the
next positive-going
Sweep Hold-off pulse. The action is
the same
with
each pulse, so the signal at the output of this
stage is at
the
same repetition rate as the Sweep Holdoff
input.
Therefore, this stage is now operating as a divide-by-
one
counter rather than a divide-by-two counter as
described
previously.
The output under this condition is
used
only
by the Plug-In
Binary stage.
Since
the Vertical Binary stage can change output states
only
at
the end of each sweep, there will be no Alternate
Drive signal
for either the mainframe or vertical
plug-in
units
if a sweep is not being produced by the horizontal
plug-in
unit.
Plug-In
Binary
The
Plug-In Binary stage
consists of U156B, which is
connected
as a triggered flip-flop with direct-set input. The
trigger
input for this stage is the
Display Right Command
from
the Vertical Binary stage. When
the VERT MODE
switch
is
set to ALT, the repetition
rate of the Display
Channel
2 Command output of this stage is one-fourth of
the Sweep
Holdoff
input (see waveforms in Fig. 3-11). For
any
position
of
the VERT MODE switch
except ALT, the
repetition
rate of the
output signal from this stage
is
one-half of the Sweep Holdoff
input. A logic diagram of the
Plug-In
Binary stage is shown in Fig. 3-12.
