Figure 20-4
Connections for contact check 0Ω calibration
b. Allow the readings to settle, then get the Series 2600A readings:
r0_hi, r0_lo = smua.contact.r()
c. Connect a 50Ω resistor between the sense low and output low terminals, as shown in
Figure 20-5. Also connect a second 50Ω resistor between the sense high and output
high terminals as shown in the figure.
d. Allow the readings to settle, then get the Series 2600A readings:
r50_hi, r50_lo = smua.contact.r()
e. Send the contact check low calibration command:
smua.contact.calibratelo(r0_lo, Z_actual,r50_lo,50_ohm_actual)
Where: r0_lo -- Series 2600A 0W low measurement
Z_actual -- actual zero value
r50_lo -- Series 2600A 50W low measurement
50_ohm_actual -- actual 50W resistor value
Typical values:
smua.contact.calibratelo(r0_lo,0,r50_lo,50.15)
f. (Where r0_lo and r50_lo are measurements taken in steps 2 and 4 above.)
g. Send the contact check high calibration command:
smua.contact.calibratehi(r0_hi, Z_actual,r50_hi,50_ohm_actual)
Where: r0_hi -- Series 2600A 0W high measurement
Z_actual -- actual zero value
r50_hi -- Series 2600A 50W high measurement
50_ohm_actual -- actual 50W resistor value
Typical values:
smua.contact.calibratehi(r0_hi,0,r50_hi,50.15)
(Where r0_hi and r50_hi are measurements taken in steps 2 and 4 above.)
