Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which a stimulation location in an electrode array is determined. Preferably, the supra-perception stimulation comprises a bipole formed using actively-driven symmetric biphasic waveforms at active ones of the electrodes in the array. After determining the location, a perception threshold for the bipole at the location is determined and stored, and an amplitude of the stimulation is reduced below the perception threshold to provide a sub-perception stimulation bipole. The determined perception threshold may be transmitted to the patient's remote controller, where it is used to limit amplitude adjustments to the sub-perception bipole by the patient.
