Multiple analog inputs are converted to respective multiple digital data records by analog to digital converters. A switch inserts a pseudorandom "alignment" code into each analog input at the beginning of conversion. After the analog to digital conversion, this pseudorandom code is detected by correlator filters to time align the plurality of digital data record with one another. The insertion of the pseudorandom code allows multiple analog inputs to be digitally converted in synchronization with one another. The disclosed logic controls its trigger timing and operation method.
