M8194A keysight Arbitrary Waveform Generator

The Keysight M8194A Arbitrary Waveform Generator (AWG) features up to four simultaneous channels operating in a single module with best-in-class sample rates and bandwidths.

• Arbitrary waveform generator offers superior speed, bandwidth, and channel density

• 1, 2 or 4 differential channels on a single-slot AXIe module to support optimized channel density

• 120 GSa/s sampling rate

• Capable of generating arbitrary signals with frequency components up to 50 GHz

• Cross-module synchronization

• 8-bit vertical resolution

• 512 kSamples per channel (PRBS 215-1 support)

The M8194A is also ideally suited to use any standard or custom data format, such as high-speed backplane connections using PAM-4 or PAM-8 formats, as well as technologies for mobile applications. The flexibility of generating waveforms at the highest speed and the excellent inherent jitter performance make the M8194A a truly future-proof instrument.

At data rates of several Gb/s, the impact of cables, board alignments, connectors, etc. must be accounted for in order to generate the required signal at the test point of the device under test. The M8194A uses digital pre-distortion technology with frequency and phase response compensated AWG outputs and any external circuitry to generate the required signal at the device under test. Channels can be embedded/de-embedded if the S-parameters of the individual circuits are provided. In combination with the 81195A optical modulator using the generator software various distortions can be added to the signal. With its high channel density, the M8194A is ideally suited to precisely stimulate multi-channel high-speed interfaces in an affordable manner.
