deflection factor between steps of the VOLTS
/DIV switches. VOLTS/DIV calibrations are
accurate only when the VARIABLE controls are
click-stopped in their fully clockwise position.
(15) (16) VARIABLE control To increase the vertical amplifier sensitivity
(on VARIABLE) by 5 times. The effective scale factor of the
most sensitive position of the VOLTS/DIV switch
thereby becomes 1mV/div.
(17) CH1 POSITION control For vertically positioning the CH1 trace on
the CRT screen, Clockwise rotation moves the
trace up, counterclockwise rotation moves the
trace down.
(18) CH2 POSITION For vertically positioning the CH2 trace on the CRT
screen. Clockwise rotation moves the trace up,
counterclockwise rotation moves the trace downward.
(18) PULL CH2 INV switch When pulled, the polarity of the CH2 signal
(on CH2 POSITION control) is inverted.
(19) V MODE switch When pulled, the polarity of the CH2 signal
is inverted.
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 CH1 and
CH2 input signal on the CRT screen
simultaneously.
CHOP mode : TIME/DIV 0.1s~5ms
ALT mode : TIME/DIV 2ms~0.1
㎲
ADD position displays the algebraic sum of CH1
&CH2 signals.
(20) CH1 OUTPUT connector Provides amplified output of the channel 1
signal suitable for driving a frequency
counter or other instrument.
