Adjustment procedure

The probe can be adjusted for low frequency (LF) compensation.

LF compensation is necessary whenever the probe is connected to a new oscilloscope input channel.

LF compensation matches the probe's series capacitance to the oscilloscope's input capacitance.

This matching assures good amplitude accuracy from DC to upper bandwidth limit frequencies. A

poorly compensated probe influences the overall system performance (probe + scope) and introduces

measurement errors resulting in inaccurate readings and distorted waveforms.

LF compensation is performed by connecting the probe to a suitable signal source such as:

• the CAL output on the oscilloscope front panel

• a good-quality 500 Hz square wave from the AWG output of a PicoScope

• a square wave output from an oscilloscope calibrator

and adjusting the LF compensation trimmer to obtain optimal square wave response. For examples

see figures below.
