Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A signal processing device comprising:
a signal input for receiving an input signal;
a first trigger unit configured to generate a trigger signal based upon a first trigger event in the input signal;
an acquisition memory for acquiring the input signal at least based upon the trigger signal so as to provide an acquired signal, the acquired signal being assigned to acquisition data stored in the acquisition memory;
a second trigger unit connected to the acquisition memory, said second trigger unit being adapted as a zone trigger unit applying a zone trigger;
at least one post-processing unit that relates to a measurement unit or an analysis unit; and
a display unit,
wherein the acquisition memory is located between the first trigger unit and the second trigger unit such that the second trigger unit located downstream of the acquisition memory is located between the acquisition memory and the at least one post processing unit, wherein an input of the second trigger unit is directly connected to an output of the acquisition memory, wherein an input of the at least one post-processing unit is directly connected to an output of said second trigger unit,
wherein said second trigger unit is adapted to receive the acquired signal from the acquisition memory and to process the acquired signal according to the zone trigger, the zone trigger being applied on the acquired signal originating from the acquisition memory such that the acquired signal is filtered according to a second trigger event in the acquired signal, wherein the second trigger unit is also adapted to generate a pre-processed signal that is forwarded to the at least one post-processing unit such that only those acquired signals are post-processed that fulfill the trigger condition of the zone trigger,
wherein the at least one post-processing unit directly receives the pre-processed signal that is output by the second trigger unit,
wherein no output from said second trigger unit is provided to the acquisition memory, said second trigger unit being configured to not affect the acquisition data stored in the acquisition memory and second trigger unit being configured to filter the acquired signal according to the second trigger event in the acquired signal such that only those acquired signals are post-processed by the at least one post-processing unit, which fulfill the trigger condition of the zone trigger,
wherein the acquired signal comprises signal tuples each having a first axis value and a second axis value, the first axis value being time or frequency, the second axis value being amplitude, and
wherein the zone trigger comprises the first axis range and the second axis range, the first axis range being associated with time or frequency, the second axis range being associated with amplitude, wherein said second trigger unit verifies whether or not the respective signal tuples lie within the first and second axis ranges set while applying the second trigger.
