Abstract: A heating, ventilation and air conditioning (HVAC) system is provided. The system includes an integrated motor including a plurality of operating speeds and an input for selecting one of the plurality of operating speeds. The system further includes a system controller and an adjustment module. The adjustment module includes a plurality of operating modes each associated with one of the plurality of operating speeds and the ability to manually vary associations between the plurality of operating modes and the plurality of operating speeds. The adjustment module selects one of the plurality of operating modes on the basis of control commands received from the system controller and setting programmed or manually entered into and stored in the adjustment module and controls the integrated motor according to the operating speed associated with the selected operating mode.

Abstract: Provided is a method and system for diagnosing a test system to determine whether a condition of the test system contributed to an undesirable measurement result. The method includes interrogating a device under test comprising at least one of transmitting an electric signal to energize a device under test by the test system and conducting a passive measurement that does not require the device under test to be energized to be performed to determine if the device under test satisfies a design parameter. The method further includes processing an output signal including at least one of a responsive electric signal transmitted from the device under test in response to being energized and a passive signal corresponding to the passive measurement, and comparing a value of a property of the output signal to a reference value. Responsive to the comparing, the method determines whether the value of the output signal is within an acceptable tolerance of the reference value.

Abstract: A test head for testing a DUT includes a probe card having a plurality of DUT probes, the probes being in contact with the DUT during the testing; an instrument carrier, the instrument carrier being located above the DUT during the testing; and a SMU mounted on the carrier for each of the probes, each SMU being operably connectable to a respective probe, wherein the carrier is moved with respect to the probe card to permit replacement of the probe card.
