Keysight delivers first 256 GSa/s arbitrary waveform generator with 65 GHz analog bandwidth

11/06/2020

Keysight Technologies, Inc. announced the first 256 GSa/s arbitrary waveform generator (AWG) – Keysight's M8199A - with 65 GHz analog bandwidth in a compact 2-slot AXIe module.

The growing demand for higher data transmission rates in telecom and data centers is driving transmission speeds to levels that are impossible to reach with the physical limitations of current test instruments. A creative approach was needed to extend rates towards theoretical limits and meet the needs of next generation transmission.

Keysight addressed this challenge by targeting the specific needs of engineers working on the fastest, most complex signals the industry has ever seen. As a result, Keysight Labs developed a new digital to analog converter application specific integrated circuit (DAC-ASIC) that translates the memory data into an analog signal. In addition, the company created a new package that avoids soldering sensitive radio frequency (RF signals), by placing an RF connector at the DAC-ASIC, thus avoiding signal degradation, plus a new breakthrough amplifier technology to deliver high speed and quality output signals with a smooth frequency roll-off.

These new components resulted in the industry's first AWG that allows 256 GSa/s with a useable signal bandwidth beyond the nominal 65 GHz even up to 80 GHz.
