High-voltage differential probes

The TDP1000, TDP0500, and P6251 High-voltage Differential Probes are specifically designed for use with and direct connection to Tektronix oscilloscopes with either the TekVPI™ probe interface, or TekProbe BNC Interface. These probes achieve high-speed signal acquisition and measurement fidelity by solving three traditional measurement challenges:

  • Outstanding Electrical Performance
  • Versatile Device-Under-Test Connectivity
  • Ease of Use
