Teledyne LeCroy AP031 - 700 V, 25 MHz High-Voltage Differential Probe

High Voltage Differential Probe

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 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 and the resulting single-ended signal may be measured by any grounded oscilloscope. Because the differential voltage is calculated within the probe, with only the resultant difference signal being passed to the oscilloscope, a large dynamic range can be achieved with excellent rejection of common mode signals.
