1.5 GHz active probes for TekVPI™ probe interface

Specifically designed for use and direct connection to oscilloscopes with the TekVPI™ probe interface, the TAP1500 Active FET probe achieves high-speed signal acquisition and measurement fidelity by solving three traditional problems:
  • Lower DUT loading effects with ≤1 pF input capacitance and 1 MΩ input resistance
  • Versatile DUT connectivity for attaching to small SMDs
  • Preserves instrument bandwidth at the probe tip for ≤1 GHz oscilloscopes


All specifications are guaranteed unless noted otherwise. All specifications apply to all models unless noted otherwise.

Power requirements

The probe is powered directly by oscilloscopes with the TekVPI probe interface.
