Achieve High Speed, Multichannel Data Acquisition with the Agilent M9703A AXIe Digitizer Challenge the Boundaries of Test Agilent Modular Products

In many multichannel high speed data acquisition applications, such as radar, satellite (beam-forming), MIMO, or high-energy experiments, it is critical to have phasecoherent channels for accurate data acquisition whether for demodulation, antenna calibration, channel sounding, or event capture. Large-scale experiments may require the use of tens or hundreds of synchronized channels, and very precise time correlation between channels. Therefore, synchronization across multiple instruments is primordial. This application note describes the measurement and analysis of cross channel skew in multichannel high speed digitizers over short and long durations to sub-picosecond scales. Two measurement techniques using the Agilent M9703A High Speed Digitizer are described and compared, and the results presented.
