Smux.contact.speed - Keithley 2606B System SourceMeter Reference Manual

2606B System SourceMeter® Instrument Reference Manual
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

Details
This setting controls the aperture of measurements made for contact check. It does not affect the
smuX.measure.nplc aperture setting.
The speed setting can have a dramatic effect on the accuracy of the measurement (see
specifications).
