Oscilloscope Probe Offset Compensation
Oscilloscope Probe Offset Compensation
As the first step calibrating the Double-Pulse Test system, the oscilloscope
probes must be adjusted for low frequency compensation. For this, the 10076C
and N2873A passive probes have built-in compensation RC divider networks.
The N2819A Active Differential Probe requires offset compensation.
Required Equipment
All equipment required for compensation and calibration were provided with the
PD1500A test system. This includes:
Low Frequency Compensation for the 10076C and N2873A Probes
The Infiniium S-Series Oscilloscopes have a square wave reference signal
available on the front panel to use for compensating the passive probes. Attach
the spring hook and ground clip to the probe and then the square wave reference
terminal.

Keysight Double-Pulse Test System Installation Guide
Allow the oscilloscope and probes to warm up at ambient
temperature for a minimum of 60 minutes (1 hour) before
performing the adjustment.
– Spring hook and ground clips for passive oscilloscope probes.
– 5 cm Extension Leads and either Pincer or Micro IC clips for the N2819A
Differential probe.
– Low Frequency Compensation trimmer/adjustment tools (small
non-metallic screwdriver).
