Electrical Validation and Debug

DDR Memory Interface

Electrical Validation

Electrical validation solutions allow you to capture, measure and characterize DDR memory interfaced signal behavior, jitter, eye size, crossover, strobes/clock alignment and bit errors confidently with the MSO/DPO70000 Series of oscilloscopes that provide high waveform capture rates combined with sophisticated tools like Pinpoint Triggering, Visual Triggering and Advanced Search and Mark capabilities.

Probing solutions for P7500 Tri-mode and P7300 differential high-bandwidth probes combined with a wide variety of interposers provide access to those hard to reach signals.

Our memory signal analysis package supports all popular memory standards such as DDR1/2/3/4, LPDDR1/2/3/4, GDDR3/5 and automatically identifies and performs gated measurements on the acquired data to provide a comprehensive report that includes pass/fail results.
