When analyzing the signal integrity performance of DDR interfaces, separating read and write cycles has been a challenging task. Comprehensive trigger capabilities are required – especially when attempting to recreate the eye diagram in realtime. Reliably separating read and write cycles is crucial for evaluating the signal integrity of DDR memory interfaces. The digital trigger of the R&S®RTP high-performance oscilloscope ensures a precise sequential trigger mechanism. This, combined with the zone trigger, offers versatile and flexible triggering capabilities for DDR memory interface measurements.
