4. Call MSO Configure Analog Channel with the following parameters:
• Enable Channel =
TRUE
• Channel = mso/1
• Vertical Coupling = DC
• Probe Attenuation = 1x
• Vertical Range = 20
• Vertical Offset = 0
5. Call MSO Run.
6. Call
MSO Read. Calculate and record the average analog waveform. Verify that this
measurement falls within the limits in Table 13.
7. Call MSO Stop.
8. Repeat steps 4 to 7 for all of the ranges in Table 13.
Note The 0.02 V range only applies to the VB-8034 and VB-8054.
9. Call MSO Close.
