Step 4. Contact check calibration
1. Short the Series 2600 sense low and output low terminals, as shown in Fig-
ure 16-4. Also short the sense high and output high terminals together, as
shown in the figure.
2. Allow the readings to settle, then get the Series 2600 readings:
r0_hi, r0_lo = smua.contact.r()
3. Connect a 50Ω resistor between the sense low and output low terminals, as
shown in
Figure 16-5. Also connect a second 50Ω resistor between the
sense high and output high terminals as shown in the figure.
4. Allow the readings to settle, then get the Series 2600 readings:
r50_hi, r50_lo = smua.contact.r()
5. Send the contact check low calibration command:
smua.contact.calibratelo(r0_lo,
Z_actual,r50_lo,50_ohm_actual)
Where: r0_lo = Series 2600 0Ω low measurement
Z_actual = actual zero value
r50_lo = Series 2600 50Ω low measurement
50_ohm_actual = actual 50Ω resistor value
Typical values:
smua.contact.calibratelo(r0_lo,0,r50_lo,50.15)
(Where r0_lo and r50_lo are measurements taken in steps 2 and 4
above.)
6. Send the contact check high calibration command:
smua.contact.calibratehi(r0_hi,
Z_actual,r50_hi,50_ohm_actual)
Where: r0_hi = Series 2600 0Ω high measurement
Z_actual = actual zero value
r50_hi = Series 2600 50Ω high measurement
50_ohm_actual = actual 50Ω 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.)
