Abstract
A signal acquisition circuit for acquiring data of an input signal comprising at least n acquisition units, wherein n is integer greater than one, the n acquisition units comprising k inputs, wherein k is integer greater than one, and wherein at least two inputs are assigned to one channel and the corresponding acquisition units run time interleaved, and at least one trigger unit, wherein the number 1 of the at least one trigger unit is integer and wherein 1 is smaller than k. Further, a single-housed device as well as a method of acquiring data of an input signal are described.
Claims15
A signal acquisition circuit for acquiring data of an input signal, said signal acquisition circuit comprising:
- at least N acquisition circuits, wherein N is an integer greater than one, said N acquisition circuits comprising K inputs, wherein K is an integer greater than one, and wherein at least two inputs are assigned to one channel and the corresponding acquisition circuits run time interleaved, and
- wherein the signal acquisition circuit comprises only one trigger circuit, wherein the only one trigger circuit is a common trigger circuit,
- wherein at least two of the N acquisition circuits are operated in parallel, wherein the at least two acquisition circuits operated in parallel share the common trigger circuit such that data outputted by the respective acquisition circuits is directly forwarded to the common trigger circuit that applies a respective trigger on the data outputted by the respective acquisition circuits, and wherein the common trigger circuit is implemented on a single chip,
- wherein said signal acquisition circuit further comprises a signal bus connecting each of said N acquisition circuits with said only one trigger circuit such that data outputted by the N acquisition circuits is directly forwarded to said only one trigger circuit.
