A better measurement tool

Specifically designed for use and direct connection to oscilloscopes with the TekVPI™ probe interface, the TDP1500 Differential probe achieves 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 with 1.5 GHz
