NOTE.

Be sure to

fi

rst compensate both probes. Differences in probe

compensation appear as errors in the differential signal.

To activate the differential signals connected to channel 1 and to channel 2,
follow these steps:

1.

Push the

1

(channel 1 menu) button and set the

Probe

►

►

Attenuation

option to

10X

.

2.

Push the

2

(channel 2 menu) button and set the

Probe

►

Voltage

►

Attenuation

option to

10X

.

3.

If using P2220 probes, set their switches to 10X.

4.

Push the

Autoset

button.

5.
