ABSTRACT:
The present invention relates to a measurement system for characterizing device performance comprising a set of generating and measuring instruments which are connected to a controller via a data bus. The instruments provide the necessary bias and RF signals to the device and concurrently measure its performance. Primarily three functions are provided: (a) establishment of a desired input signal by the user or the controller and the monitoring in real time of the device performance, (b) taking of a set of measurements and interpreting the measurements to characterize the device performance, and (c) displaying the measured and interpreted data for immediate study and the recording thereof for subsequent use. The automated capability permits a user to tune a device and simultaneously optimize its parameters.
