TAP2500, TAP3500 and TAP4000 active probes for TekVPI™ probe interface

Selecting the right probe for your application is key to attaining the best signal fidelity in your measurements. Active probes provide truer signal reproduction and fidelity for high-frequency measurements. With our ultra-low input capacitance and unique interface, the TAP2500, TAP3500 and TAP4000 Single-ended Active FET probes provide excellent high-speed electrical and mechanical performance required for today's digital system designs.

Specifically designed for use and direct connection to oscilloscopes with the TekVPI™ probe interface, the TAP2500, TAP3500 and TAP4000 Active FET probes achieve high-speed signal acquisition and measurement fidelity by solving three traditional problems:

Lower DUT loading effects with ≤0.8 pF input capacitance and 40 kΩ input resistance
Versatile DUT connectivity for attaching to small SMDs
Preserves instrument bandwidth at the probe tip for up to 3.5 GHz oscilloscopes
