Agilent HP Keysight M8196A 92 GSa/s Arbitrary Waveform Generator

The Keysight M8196A is a high-performance arbitrary waveform generator delivering 92 GSa/s sample rates across up to four synchronized differential channels. Purpose-built for optical, RF, and high-speed digital signal generation, it produces complex waveforms with 32 GHz analog bandwidth, 8-bit vertical resolution, and ultra-low intrinsic jitter. The instrument supports advanced modulation schemes including PAM-4, PAM-8, QPSK, and nQAM at baud rates exceeding 64 GBaud, making it essential for communication system development and validation.
