To activate the differential signals connected to channel 1 and channel 2,

follow these steps:

1. Press the CH 1 button and set the Probe option attenuation to 10X.

2. Press the CH 2 button and set the Probe option attenuation to 10X.

3. Set the switches to 10X on the probes.

4. Press the AUTO button.

5. Press the “MATH” button to see the Math Menu.

6. Press the “Operation” option button and select “－”.

7. Press the “CH1－CH2” option button to display a new waveform

that is the difference between the displayed waveforms.

8. You can adjust the vertical scale and position of the Math

waveform. To do so, follow these steps:

a. Remove the channel 1 and channel 2 waveforms from the

display.

b. Turn the CH 1 and CH 2 VOLTS/DIV and VERTICAL

POSITION knobs to adjust the vertical scale and position.

NOTE. First be sure to compensate both probes. Differences in probe

compensation appear as errors in the differential signal.
