Abstract
A system and a method for testing a high-speed ADC in a DP-QPSK receiver are disclosed. The system includes a simulation module for outputting a data flow and performing signal recovery, an arbitrary waveform generator for receiving the data flow and outputting a high-speed analog signal and a clock signal, a high-speed ADC for converting the high-speed analog signal and the clock signal into a high-speed digital signal, a cache memory circuit for converting the high-speed digital signal into a low-speed digital signal, and a logic analyzer for sending the low-speed digital signal to the simulation module.
