Title: COMBINING CURRENT SOURCED BY CHANNELS OF AUTOMATIC TEST EQUIPMENT
Abstract:
An example test system includes: multiple channels, where each of the multiple channels is configured to force voltage and to source current; and circuitry to combine current sourced by the multiple channels to produce a combined current for output on a single channel to a device under test (DUT), where each of the multiple channels includes a load sharing resistor to control a contribution of the channel to the combined current.
