Keysight delivers first 256 GSa/s Arbitrary Waveform Generator

Keysight has announced the first 256 GSa/s arbitrary waveform generator (AWG) - the M8199A - with 65 GHz analogue bandwidth in a compact 2-slot AXIe module.

Confronted with the growing demand for higher data transmission rates in telecom and data centres which has been driving transmission speeds to levels that are impossible to reach with the physical limitations of current test instruments, Keysight Labs has developed a new digital to analogue converter application specific integrated circuit (DAC-ASIC) that translates the memory data into an analogue signal.

In addition, the company has created a new package that avoids soldering sensitive radio frequency (RF signals), by placing an RF connector at the DAC-ASIC, so avoiding signal degradation. There is also a new breakthrough amplifier technology that can deliver high speed and quality output signals with a smooth frequency roll-off.

These new components have 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.

The M8199A 256 GSa/s AWG provides research engineers with a high performing signal source for arbitrary signals, enabling development of designs that push beyond the current limitations.

Whether testing the discrete components of an optical coherent transmission system or experimenting with terabit transmission for data centres, research engineers will require high sample rate, bandwidth, precision and flexibility to meet the challenges of these industry-leading applications.

Keysight claims that the M8199A 256 GSa/s AWG delivers twice the sampling rate of any AWG on the market today, coupled with at least 50 percent more analogue bandwidth. As a result, research engineers can quickly develop advanced components for terabit transmission systems.

"Keysight continues to invest in core test and measurement technologies, and we are happy to introduce the world's first 256 GSa/s AWG," said Brad Doerr, vice president and general manager of Keysight's Digital and Photonics Center of Excellence. "We are confident that the new M8199A will enable our customers to take the next step in the race for higher data transmission rates."

The M8199A AWG enables early research users to load waveforms, test pre-distortion algorithms, create stimuli for physics experiments and generate radar pulses of high modulation bandwidth.
