A system and method: receive an input signal and output digital samples representing the input signal; store the digital samples for at least one acquisition record of the input signal in an acquisition memory; detect a trigger event in the input signal and calculate a trigger address in the acquisition memory for a digital sample corresponding to the detected trigger event; perform digital signal processing on the digital samples of the acquisition memory to produce processed digital samples; detect an edge, representing a trigger, in the processed digital samples, and determine a measured trigger time; temporarily store the processed digital samples in a buffer memory at least until the edge detector detects the edge in the processed digital samples; determine a trigger correction value in response to the measured trigger time; determine a corrected beginning address of the buffer memory from the calculated trigger address and the trigger correction value; and read the processed digital data out from the bu
