Rigol PVP3150 - 150 MHz Passive Probe with 1x:10x Selector

Frequency Compensation

Before taking any measurement using a probe, first check the frequency compensation of the probe and adjust it to match the oscilloscope used. Generally, the oscilloscope provides a calibration signal output terminal at the front panel. Connect the probe (set the probe attenuation to 10X) to the signal output terminal to display a square waveform on the oscilloscope. Insert the adjustment tool into the compensation adjustment hole at the probe head and rotate it clockwise/counterclockwise until the properly compensated square waveform is displayed (flat-top square waveform).
