at
a rate
deter-
mined
by
the
A
TIME/DIV switch. An intensified
portion
can appear on the
display
during the B
Sweep time. This switch position provides an
indication of both the duration and position of the
B
Sweep
(delayed
sweep)
witn
respect to tne
a
S
weep (delaying sweep)
ALT—
Alternates
the displays between the A
INTEN and B DLY'D Sweeps. In ALT operation,
use
TRACE SEP
to
vertically position
B
Trace;
use B INTENSITY
control
to adjust B Trace
intensity.
B DLY'D—Displays
only the B Sweep The B
Sweep rate is determined
by
the
B
TIME/DIV
switch, with
the
delay
time determined by the
setting
of both the A

EXT Z-AXIS—Input bnc connector permits the
application of an external signal to intensity
modulate the crt display Does not affect display
wave-shape Signals with fast rise time and fall time
provide the most abrupt intensity change. Signals
must
be
time-related to the display for a stable
presentation on the crt The connector is useful for
adding time markers in uncalibrated modes of
operation.
