Abstract: Controlling a test instrument may include: determining a first value corresponding to power output by the test instrument; determining a second value based on the first value, where the second value corresponds to an amount of energy consumed by the test instrument; and placing at least part of the test instrument in a high-impedance state when the second value exceeds a threshold.

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.
