Teledyne LeCroy AP031 Oscilloscope Probe, Differential Type, 25MHz, 1:10, 1:100, BNC Connector

The Teledyne LeCroy is an active oscilloscope probe that is intended for measuring high voltages. The differential techniques employed permit measurements to be taken at two points in a circuit without reference to the ground, allowing the oscilloscope to be safely grounded without the use of optoisolators or isolating transformers.
