P6900 series probes
The DDR memory interface has evolved to support higher data rates at lower voltages creating several debug and validation challenges. With the industry's lowest capacitance, the P6900 specialty probes for DDR Memory applications offer excellent signal integrity to ensure a true representation of the signal - critical for connecting to high-speed memory interfaces and performing debug and analysis.
Probes with a variety of attachment mechanisms for different applications are available. Where circuit board space is at a premium, the high-density P6960DBL and P6962DBL probes with D-Max® Probing Technology offers the industry's smallest available footprint. For use with interposers, the P6960HCD, P6960HCD-LV and P6962HCD offer a low profile connection mechanism making it mechanically easy to use with the interposers. For low signal swing application the P6960HS based on the D-Max® Probing Technology is suitable.
For debugging the signal integrity problems common on high-speed DDR buses, the P6900 specialty probes for DDR applications work with the TLA7Bxx modules to provide iCapture™ simultaneous digital-analog acquisition. This allows you to clearly see the time-correlated digital and analog behavior of your design, without the extra capacitance and setup time of double probing.
