14. Turn on the output:
smua.source.output = smua.OUTPUT_ON
15. Allow the readings to settle, then get both the multimeter and 2601B-PULSE current readings at the
negative zero value (the 2601B-PULSE measurement is not necessary if this step is being done on the
CALA sense). The two measurements should be made as close as possible in time. Use this command
for the 2601B-PULSE:
Z_rdg = smua.measure.i()
16. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
17. Set the source output to the negative full-scale value, for example:
smua.source.leveli = -90e-3
18. Turn on the output:
smua.source.output = smua.OUTPUT_ON
19. Allow the readings to settle, then get both the multimeter and 2601B-PULSE current readings at the
negative full-scale output value (the 2601B-PULSE measurement is not necessary if this 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 2601B-PULSE:
FS_rdg = smua.measure.i()
20. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
21. Send the source calibration command using the -range, -zero and -FS multimeter readings, and -zero
and -FS source values for the parameters:
smua.source.calibratei(-range, src_Z, DMM_Z_rdg, src_FS, DMM_FS_rdg)
Where:
= The negative of the present adjustment range
= The zero 2601B-PULSE source output value
= The zero DMM measurement
= The FS 2601B-PULSE source output value
Typical values for the 100 mA range:
smua.source.calibratei(-100e-3, -1e-30, -1e-6, -90e-3, -89.2e-3)
22. If this step is not on the CALA sense mode, send the measure calibration command using the
multimeter and 2601B-PULSE readings, and range setting for the parameters:
smua.measure.calibratei(-range, Z_rdg, DMM_Z_rdg, FS_rdg, DMM_FS_rdg)
Where:
= The negative of the present adjustment range
= The zero 2601B-PULSE measurement
= The zero DMM measurement
= The FS 2601B-PULSE measurement
Typical 100 mA range values:
smua.measure.calibratei(-100e-3, -1e-5, -1e-6, -91e-3, -89.2e-3)
