. If two time-base plug-in units are
used in the
horizontal compartments, two signals can be
displayed at
one sweep rate while the other signal is displayed
at the
other sweep rate .
