First 256-GS/sec arbitrary waveform generator features analog bandwidth exceeding 80 GHz

18 October 2022

The new M8199B arbitrary waveform generator (AWG) from Keysight Technologies provides R&D engineers a high-performance signal source for arbitrary signals that enables development of designs employing multi-level modulation formats (64QAM) at well beyond 160 GBaud.

Applications beyond 128 GBaud demand a new class of generators that provide high speed, precision and flexibility at the same time. Keysight addressed these challenges with the M8199B AWG, which offers a high performing signal source for arbitrary signals with sampling rate up to 256 GSa/s and analog bandwidth exceeding 80 GHz, including up to eight synchronized channels operating simultaneously.

The system provides research engineers the speed, bandwidth, precision and flexibility to meet theSource: Keysight TechnologiesSource: Keysight Technologies challenges of next-generation applications, enabling data transmission greater than 400 Gb/s per lane in intensity-modulation/direct-detect (IM/DD) and greater than 1.6 Tb/s per carrier in coherent optical communications.

For IM/DD and coherent optical applications, the system provides the flexibility needed for advanced research on new modulation formats to boost transmission rates to the next level. The M8199B AWG matches with high-speed research experimenting using multi-level pulse-amplitude modulation (PAM), quadrature-amplitude modulation (QAM) formats and other proprietary modulation formats at symbol rates approaching 200 GBaud. In addition, it provides stress signals to test next generation electro/optical components, digital signal processor application-specific integrated circuits (DSP-ASICs), and new algorithm concepts for multi-terabit transmissions systems.

In wideband radio frequency (RF) signal generation in wireless and aerospace/defense applications, the system addresses the latest developments in radar and wireless technologies that require generation of high-quality signals with modulation bandwidths well beyond 10 GHz. Generating those signals on an intermediate frequency (IF) rather than on quadrature signals is another important capability to support these applications.
