How to perform passive probe bandwidth compensation

The passive probe that comes standard with the oscilloscope is a high-impedance passive probe with data band compensation. The probe has a high-pass transmission circuit inside, while the oscilloscope has a low-pass circuit inside. Therefore, if you want to ensure more accurate test results, you need to perform bandwidth compensation when the probe is connected to the oscilloscope's input channel.

When compensating, you need to use the Probe Comp signal on the front panel of the oscilloscope to compensate, and compensate by adjusting the adjustable capacitor at the connection between the oscilloscope probe and the oscilloscope.
