Operating Instructions—455/A2/B2
MAGNIFIED SWEEP TRIGGERED AFTER DELAY. At
high apparent magnification, the magnified-sweep-starts-
after-delay method may produce too much jitter. To elimi
nate the jitter, operate B sweep (in the triggered after delay
mode) as follows:
1. Perform steps 1 through 3 of the magnified-sweep-starts-
after-delay procedure.
2. Set the B SOURCE switch to the same position as the
A SOURCE switch. Adjust the B LEVEL control for a
stable intensified zone.
NOTE
Inability to intensify the desired portion o f
the A sweep display indicates the lack o f a
transition o f sufficient amplitude, in that
portion, on which to trigger. If this is the
case, try reducing the VOLTS/DIVswitch
setting for more display amplitude or using
external triggering.
3. Set the HORIZ DISPLAY switch to B DLY'D. To
obtain a stable display it may be necessary to slightly
readjust the B LEVEL control.
