VOLTS/DIV calibrations are accurate only when the VARIABLE controls are click-stopped in their
fully clockwise position.
(3)
X5 MAG switch
The sensibility of vertical axis will become 5 times if the switch is selected at X5 MAG. That's to
say, the measuring voltage will be 1/5 of indicator value of volts/div. (in this instance the
maximum sensitivity will be 1 mV/div.)
(4)
CH 1 POSITION control
For vertically positioning the CH 1 trace on the CRT screen. Clockwise rotation moves the trace
upward, counterclockwise rotation moves the trace down.
(7)
CH 2 Position control
For vertically positioning the CH 2 trace on the CRT screen. Clockwise rotation moves the trace
upward, counterclockwise rotation moves the trace downward.
(6)
CH 2 INV switch
Select switch at INV the signal added to CH 2 will be turned over.
(5)
V MODE Switch
To select the vertical-amplifier display mode.
CH1 position displays only the channel 1 input signal on the CRT screen.
CH2 position displays only the channel 2 input signal on the CRT screen.
DUAL position displays the CH 1 and CH 2 input signal on the CRT screen simultaneously.
CHOP mode: TIME/DIV 0.2 s-5 ms
ALT mode: TIME/DIV 2 ms-0.2 µs
VERT/ALT mode: TIME/DIV 0,2 s x – 0,2 µs
ADD position displays the algebraic sum of CH 1 & CH 2 signals.

CH 1 OUTPUT connector
Connector provides amplified output of the channel 1 signal suitable for driving a frequency
counter or other instrument.

Sweep and Trigger Blocks

(15)
TIME/DIV switch
To select either the calibrated sweep rate of the main timebase, the delay-time range for delayed-
sweep operation, or X-Y operation
(13)
CAL/VAR switch
to change between CALibrated Time/Div steps and VARiable control
(12)
VARIABLE control
Provides continuously variable adjustment of sweep rate between steps of the TIME/DIV switch.
TIME/DIV calibrations are accurate only when the VARIABLE control is click-stopped fully
clockwise.
(11)
X10 MAG switch
Placing the switch on X10 MAG sweep time will expanded to 10 times and in this instance sweep
time becomes 1/10 of TIME/DIV inicator value.
(10)
Horizontal POSITION control
To adjust the horizontal position of the traces displayed on the CRT. Clockwise rotation moves
the traces to the right, counterclockwise rotation moves the traces to the left.
(14)
Trigger MODE switch
To select the sweep triggering mode. AUTO position selects free-running sweep where a
baseline is displayed in the absence of a signal. This condition automatically reverts to triggered
sweep when a trigger signal of 25 Hz or higher is received and other trigger controls are properly
set.
NORM position produces sweep only when a trigger signal is received and other controls are
properly set. No trace is visible if any trigger requirement is missing. This mode must be used
when the signal frequency is 25 Hz or lower.
