smuX.contact.calibratehi
X = SMU channel (a or b)
Function
Calibrate the high/sense high contact check measurement.
Usage
smuX.contact.calibratehi(cp1measured, cp1reference,
cp2measured, cp2reference)
cp1measured
-- the value measured by this SMU for calibration point 1.
cp1reference
-- the reference measurement for calibration point 1 as measured
externally.
cp2measured
-- the value measured by this SMU for calibration point 2.
cp2reference
-- the reference measurement for calibration point 2 as measured
externally.
Remarks
• Contact check measurement calibration does not require range information.
• Typically the two calibration points used will be near 0
Ω
for calibration point 1 and
50
Ω
for calibration point 2.
• All four measurements (
cp1measured
,
cp1reference
,
cp2measured
, and
cp2reference
) must be made with the active calibration set. Corruption of the
calibration constants may result if this is not heeded.
• The new calibration constants will be activated immediately but they will not be
written to non-volatile storage. Use
smuX.cal.save
to commit the new constants
to nonvolatile storage. The active calibration constants will stay in effect until the
instrument is power cycled or a calibration set is loaded from non-volatile storage
with the
smuX.cal.restore
function.
• This function will be disabled until a successful call to
smuX.cal.unloc
k is made.

(calibration).

smuX.contact.check
X = SMU channel (a or b)
Function
Determine if contact resistance is lower than threshold.
Usage
flag = smuX.contact.check()
-- check contact resistance against threshold
Remarks
Attempting to perform a contact check measurement when any of the following
conditions exists will generate an error:
• SMU is configured as a current source with the output on.
• Output is off in High-Z mode.
• Current limit set to less than 1mA.
Details
