A better measurement tool

Specifically designed for use and direct connection to oscilloscopes with the TekVPI™ probe interface, the TDP1500, TDP3500 and TDP4000 Differential probes achieve high-speed signal acquisition and measurement fidelity by solving three traditional problems:

DUT loading effects - Are reduced by lower input capacitance and high input resistance
DUT connectivity - A variety of accessories exist for attaching to small SMDs, some come standard or recommended
Maximizing of system (oscilloscope and probe) bandwidth - Probing solutions for all measurements for TekVPI interface oscilloscope models up to 4 GHz
