It is not necessary to set the measure range when following this procedure for calibration because
the measure range is locked to the source range when measuring the source function.
C. Perform each calibration adjustment for the voltage source and measure function step listed in
Step sequence (on page 10-18) as follows:
1. Select the range being calibrated with this command:
smua.source.rangev = range
2. Select the correct sense mode based on the calibration step for the voltage source and measure
function from the Step sequence (on page 10-18), for example:
smua.sense = smua.SENSE_LOCAL
3. Select positive polarity, and then set the source output to the positive zero value. For example:
smua.cal.polarity = smua.CAL_POSITIVE
smua.source.levelv = 1e-30
4. Turn on the output:
smua.source.output = smua.OUTPUT_ON
5. Allow the readings to settle, then get both the multimeter and 2600B voltage readings at the positive
zero value (the 2600B measurement is not necessary if this calibration step is being done on the CALA
sense mode). The two measurements should be made as close as possible in time. Use this command
for the 2600B:
Z_rdg = smua.measure.v()
6. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
7. Set the source output to the positive full-scale value for the present range, for example:
smua.source.levelv = 0.9 (Model 2601B, 2602B, or 2604B)
smua.source.levelv = 1.8 (Model 2611B, 2612B, 2614B, 2634B, 2635B, 2636B)
8. Turn on the output:
smua.source.output = smua.OUTPUT_ON
9. Allow the readings to settle, then get both the multimeter and 2600B voltage readings at the positive
full-scale output value (the 2600B measurement is not necessary if this calibration step is being done on
the CALA sense mode). The two measurements should be made as close as possible in time. Use this
command for the 2600B:
FS_rdg = smua.measure.v()
10. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
