C. Perform each step listed in the step sequence for the 250 mA range as follows:
1. Characterize the resistor.
2. Reset the instrument.
3. Set the High-Z output-off mode.
smua.reset()
smua.source.offmode = smua.OUTPUT_HIGH_Z
4. Select the range being adjusted:
smua.pulser.rangev = 5
smua.pulser.rangei = 5
5. Enable the pulser.
smua.pulser.enable = 1
6. Select positive polarity, then set the bias source output to the positive zero value:
smua.cal.polarity = smua.CAL_POSITIVE
smua.source.leveli = 2.5e-3
7. Turn on the output:
smua.source.output = smua.OUTPUT_ON
8. Allow the readings to settle.
9. Get the multimeter and 2601B-PULSE current readings at the positive zero value. The two
measurements should be made as close as possible in time. Use this command for the 2601B-PULSE:
Z_rdg = smua.measure.i()
10. Turn off the output and disable the pulser:
smua.source.output = smua.OUTPUT_OFF
smua.pulser.enable = 0
11. Set the source output to the positive full-scale value for the present range:
smua.source.leveli = 225e-3
12. Enable the pulser and turn on the output:
smua.pulser.enable = 1
smua.source.output = smua.OUTPUT_ON
13. Allow the readings to settle.
14. Get both the multimeter and 2601B-PULSE current readings at the positive full-scale output value. The
two measurements should be made as close as possible in time. Use this command for the
2601B-PULSE:
FS_rdg = smua.measure.i()
15. Turn off the output and disable the pulser:
smua.source.output = smua.OUTPUT_OFF
smua.pulser.enable = 0
