Abstract

A digitizer system (DS) may include one or more input channels to receive sample data, and an acquisition state machine (ASM) to organize the sample data into one or more acquisition records according to events of interest, and generate framing information corresponding to the one or more acquisition records. The events of interest may be identified by a trigger circuit in the DS, and relayed to the ASM for organizing the sample data. The DS may further include a data interface capable of receiving the one or more acquisition records and the framing information, encoding the one or more acquisition records and the framing information into encoded data, and transmitting the encoded data to an expansion module. The expansion module may receive the encoded data, decode the encoded data, and recover the sample data from the decoded data according to the framing information and the one or more acquisition records.
