Operating Instructions— 2236 Service
Fig. 2-5. Horizontal controls.
1-2-5 sequence. To obtain calibrated sweep speeds,
the A and B SEC/DIV Variable control must be in the
calibrated detent (fully clockwise).
A SEC/DIV
—The calibrated sweep speed is
shown between the two black lines on the clear
plastic skirt. This switch also selects the delay time
for delayed-sweep operation when used in con
junction with the B DELAY TIME POSITION
control.
B SEC/DIV
—The B Sweep speed is set by pulling
out the DLY'D SWEEP knob and rotating it clock
wise to a setting opposite the white line scribed on
the knob. The B Sweep circuit is used only for de
layed-sweep operation.
A and B SEC/DIV Variable Control
— Provides con
tinuously variable, uncalibrated A Sweep speeds to at
least 2.5 times the calibrated setting. It extends the
slowest sweep speed to at least 1.25 s per division.
(
20
) X10 Magnifier Switch
—To increase displayed sweep
speed by a factor of 10, pull out the A and B SEC/DIV
Variable knob. The fastest sweep speed can be ex
tended to 5 ns per division. Push in the A and B
SEC/DIV Variable knob to regain the XI sweep
speed.
( 2 n HORIZONTAL MODE Switch
— Three-position switch
determines the mode of operation for the horizontal
deflection system, and for frequency, period, width,
and totalize measurements.
A
— Horizontal deflection is provided by the A
Sweep generator at a sweep speed determined by
the A SEC/DIV switch setting. Nongated fre
quency, period, width, and totalize measurements
are made on the A Trigger signal.
ALT
— Alternates the horizontal displays between
the A Sweep (with an intensified zone) and the B
Delayed Sweep. The A Sweep speed is determined
by the setting of the A SEC/DIV switch. The B
Sweep speed and the length of the intensified zone
on the A Sweep are both determined by the B
SEC/DIV switch setting. Gated frequency, period,
width, and totalize measurements are made on the
B Trigger signal. The gate interval is defined by the
length of the intensified zone and is valid only when
B Sweep is triggered.
B
— Horizontal deflection is provided by the B
Sweep generator at a sweep speed determined by
