Abstract

A test and measurement device is described that includes a radio frequency input for receiving a radio frequency signal, a mixer to mix the radio frequency signal into a first intermediate frequency signal, a splitter to split the first intermediate frequency signal into several split signals, several signal paths for processing the several split signals, and a recombiner that is configured to recombine the split signals in order to create an output signal having a frequency span substantially representing the one of the radio frequency signal. Further, a method for calibrating a test and measurement device and a method for analyzing a high bandwidth of a radio frequency signal are described.
