GW Instek GDP-025 - Active differential probe for oscilloscopes. Enables measuring differential signals with a standard oscilloscope. A standard oscilloscope probe measures potential relative to ground, but the GDP-025 differential probe allows measurements between two freely selectable potentials. The probe is capable of measuring voltages up to 1400V.
