Various embodiments relate to a device to analyze an implantable neural stimulation system that includes an implantable neural stimulation lead for an implantable neural stimulator to be implanted into a patient. Various device embodiments comprise an external housing, a pacing circuit in the housing, and a sensing circuit in the housing. The pacing circuit is adapted to deliver a test neural stimulation signal. At least one test lead cable is adapted to electrically connect the pacing circuit and the implantable neural stimulation lead to enable the test neural stimulation signal to be delivered to a neural target through the test lead cable and the implantable neural stimulation lead. At least one physiological sensor is adapted to sense a physiological response to stimulation of the neural target. At least one sensor cable is adapted to electrically connect the sensing circuit and the at least one physiological sensor.
