Model 2651A High Power System SourceMeter® Instrument Reference Manual
Example
-- Short sense LO and output LO terminals
-- Short sense HI and output HI terminals
-- Allow readings to settle, then get measurements
r0_hi, r0_lo = smua.contact.r()
-- Connect 50 OHM resistor between sense LO and output LO
-- Connect 50 OHM resistor between sense HI and output HI
-- Allow readings to settle, then get measurements
r50_hi, r50_lo = smua.contact.r()
smua.contact.calibratelo(r0_lo, Z_actual_lo, r50_lo,
50_ohm_actual_lo)
smua.contact.calibratehi(r0_hi, Z_actual_hi, r50_hi,
50_ohm_actual_hi)
