Model 2657A High Power System SourceMeter® Instrument Reference Manual
Section 7: TSP command reference
2657A-901-01 Rev. B/December 2012
7-189
Example
-- Short SENSE LO and LO terminals
-- Short SENSE HI and HI terminals
-- Allow readings to settle, then get measurements
r0_hi, r0_lo = smua.contact.r()
-- Connect 50 OHM resistor between SENSE LO and LO
-- Connect 50 OHM resistor between SENSE HI and 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)
Performs contact
check on SMU
channel A.
Install and measure
two resisters.
The user sends
contact check LO
calibration
command.
The user sends
contact check HI
calibration
command.
