This is the first co-contributed eBook with articles from both Microwave Journal and Signal Integrity Journal as the versatile oscilloscope is used for measurements for wireless and high-speed circuits.

Compliance testing is essential to ensure that dynamic random access memory (DRAM) signals meet specifications in timing, slew rates and voltage levels. To quickly check signal qualities, eye diagram testing can provide insights into signal integrity conditions in a much shorter time.

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.

The R&S ZNBT40 is the first vector network analyzer (VNA) with a broad frequency range from 100 kHz to 40 GHz and up to 24 integrated test ports.
