Probe Compensation
Proper compensation of the probe is required to assure amplitude accuracy of
the waveform being measured by matching the probe to the oscilloscope’s input
capacitance. Compensation should be adjusted whenever the probe is
connected to or transferred between oscilloscopes.
Low Frequency (PP019 and PP020)
1. Apply a 1 kHz square wave to the probe or connect to the oscilloscope’s
calibrator output.
2. Adjust the low-frequency trimmer located on the PP019/PP020 BNC
Compensation Box until you achieve a flat-topped square wave like the
center illustration in the second figure below.
