To test the 54621D/22D Oscilloscope digital channels

Only the 54621D/22D Mixed-Signal Oscilloscope has Digital Channels

You need to perform these instructions only if you will be testing the digital channels on the Agilent 54621D/22D Mixed-Signal Oscilloscope.

The acquisition system testing provides confidence that the acquisition system is functioning correctly. It does not, however, check a particular specification.

1Disconnect all probes from the circuit under test and from any other input source.

2Using probe leads and grabbers, connect digital channels D0, D1, D2, and D3 to the calibration point on the 54621D/22D front panel.

3Press the Autoscale key.

If four square waves appear, the acquisition system is functioning correctly.

If the square waves do not appear, go to the “Troubleshooting” chapter. Then return here to finish testing the digital channels.

4Disconnect the digital channels from the calibration point.

5Use steps 2 and 3 to test the following sets of digital channels. After you test one set of digital channels, remove them before connecting the next set.

D4, D5, D6, D7

D8, D9, D10, D11

D12, D13, D14, D15
