CALibration[:ALL]?
assuming the mainframe is in these conditions: no VXI modules installed in
mainframe, mainframe at a steady state temperature in a constant temperature
environment (fan switch set to FULL for at least ten minutes). This means that this
command should always be issued through the Enhanced Monitor's RS-232
interface. Calibrations performed are:
•
Calculate A/D offset and gain for each VXI power supply. Externally
measured voltages previously reported to the enhanced monitor through
CAL:VAL:VOLT are used for these calculations.
•
Calculated A/D offset and gain for each temperature sensor. Externally
measured temperatures previously reported to the enhanced monitor through
CAL:VAL:TEMP are used for these calculations. Flag any sensor varying
more than ±2 degree off expected.
