HORIZ DISPLAY Selects
the mode of
operation for
the horizontal
deflection system.
A: Horizontal deflection
is provided by
the A sweep
generator
at a
rate
set
by A
TIME/DIV.
The B
sweep
generator (delayed sweep) is
dis-
abled.
MIXED: The first
part of the
sweep is displayed
at a
rate set by A
TIME/DIV
and the last
part of the
sweep is displayed at a
rate set
by
B
TIME/DIV. The relative
amount of display
controlled
by
each set-
ting is
determined
by
the
setting on the
DELAY TIME POS dial.
A
INTEN: Horizontal
deflection is
provided
by
the
A
sweep generator
at a
rate set
by
A
TIME/DIV. The B
sweep generator produces
an in-
tensified
zone on the display. The
length of time the display is
intens-
ified is about ten times the B
TIME/DIV setting except
when A sweep
ends before B sweep.
The location of the
intensified zone on the dis-
play is
determined
by
the
DELAY TIME POS dial setting.
B
DLY'D: Horizontal
deflection is provided by
the
B
sweep generator
at a
rate set by B
TIME/DIV. The A sweep generator
continues
to
operate. With the
B
sweep SOURCE
set
to
STARTS
AFTER DE-
LAY,
the start
of
B
sweep
is
delayed
from the start of A sweep
by
a
time determined
by the
settings
of A
TIME/DIV and
DELAY TIME
POS. To
calculate
the delay,
multiply the A
TIME/DIV setting
by
the
DELAY TIME POS dial setting.

POSITION Provides horizontal positioning control
of the display, except in
the
X-Y
mode of operation
when the CH 1 OR X,

INTEN or B
DLY'D
display
modes.
For calibrated
