Testing and characterizing jitter in 100BASE-TX and 155.52 Mbit/s ATM devices with a 1 Gsamples/s AWG in an ATE system

An ATE system uses a phase-synchronous 1 Gs/s AWG to input waveforms, representing high-speed data communications signals degraded by twisted-pair cable, into a 100BASE-TX and 155.52 Mbit/s ATM transceiver. A phase-synchronous Digital Capture Port captures the resulting received data outputs. The captured waveforms are statistically analyzed to measure various modes of jitter.
