Abstract

A signal analyzing circuit (24) is described, with at least a first channel (42), said first channel (42) comprising a digitizer (26) configured to digitize an input signal into a time-and-value-discrete signal; a switching unit (32) coupled to the digitizer (26), said switching unit (32) being adapted to receive said time-and-value-discrete signal and an acquisition memory (38) coupled to said switching unit (32). Said switching unit (32) is adapted to selectively activate a decimator unit (34) in a time-domain operation mode, said decimator unit (34) decimating said time-and-vale-discrete signal to a decimated time-and-value-discrete signal or a digital down converter unit (36) in a spectrum view operation mode, said digital down converter unit (36) down-converting said time-and-value-discrete signal to a down-converted time-and-value-discrete signal. Said acquisition memory (38) is coupled to said decimator unit (34) in said time-domain operation mode to store said decimated time-and-value-discrete signal, said acquisition memory (38) being not coupled to said digital down converter unit (36) in said time-domain operation mode. Said acquisition memory (38) is coupled to said digital down converter unit (36) in said spectrum view operation mode to store said down-converted time-and-value-discrete signal, said acquisition memory (38) being not coupled to said decimator unit (34) in said spectrum view operation mode. In addition, an oscilloscope (10) and a method for auto setting an oscilloscope (10) are described.
