PP019/PP020 Passive Probe
High Frequency (PP020 only)
High frequency should rarely require adjustment. However, if adjustment is
required:
1. Apply a 1 MHz square wave to the probe (< 0.7 ns rise-time).
2. Remove the plastic caps from the two, high-frequency trimmers on the
PP020 BNC Compensation Box.
3. Adjust HF2 then HF1 until you achieve a flat-topped square wave like the
center illustration in the second figure below.
