Calibration Count
You can determine the number of times that your function generator
has been calibrated. Your function generator was calibrated before it left
the factory. When you receive your function generator, read the count to
determine its initial value.
•
The calibration count is stored in non-volatile memory, and does not
change when power has been off or after a remote interface reset.
•
The calibration count increments up to a maximum of 32,767 after
which it wraps-around to 0. Since the value increments by one for
each calibration point, a complete calibration will increase the value
by many counts.
