15. Call MSO Adjust Range Calibration with the following parameters:
• Channel—
mso/1
• Range—Supplied from the output of MSO Get Range Calibration Adjustment Points
• Adjustment Point—Supplied from the output of MSO Get Range Calibration
Adjustment Points
16. Repeat steps 13 to 15 for each adjustment point.
17. Call
MSO Get Offset DAC 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
18. Use the oscilloscope calibrator to generate a DC voltage with the adjustment point supplied
from the output of MSO Get Offset DAC Calibration Adjustment Points.
19. Wait 5 seconds.
20. Call
MSO Adjust Offset DAC Calibration with the following parameters:
• Channel—mso/1
• Range—A numerical array specifying the range being calibrated
• Adjustment Point—A numerical array specifying the DC voltage required to perform
the adjustment
21. Repeat steps 18 to 20 for each adjustment point.
22. Remove the connections from channel 1.
23.
(VB-8012) Connect a 50 Ω BNC terminator to oscilloscope channel 2, as shown in
Figure 26.
