Avoid damage to cable through excessive bending.
Handle with care. Tips of probe hooks are sharp. They puncture skin or cause other bodily
injury if not handled properly.
Keep fingers behind the finger guard of the probe hooks.
Do not operate with suspected failures. Before each use, inspect the probe and probe
hooks for any potential damage such as tears or other defects in the probe body, cable
jacket, accessories, etc. If any part is damaged, cease operation immediately and sequester
the probe from inadvertent use.
Introduction
The AP031 is a fully differential active probe designed for applications where electrical
signals must be measured relative to a floating voltage different to the oscilloscope ground
potential.
This probe is specifically designed for situations where:
The reference voltage may be several hundreds volts above or below ground.
Measurements require the rejection of common mode signals.
Ground loops and currents produce to excessive signal interference.
The use of the probe ensures safe operation of the oscilloscope and maintains high signal
fidelity with good common mode rejection and dynamic range.
The probe is a fully differential active device. The differential capability allows
measurements to be made between two points in a circuit without reference to ground.
The two input signals are processed inside the probe (see figure 1) and the resulting single-
ended signal may be measured by any grounded oscilloscope. Because the differential
