Overview
A high-voltage differential probe measures the voltage difference between two points when neither is at ground. Tektronix high-voltage differential probes support floating, isolated and non-ground-referenced measurements with strong common-mode rejection and model-dependent maximums up to ±6000 V.

Tektronix High Voltage Differential Probe solutions offer

• Best-in-class bandwidth and optimized probe loading for oscilloscope inputs
• Third-party safety certifications (UL, CSA, ETL) for applicable models
• Range of high- and medium-voltage models to match dynamic range and resolution needs
• Extensive accessory ecosystem for adapter and power supply compatibility

Notes on compatibility and accessories (extracted)

• Certain probe models require adapters or external power supplies for specific oscilloscope families; adapter and TekVPI® external power supply requirements vary by oscilloscope model.
• High-frequency models may vary input impedance and input capacitance to optimize signal fidelity for particular oscilloscope inputs.

Technical specifications / Key characteristics

• Intended use: differential measurements where neither test point is at ground; floating or isolated measurements.
