4 Troubleshooting
To verify basic oscilloscope operation
1 Press the Save/Recall key on the front panel, then press the
Default Setup softkey under the display. The oscilloscope is
now configured to its default settings.
2 Connect an oscilloscope probe from channel 1 to the Probe
Comp signal terminal on the front panel.
3 Connect the probe’s ground lead to the ground terminal that
is next to the Probe Comp terminal.
4 Press AutoScale.
5 You should see a waveform on the oscilloscope’s display
similar to this:
If you see the waveform, but the square wave is not shaped
correctly as shown above, perform the procedure “To
compensate the analog probes” on page 65.
If you do not see the waveform, ensure your power source is
adequate, the oscilloscope is properly powered-on, and the
probe is connected securely to the front-panel analog channel
input BNC and to the Probe Comp terminal.
