Abstract

A signal analyzer for analyzing an input signal comprises at least one input for receiving the input signal, at least one acquisition unit for acquiring data assigned to the input signal, an acquisition memory for storing the acquired data, the acquisition memory being adapted to store data in at least one ring buffer, and an acquisition memory controller to control at least one of writing the acquired data in the acquisition memory and reading the acquired data from the acquisition memory. The acquisition memory controller comprises a data read module for reading data of the at least one ring buffer. The acquisition memory controller comprises a copy write module which taps data read by the data read module. The acquisition memory comprises an additional memory section. The copy write module is configured to write the data tapped into the additional memory section. Further, a method of processing data from an input signal is described.
