the
X10
MAG switch. The
sweep
rate
of
the delayed
sweep
(B
Sweep)
is
not
actually increased. The apparent magni-
fication
is
the result
of
delaying the B
Sweep
an
amount
of
time determined
by
both the A
TIME/DIV
switch
and
the
DELAY
TIME POSITION control before the display
is
presented at the
sweep
rate selected by the B
TIME/DIV
switch. The following method
uses
the STARTS
AFTER
DELAY
position
of
the B
(DLY'D)
TRIGGER SOURCE
switch
to
allow the delayed portion
to
be
positioned
with
the
DELAY
TIME POSITION control.
If
too
much
jitter
occurs in the delayed display,
use
the Triggered Delay
Sweep
Magnification procedure, which follows the Magni-
fied
Sweep
Starts
After
Delay procedure.
Magnified Sweep Starts After Delay
1.
Obtain a Normal
Sweep
Display (refer
to
Basic
Oscilloscope Displays section
of
this manual).
2.
Set
the appropriate
VOL
TS/DIV
switch
to
produce a
display about
two
divisions in amplitude.
3. Set the A
TIME/DIV
switch
to
a
sweep
rate which
displays
several
waveform cycles.
4.
Depress
the
HORIZ
DISPLAY
ALT
push button and
set
the B
(DLY'D)
TRIGGER SOURCE switch
to
STARTS AFTER
DELAY.
If
the instrument
is
equipped
with
a DM44, verify
that
neither the
TIME
nor
1/TIME
FUNCTION switch
is
set.
5.
Adjust channel POSITION control and TRACE
SEP
to
display A
and
B
Sweeps,
one
above the other.
6. Position the start
of
the intensified
zone
with
the
DELAY
TIME
POSITION control
to
the part
of
the
display
to
be
magnified.
7.
Set
the B
TIME/DIV
switch
to
a setting which
intensifies the
full
portion
to
be
magnified and
displays
that
portion
as
the B
Sweep
(see
Figure 24).
The B
INTENSITY
control may require adjustment
to
display the B
Sweep
(magnified
portion).
