The Keysight M8195A is a modular arbitrary waveform generator for high-speed electrical stimulus. The model family combines a maximum 65 GSa/s DAC rate, 25 GHz analog bandwidth, and 8-bit resolution in a one-slot AXIe format. Channel count and memory depend on installed options.

The Keysight M8195A creates electrical waveforms for digital receiver evaluation, coherent optical research, and wideband RF development. Its available one-, two-, and four-channel configurations support synchronized signal generation within one AXIe module.

Applications

• High-speed digital receiver testing with NRZ and multilevel waveforms.
• Coherent optical experiments using I/Q electrical stimulus.
• Wideband RF waveform generation for communications and radar development.

Configuration planning

Maximum sample rate, usable waveform memory, and channel count must be considered together. Extended-memory operation reads samples at lower rates in multichannel modes and uses interpolation to the DAC rate. An AXIe chassis and a controller or external computer are required; larger synchronized systems also require suitable synchronization hardware.

Confirm the installed channel licenses, memory option, chassis, controller, cables, and application software before selecting a system. Keysight supplies an M8195A firmware and soft-front-panel package that includes its IVI driver. The listed current software supports Windows 10 and Windows 11; compatibility with the supplied system still needs confirmation.
