The only parameter that can be user calibrated is the DC gain
accuracy. If any of the other parameters, bandwidth, trigger
sensitivity, or time scale accuracy does not meet published
specifications, the unit must be returned to B&K Precision for repair.
The oscilloscope under test must be warmed up for at least 30
minutes prior to the start of any performance test.
