Abstract
Systems and methods for testing a device under test (DUT) that includes a low power output driver. The methods include providing an input signal to the DUT. The low power output driver is configured to generate a data signal responsive to receipt of the input signal by the DUT and provide the data signal to a signal analyzer via a data signal transmission line. The methods further include determining an expected data signal to be received from the low power output driver and charging at least a portion of the data signal transmission line with a co-drive output signal that is based, at least in part, on the expected data signal. The methods further include receiving a composite data signal with the signal analyzer. The systems include probe heads with a plurality of data signal transmission lines and a plurality of co-drive conductors.
