Highlights

The Keysight M8296A is a four-channel, high-speed electrical digitizer module for the AXIe platform. It can synchronously sample up to four incident waveforms and digitize the output signals from a dual-polarization coherent receiver. Keysight’s vector signal analyzer and optical modulation analyzer software serve as the M8296A’s user interface. It enables many test and measurement tasks such as spectral analysis and digital demodulation to analyze signal quality metrics like error-vector magnitude. The platform stores and processes the sampled waveform using MATLAB.
 
The modular approach enables you to combine the M8296A high-speed digitizer in one mainframe using a Keysight M8292A modular optical modulation analyzer and the Keysight M8196A 92 GSa/s arbitrary waveform generator. Integrated coherent receiver (ICR) modules are key components in coherent transmission systems. They are more challenging to test because the ICRs have phase-sensitive signal detection and provide four electrical outputs and two optical inputs. 
 
The M8296A electrical high-speed digitizer connects to the four differential outputs of an ICR and enables the quick set up of parametric tests. In combination with two tunable lasers, a polarization synthesizer, and the optional ICR test software, the M8290A solution measures:
 
  • S21 magnitude response of all detection paths
  • IQ skew, XY skew, IQ angle
  • IQ and XY gain imbalance
  • EVM noise floor
  • image suppression
