Model 2601B-PULSE System SourceMeter Instrument Reference Manual Section 13: Calibration
2601B-PULSE-901-01A April 2020 13-39
The two measurements should be made as close as possible in time. Use this command for the
2601B-PULSE:
FS_rdg = smua.measure.i()
26. Turn off the output and disable the pulser:
smua.source.output = smua.OUTPUT_OFF
smua.pulser.enable = 0
27. Send the source calibration command using the -range, -zero and -FS multimeter readings, and -zero
and -FS source values for the parameters:
smua.source.calibratebiasi(-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 250 mA range:
smua.source.calibratebiasi(-250e-3, -2.5e-3, -2.4e-3, -225e-3, -223e-3)
Step 6. Pulse adjustment
This procedure adjusts the pulse source and current and voltage measurements.
If you do not need to adjust all three, only send the command for the area you want to adjust:
• Pulse source: smua.pulser.source.calibratei()
• Pulse current measure: smua.pulser.measure.calibratei()
• Pulse voltage measure: smua.pulser.measure.calibratev()
For detail on wiring the pulse load, refer to Pulse loads (on page 13-3).
