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
