2600S-901-01 Rev. A / May 2006
Remarks
• This function generates and activates new calibration constants for the given range.
The positive and negative polarities of the instrument must be calibrated separately.
Use a positive value for
range
to calibrate the positive polarity and a negative value
for
range
to calibrate the negative polarity.
• Typically the two calibration points used will be near zero for calibration point 1 and
90% of full scale 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.unlock
is made.

smuX.measure.count
X = SMU channel (a or b)
Attribute
Number of measurements performed when a measurement is requested.
Usage
count = smuX.measure.count
-- Reads measure count.
smuX.measure.count = count
-- Writes measure count.
count
Number of measurements.
Remarks
• This attribute controls the number of measurements taken any time a measurement
is requested. When using a reading buffer with a measure command, the
count
also controls the number of readings to be stored.
• The
reset
function sets the measure count to 1.

Example
Sets measure count for SMU A:
smua.measure.count = 10
