I think you have to ask EMCO, because that horrible dBS/m ( S = siemens) is mathematically unsound (don't ask) and is dB (amps/volts)/m, whereas picotesla only involves current, distance and the permeability of space, not voltage.
This does assume that everyone is using the correct units and the correct abbreviations. With best wishes DESIGN IT IN!

The customer has requested an extended magnetic field emission test over the range 100kHz to 2MHz with a limit defined in dBpT. The antenna to be used is an EMCO 6512 which has it correction factors provided in dBS/m which the emission software used does not recognise. So is there a conversion factor that enables the right correction factor to be entered or is the conversion factor only used once a result is obtained??
