Helping you develop your innovation

Keysight knows you are pushing boundaries and understands that your innovation requires next generation test equipment. That’s why we continually develop solutions that keep up with the latest technology waves and applications. The M8199B Arbitrary Waveform Generator (AWG) is the latest example of this commitment.  

Fastest AWG on the market

The Keysight M8199A AWG uses an external passive coupler to interleave two 128 GSa/s channels to achieve signal generation up to 256 GSa/s. The M8199B AWG follows the same interleaving approach as the M8199A, but the passive combiner and RF amplifier are integrated into a single package, greatly improving the achieved bandwidth and signal-tonoise ratio (SNR).

The Keysight M8199B AWG offers you performance never seen before. It has a built-in frequency and phase response calibration, which ensures generating the most accurate signal possible. It is ready to use out-of-thebox, which means you spend less time setting up your test equipment and more time running your tests. Brand-new Keysight custom technology ensures highest signal quality and maximum flexibility.

Support for leading-edge applications

The M8199B AWG allows you to generate signals up to 256 GSa/s with sufficient signal integrity, perfect for applications like 1.6 Tb/s coherent transmissions or beyond 224 Gbit/s/lane intensity-modulation/direct-detect (IM/DD) transmissions.

The M8199B AWG is the unique solution in the market allowing R&D teams in the telecom and datacom industry, developing components, prototypes or products for coherent and IM/DD optical transmission systems operating at data rates up to 160 GBaud and beyond.

The M8199B AWG provides a stimulus signal with flexible modulation schemes (NRZ, PAM-n, QPSK, QAM-n). In addition, it allows you to apply offline customized digital-signal processing before loading the signal into the memory of the AWG.

Design

PAM4 system analysis

Keysight has a full PAM4, E-O-E (Electrical – Optical – Electrical) end-toend link simulation example in PathWave ADS 2020, including modeling of the optical channel using VPIphotonics’ VPItransmissionMaker™. The connected solution to FlexDCA feature allows fast and accurate insights of PAM4 measurements and comparison with measured results including transmitter dispersion and eye closure quaternary (TDECQ).

Facing today’s high-speed design challenges.

When digital signals reach multigigabit speeds, the unpredictable becomes the norm. Keysight’s PathWave ADS will help you cut through these challenges by state-of-the art high speed digital design simulation solutions. PathWave ADS delivers industry leading time-, frequencydomain, and channel simulation technologies, within a cohesive design-totest workflow, to help you overcome signal integrity and power integrity issues for SerDes and memory interface designs, while ensuring the design for compliance.
