To compensate the analog probes

78
If you see the waveform, but the square wave is not shaped
correctly as shown above, perform the procedure
compensate the analog probes"
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.
6 If you still do not see the waveform, use the troubleshooting
flowchart in this chapter to isolate the problem.
You should compensate your analog probes to match their
characteristics to the oscilloscope's channels. A poorly
compensated probe can introduce measurement errors.

2 Use a nonmetallic tool to adjust the trimmer capacitor on the
probe for the flattest pulse possible. The trimmer capacitor is
located on the probe BNC connector.
