Abstract
A measuring system has an analog-to-digital converter, an acquisition memory, a processing unit, and a display memory. The processing unit is adapted to decode a digital signal according to a protocol creating a decoded signal and to evaluate the decoded signal at a cursor position. The digital data generated by decoding the decoded signal at the cursor position is stored in the display memory. Further, a method for analyzing an analog signal according to a protocol is shown.
Claims21
A measuring system, comprising:
- an analog-to-digital converter configured for converting an analog signal into a digital signal;
- an acquisition memory configured for storing said digital signal;
- a processing unit configured to decode said digital signal according to a selected protocol in order to create a decoded signal, the processing unit further configured to store said decoded signal;
- a display memory;
- and
- a display configured to display a visualization of said digital signal and a visualization of said decoded signal, wherein said visualizations of said digital signal and said decoded signals are provided over time or use the same timescale,
- wherein said processing unit is further configured to evaluate said decoded signal at a time associated with a cursor position and generate representative digital data based on said decoded signal at said time associated with said cursor position, and configured to store said representative digital data in said display memory.

A method for analyzing an analog signal using a measuring system, comprising:
- converting, by an analog-to-digital converter, said analog signal into a digital signal;
- storing said digital signal in an acquisition memory;
- decoding, by a processing unit, said digital signal according to a selected protocol thereby creating a decoded signal;
- displaying, by a display, a visualization of said digital signal and a visualization of said decoded signal, wherein said visualizations of said digital signal and said decoded signals are provided over time or use the same timescale;
- evaluating said decoded signal at a time associated with a cursor position and generating digital data representative of said decoded signal at said time associated with said cursor position;
- and
- storing said digital data of said position in a display memory of said measuring system.
