The Keysight M8199A is high performance Arbitrary Waveform Generator providing 4 channel 128 GSa/s or 2 channel 256 GSa/s sampling rates with up to 70 GHz analog bandwidth. It is ideal for coherent and direct detection signal generation.


  • 4 channel 128 GSa/s
  • 2 channel 256 GSa/s with interleaving
  • Up to 70 GHz bandwidth
  • 75 fs System jitter
  • 1.4Vpp differential amplitude @ 128 Gbaud
  • Built-in frequency and phase response calibration

The M8199A AWG delivers twice the sampling rate, coupled with 50 percent more analog bandwidth and increased ENOB compared to legacy AWG products. This combination of industry-leading specifications enables research engineers to quickly and accurately develop advanced components for terabit transmission systems.

The M8199A is the highest performing arbitrary waveform generator in the world, enabling signal generation of up to 140 Gbaud with outstanding signal quality in a 2-slot AXIe module. Whether testing the discrete components of optical coherent systems or pathfinding for terabit transmission in the next-generation data center, the M8199A is ideal for addressing the need for high sample rates and high analog bandwidth.
