Analysis of oscilloscopes by PC
By Maryjane Hayes; Agilent Technologies, Inc.
Engineers have long used oscilloscopes to debug and test their designs. To view the signals to be measured, it is necessary to have exclusive access to a given oscilloscope, which in turn prevents other users from using it. This situation can be a problem in the case of those devices shared by a team, since only one of its members will be able to use the oscilloscope and the resulting measurements at any given time. In the case of teams whose members are dispersed locally or globally, it is one of its members who usually makes the measurements with the oscilloscope and sends an image of the screen to another member of the team for analysis. Often, these experts would like to see what happened before and after the moment captured by said image. Your efforts to perform additional analysis are thwarted by the fact that the measure is just a picture, with no underlying raw data.
