The following procedures will enable the operator to perform some basic measurements and familiarize the operator with
digital storage measurement techniques .

switch
setting that
gives
the
desired
vertical deflection

4. Set the
SEC / DIV
switch
to
display
several cycles of
the
waveform .
8. Read the peak - to - peak amplitude from the DELTA
VOLTS readout . If the VOLTS / DIV Variable control is out
of the calibrated detent , the DELTA VOLTS readout
switches to RATIO .
5. Two cursors are displayed on the waveform to be
measured .
The
boxed
cursor is
the
active
(
selected )
cursor
.

6. Use
the
CURSORS
control
to
move the
active
cur
sor to either peak of the waveform .
NOTE
Either channel input connector may be used for the
signal input . Use the VERTICAL MODE switches to
select
the
appropriate
channel for
display .
7. Push
the
SELECT C1 / C2
button
to
select
the
other
cursor , and
use the
CURSORS control
to move the
cursor
to the
opposite peak of the
waveform
( see
Figure 6-12 ) .

2.
Determine the
polarity
of
the

After the
waveform is
acquired , the
SAVE
Storage
mode may be selected .
This mode
holds the
waveform
frozen
and reduces
the
amount of
cursor
jitter
seen in the
display
.
The
SAVE
display may be
expanded horizontally and vertically for a more
detailed
examination
of
the
waveform ( see
SAVE

AC - GND
- DC
switch to GND
and
verti
cally position the baseline trace to the center
