1. A method for measuring and representing the measured value of a limit in terms of another measurement in a signal measurement system, the method comprising the steps of: developing a master application layer that provides necessary infrastructure for a client application to plug-in the implementation for dynamic limits and units; sending required details to the client application by the master application layer; allowing the client application to make limit calculations; processing and representing values obtained after the limit calculations in terms of another measurement; and sending said values back to the master application layer for display.
