Operators
BASIC APPLICATIONS
INTRODUCTION
The procedures
in
this section enable the operator to make basic measurements using the capabilities
of
the oscillo-
scope. Many of these measurements can
be
obtained with either the nonstorage mode or one
of
the storage modes. After
becoming familiar with the capabilities
of
the instrument, the operator can choose the best method for making a particular
measurement.
Read
the "Operating Considerations" part
of
this manual for information
on
signal connections, grounding,
and other general operating information that may
be
useful
in
your application.
When the procedures call for obtaining a baseline display, refer to Initial Setup
in
the "Operator's Checks and Adjust-
ments" part
of
this manual. The initial control settings listed
in
the Initial Setup procedure
are
considered
as
the initial con-
trol setup. Alternate control settings are usually required for making a specific measurement. The operator must determine
the correct control settings applicable to VOL TS/DIV, SEC/DIV, TRIGGER,
and
other controls to obtain a stable display
of
the desired display. Only the readouts necessary for each specific example
are
shown
in
their associated illustrations.
OSCILLOSCOPE DISPLA VS
The following procedures will allow the operator to set up
and
operate the instrument to obtain the most commonly used
oscilloscope displays. Verify that the POWER switch
is
OFF
(push button out), then plug the power cord into the ac-power-
input source outlet.
NON STORE DISPLA VS
The following procedures are used to obtain the most
commonly used conventional oscilloscope displays.
Normal Sweep Display
1 . Preset the instrument controls
and
obtain a baseline
display.
2.
Using the supplied 1
OX
probe or a properly ter-
minated coaxial cable, apply a signal to the
CH
1
OR
X
input connector. The signal source output impedance
determines the termination required when using a coaxial
cable to interconnect test equipment.
NOTE
Instrument warm up time required to meet all
specification accuracies is
20
minutes.
3.
Advance the A INTENSITY control until the display
is visible. If the display
is
not visible with the INTENSITY
control at midrange, press the BEAM
FIND
push button
and
hold it
in
while adjusting the Channel 1 VOL TS/DIV
switch to reduce the vertical display size. Center the
compressed display using the Vertical
and
Horizontal
POSITION controls. Release the BEAM
FIND
push button.
4.
Set the Channel 1 VOL TS/DIV switch
and
the Verti-
cal
and
Horizontal POSITION controls to locate the display
within the graticule area.
5.
Adjust the A TRIGGER LEVEL control for a stable,
triggered display.
6.
Set the A SEC/DIV switch for the desired number of
cycles of displayed signal. Then adjust the FOCUS control
for the best defined display.
