 - Integrated Scope/Probe system
- Direct connection to and powered from the TekVPI™ oscilloscope interface (Connects directly to TekVPI scopes without the need of an external power supply, like many competitors require)
 - Single-button oscilloscope probe menu access
 - Setup and control from probe comp box or oscilloscope user interface
 - AutoZero - zeros out output offset
 Remote GPIB/USB probe control through the oscilloscope
 
Applications
- Design, validation, debugging, and characterization of common high-speed serial bus designs:
- I 2C
 - CAN/LIN
 - SPI
 - Serial ATA
 - Ethernet (GbE)
 - USB 2.0
 - FIreWire (1394b)
 
 - Signal integrity, jitter, and timing analysis
 - Manufacturing, engineering, and test
 

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
