  • Analog bandwidth up to 70 GHz
  • Continuous sample rate range at 100 to 128 GSa/s (4-channel), or at 200 to 256 GSa/s (2-channel)
  • Synchronization of up to 16 channels across 4 modules (128 GSa/s) or up to 8 channels across 4 modules (256 GSa/s)
  • Built-in frequency and phase response calibration for clean output signals
  • 6 bits ENOB, DC to 50 GHz, Fs 100 GSa/s
  • Intrinsic jitter: < 75 fs
  • Up to 1.4 Vpp differential output voltage @128 GBd
  • Transition time (20/80) as low as 5 ps
  • Channel-to-channel skew adjustment with 25 fs resolution
  • Synchronization of up to 16 channels across 4 modules
  • < 140 dBc wideband phase noise > 1 MHz
  • 512 KSa / 1 MSa of waveform memory per channel

Key Benefits of the New Arbitrary Waveform Generator

  • 4 channels at 128 GSa/s or 2 channels 256 GSa/s with up to 70 GHz nominal analog bandwidth
  • Provides research engineers a high-performance signal source for arbitrary signals, enabling development of designs up to 140 GBd
  • Keysight’s M8199A 256 GSa/s AWG delivers twice the sampling rate of any AWG on the market today, coupled with at least 50 percent higher analog bandwidth. As a result, research engineers can quickly develop advanced components for terabit transmission systems
  • Integrated, ready-to-use instrument
  • Operates with well-known software, like MATLAB or Keysight IQTools and
  • SCPI programming interface based on M8070B
  • High flexibility with upgrade options from 2 channels at 128 GSa/s to 4 channels at 256 GSa/s

Keysight’s M8199A arbitrary waveform generator (AWG) features four channels at 128 GSa/s or two channels at 256 GSa/s with up to 70 GHz nominal analog bandwidth.

As a high-performance arbitrary signal source, the M8199A enables the development of designs of 128 Gbaud and beyond, including advanced components for terabit transmission systems.

With up to 4 differential 128 GSa/s output channels per 2-slot AXIe module and the ability to synchronize up to 4 modules, the M8199A is well suited to stimulate multi-lane high-speed interfaces in an economic fashion.
