P3010 High-Frequency Compensation - Tektronix TDS3012C User Manual

P3010 High-Frequency Compensation

The P3010 high-frequency compensation should seldom require
adjustment. However, your probe may require high-frequency
adjustment if either of the following are true:
The probe has high-frequency aberrations
The probe does not perform at the rated bandwidth
To perform the high-frequency compensation adjustment, you will need
a signal source that has all of the following characteristics:
Square-wave output at 1 MHz
Fast rise output with rise time less than 1 ns
Output properly terminated
Connect the P3010 to the signal source to display a 1 MHz test signal
on your oscilloscope. Use the BNC-to-probe tip adapter (013-0277-00)
to make the connection. The oscilloscope should display a waveform
similar to the one shown next.
Adjust trimmer H until the waveform is flat on top and has a square
leading edge.
