Moku:Lab oscilloscope can be used to compensate a probe to ensure both accurate measurements of voltage and frequency and also precise waveform representation.
The Moku:Lab oscilloscope has an integrated waveform generator; the video shows the waveform generator being set to 1 kHz, 2 Vpp. The under-compensated signal is then adjusted to slightly over compensated and finally to a well compensated state. This is achieved with the probe in 10:1 setting; the Moku:Lab oscilloscope is also setup to 10x probe.

Under compensated; not true square waveform and amplitude measurement less than actual 2V. |
 |
Slightly over compensated, overshoot on leading edge and slight over measurement on amplitude of 2V actual |
 |
Accurately compensated, sharp square wave and accurate 2.000V amplitude measurement |
