Patent ID: 7683630

Claim:
In an electrical test system for providing a power source to each of a plurality of electrical components under electrical test, the test system to be in electrical contact with each electrical component to be tested by measuring at least one voltage value and at least one current value for each electrical component under electrical test, the improvement comprising: at least one programmable voltage source coupled to a respective voltage output channel; at least one programmable current source coupled to a respective current output channel; a controller configured to program a voltage source of the at least one programmable voltage source to deliver a programmed voltage value to its respective voltage output channel and to independently program a current source of the at least one programmable current source to deliver a programmed current value to its respective current output channel; random access, non-volatile, memory for storing information and for providing read/write interface capability for the controller; at least one digital/analog converter for communicating between the controller and the programmable voltage and current sources; and a host computer in communication with the controller for running a self test program to set at least one programmable value and to receive back a measured value to test at least one complete subsystem through the controller to determine if the tested complete subsystem is operating properly.
