Signal Generation and Probing Station in Action

The DAC (digital-to-analog converter) is responsible for signal generation. We have the advanced DAC (Micram) with 100GS/s sampling rate, 4 independent output channels, which can support dual-polarization QAM signal transmission up to 100Gbaud rate. The Micram DAC is programmable and enables different transmission rates, pulse shaping and channel pre-compensation.
