Smux.contact.speed - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
Details
If you attempt to perform a contact resistance measurement when any of the following conditions exist, an error
will be generated.
When the output is on and any of the following:
•
SMU is a current source with current range set to less than 1 mA (error code 5065, "I range too low for
contact check")
•
SMU is a voltage source with current limit set to less than 1 mA (error code 5050, "I limit too low for
contact check")
When the output is off and any of the following:
•
The output off mode is High-Z (error code 5048, "Contact check not valid with HIGH-Z OUTPUT off")
•
The output off mode is Normal with the smuX.source.offfunc attribute set to
smuX.OUTPUT_DCVOLTS and the off current limit set to less than 1 mA (error code 5066,
"source.offlimiti too low for contact check")
•
The output off mode is Normal with the smuX.source.offfunc attribute set to
smuX.OUTPUT_DCAMPS and the source range is less than 1 mA (error code 5065, "I range too low for
contact check")
Example
if not smua.contact.check() then
smua.contact.speed = smua.CONTACT_SLOW
rhi, rlo = smua.contact.r()
print(rhi, rlo)
exit()
end

The speed setting. Set to one of the following:
0 or smuX.CONTACT_FAST
1 or smuX.CONTACT_MEDIUM
2 or smuX.CONTACT_SLOW
Source-measure unit (SMU) channel (for example, smua.contact.speed applies
to SMU channel A)
Section 7: TSP command reference
Check contacts against threshold.
Set speed for SMU channel A to slow.
Get resistance readings.
Output contact resistances to the host.
Terminate execution.
