Abstract
An oscilloscope includes a signal input circuit, a switching matrix circuit, and a downconverter circuit. The signal input circuit is configured to receive M input signals, wherein at least one of the input signals is a signal comprising at least two carriers. The switching matrix circuit is configured to selectively forward at least one input signal from at least one of the switching matrix inputs to the switching matrix outputs. The downconverter circuit includes a local oscillator and at least two downconverter sub-circuits. The at least two downconverter sub-circuits are configured, for example, to: down-convert a first signal component of the signal that is associated with a first one of the least two carriers based on a local oscillator signal and down-convert a second signal component of the signal that is associated with a second one of the least two carriers based on the local oscillator signal, respectively.
