10. Repeat steps 7 to 9 for each adjustment point.
11. Disconnect the function generator. Connect VirtualBench channel 1 to the oscilloscope
calibrator active head, as shown in Figure 25.

12. Call MSO Get Range Calibration Adjustment Points. This will return
two arrays:
• Range—A numerical array specifying the range being calibrated
• Adjustment Point—A numerical array specifying the DC voltage required to perform
the adjustment
13. Use the oscilloscope calibrator to generate a DC voltage with the adjustment point supplied
from the output of MSO Get Range Calibration Adjustment Points.
14. Wait 5 seconds.
