smuX.cal.date
X = SMU channel (a or b)
Attribute
Calibration date for the active calibration set.
Default
0
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
caldate = smuX.cal.date
-- Reads calibration date.
smuX.cal.date = caldate
-- Writes calibration date.
caldate
Sets the current calibration’s adjustment date.
Remarks
•
smuX.cal.date
must be set to the date the adjustment was done using the UTC time and
date. The date is stored as the number of seconds since UTC 12:00 am Jan 1, 1970.
• This attribute stores the calibration date associated with the active calibration set. The calibration
date can be read at any time but can only be assigned a new value when calibration has been
enabled with the
smuX.cal.unlock
function.
• This attribute is stored with the active calibration set. If a different calibration set is restored, this
attribute will reflect the date stored with that set.
• Due to the internal storage format, smuX.cal.adjustdate is only accurate to within a few minutes
of the value set.

Example
Sets calibration date for SMU A to the current time set on the instrument:
smua.cal.date = os.time()
smuX.cal.due
X = SMU channel (a or b)
Attribute
Calibration due date for the next calibration.
Default
0

Example
Sets calibration due date for one year from the current time set on the instrument:
smua.cal.due = os.time() + 365 * 24 * 60 * 60
