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.

Comparing Frequency and phase (Single X-Y Operation)
To compare the frequency and phase between two signals by using the
X-Y mode. The X-Y waveform displays different amplitude, frequency,
and phase. The figure 5-7 shows a typical waveform made up of two
signals that are of the same frequency and amplitude, but approximate
45 o out of phase.
To use the oscilloscope in the signal of X-Y mode, proceed the following
steps:
1. Connect the horizontal or X-axis signal to the CH1 input.
2. Connect the vertical or Y-axis signal to the CH2 input.
3. Set the CH1 off, and set the CH2 on.
4. Set the X-Y mode on by pressing and holding the button.
5. Set the TRIG SORCE button to CH1.
Use the HORIZONTAL POSITION control to adjust the X-axis.
Note: When high frequency signals are displayed in the X-Y
operation, note the frequency bandwidths and phase difference
between X and Y axis. Refer to “2. SPECIFICATION” section for
details.
