The AP031 / AP032 are fully differential active probes designed for applications where electrical signals must be measured relative to a floating voltage different to the oscilloscope ground potential.

• 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 these probes ensures safe operation of the oscilloscope and maintains high signal fidelity with good common mode rejection and dynamic range.
