SPR-002 issue 2 introduced new more demanding probe requirements for Nerve Stimulation (NS) testing. These same probe requirements are available in the lately published RSS-102.NS.MEAS. The separation distance is defined between the probe antenna and the Equipment Under Test (EUT) and the probe antenna size shall be sufficiently small to ensure accurate measurements. The NS measurements at 0mm separation distance may now require extrapolation to the probe enclosure to fulfill this requirement.  

Due to the smaller size of the probe antenna, sensor arrangement and extrapolation the measured instantaneous electric and magnetic field values are expected to be higher compared to measurement probes that were accepted in SPR-002, issue 1.
