5-5.Basic Operation
Displaying CH1 or CH2
To display the signal from a signal channel, pressing briefly the CH1 or
CH2 pushbutton to set the oscilloscope to channel 1 or channel 2.
Displaying CH1 and CH2
To display both signals at the same time, proceed the following steps:
1.Set the CH1 and CH2 on. The figure 5-5 below shows two synchronous
waveforms in the both modes.
2.Adjust the CH1 or CH2 POSITION control to position the two
waveforms.
3.Set the ALT/CHOP/ADD button to CHOP mode if the waveforms are
flickering.

Displaying the sum or difference of CH1 and CH2
To display the algebraic sum or difference of CH1 and CH2, proceed the
following steps:
1.Set the ALT/CHOP/ADD button to ADD mode. The figure 5-6 below
shows the sum of the waveforms from figure 5-5.
2.Set the CH2 INV on by pressing and holding the button, if necessary,
to display the different waveform.
3. Pressing and holding one of the VAR buttons to set the VOLT/DIV
control knob to vernier (variable). Then adjust one channel to the other
in the event of gain difference.
