k. Send the source calibration command using the range, +zero and +FS
multimeter readings, and +zero and +FS source values for the
parameters:
smua.source.calibratev(range,src_Z,DMM_Z_rdg,
src_FS,DMM_FS_rdg)
Where:
range
= present calibration range
src_Z
= +zero 2600 source output value
DMM_Z_rdg
= +zero DMM measurement
src_FS
= +FS 2600 source output value
DMM_FS_rdg
= +FS DMM measurement
Typical values for the Model 2601/2602 1V range:
smua.source.calibratev(1,1e-10,1e-5,0.9,0.903)
Typical values for the Model 2611/2612 2V range:
smua.source.calibratev(2,1e-10,1e-5,1.8,1.802)
l. If this step is not on the CALA sense mode, send the measure
calibration command using the multimeter and Series 2600 readings,
and range setting for the parameters:
smua.measure.calibratev(range,Z_rdg,DMM_Z_rdg,
FS_rdg,DMM_FS_rdg)
Where:
range
= present calibration range
Z_rdg
= +zero 2600 measurement
DMM_Z_rdg
= +zero DMM measurement
FS_rdg
= +FS 2600 measurement
DMM_FS_rdg
= +FS DMM measurement
Typical Model 2601/2602 1V range values:
smua.measure.calibratev(1,1e-4,1e-5,0.92,0.903)
Typical Model 2611/2612 2V range values:
smua.measure.calibratev(2,1e-4,1e-5,1.82,1.802)
m. Select negative polarity, then set the source output to the negative zero
value, for example:
smua.cal.polarity = smua.CAL_NEGATIVE
smua.source.levelv = -1e-10
n. Turn on the output:
smua.source.output = smua.OUTPUT_ON
o. Allow the readings to settle, then get both the multimeter and Series
2600 voltage readings at the negative zero value. (The Series 2600
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 Series 2600:
Z_rdg = smua.measure.v()
p. Turn off the output:
smua.source.output = smua.OUTPUT_OFF
