The descriptions above are the basic operating procedures for CH1 single-channel operation of
oscilloscope. So is CH2 single-channel operation. For further operation methods will be explained in the
subsequent paragraph.
Dual-channel Operation
Set the VERT MODE switch to DUAL to display trace in CH2 (The procedure is same as CH1 described
in previous section). At this step, the calibrator signal appears in CH1 is Square wave, but it appears in
CH2 is a straight line as no signal applied to this channel yet.
Now, apply the calibrator signal to the vertical input terminal of CH2 through the probe with the same
procedure as for CH1. Set the AC-GND-DC switch to AC, and adjust vertical POSITION knobs (11) and
(19), the signals will be displayed on both channels as shown in the fi gure.
Signal of CH1
Signal of CH2
When ALT/CHOP switch is released (ALT MODE), the input signals which applied respectively to CH1
and CH2 appears on the screen alternately at each sweep. This setting is used when the sweep time is
short in 2-channel observation.
When ALT/CHOP switch is pressed (CHOP MODE), the input signals which were applied to CH1 and
CH2 are chopped and display on the screen at the same time with the frequency of 250kHz. This setting
is used for low speed sweep.
Set to dual channel operation (DUAL or ADD mode), select CH1 or CH2 signal from SOURCE switch to
get triggering source signal. If both CH1 and CH2 signals are in a synchronized relation, both waveforms
will be displayed in stationary states. If not, only a signal stationary waveform will be appeared. If press
TRIG. ALT push button, both waveforms can also be displayed in stationary states.
ADD Operation
An algebraic sum of the CH1 and CH2 signals can be displayed on the screen by setting the VERT MODE
switch to ADD. The displayed signal will be difference between CH1 and CH2 if press CH2 INV push
button. By adjusting the XXX POSITION knob of CH1 and CH2, the signal can be changed to vertical
position. To make use of the linearity of the vertical amplifi ers, set the XXX POSITION knob of both
channels to the middle position.
