18.We used a Tektronix model TDS210 oscilloscope with model TDS2CM communications extension module.
19.The output resistance of the source is effectively in series with the nanocontact. On the tenth conductance step, the nanocontact resistance is so the shift due to a 50 Ω output resistance is 4%. The shift is correspondingly less for the lower conductance steps.
