By using both channels on the instrument you can compare one signal
Channels
directly with another. With one signal in each channel it is also very easy to
algebraically add them together or subtract them from each other.

Comparing
TWO
Signals

Step 1
:
Connect one signal to Channel
1
and the other signal to Chan-
nel
2.
Move the
CHI BOTH CH2
switch to
BOTH.
C]
Step 2:
Move the
ADD ALT CHOP
switch to
ALT
or
CHOP
(In general,
it is better to use
CHOP
when the
SECIDIV
control is set in the millisec-
ond (ms) range, and
ALT
when the
SECIDIV
is in the microsecond (ps)
range.)
Step 3:
Position both signals on screen and adjust the vertical and
horizontal scales.
Adding Two Signals
Step 1:
Connect one signal to Channel
1
and the other signal to Chan-
nel
2.
Move the
CHI-BOTH-CH2
switch to
ADD.
Step 2:
Adjust the vertical position of the resultant display with both the
Channel
1
and Channel
2
POSITION
controls.
Subtracting Signals or Signal Components
(Common Mode Rejection)
You can subtract an undesirable DC or AC signal component by inverting it
in Channel
2
and adding it to Channel
1
(Figure 3-19).
