E. Allow the readings to settle, then get the 2601B-PULSE readings:
r50_hi, r50_lo = smua.contact.r()
F. Send the contact check low calibration command:
smua.contact.calibratelo(r0_lo, Z_actual, r50_lo, 50_ohm_actual)
Where:
2601B-PULSE 0 Ω low measurement
Actual zero value; the resistance of the short between the SENSE LO and
LO terminals
2601B-PULSE 50 Ω low measurement
Actual 50 Ω resistor value; the actual value of the resistor between the SENSE
LO and LO terminals
Typical values:
smua.contact.calibratelo(r0_lo, 0, r50_lo, 50.15)
Where r0_lo is the same value as measured in step B, and r50_lo is the same value as
measured in step E.
