The digital offset can be used to change the offset of each channel. You can program the digital offset of each channel independently using the Digital Offset attribute. The offset can range from –(Vertical Range × 0.4) to +(Vertical Range × 0.4) The digital offset circuit can overflow if the following condition is not met:

–(Vertical Range/2) ≤ Channel Data + Digital Offset ≤ +Vertical Range/2.

If an overflow occurs, the data is clipped and NI-SCOPE returns an error. To prevent data clipping, attenuate the waveform data or reduce the digital offset.

Tip  To change the default error reporting caused by OSP overflows, change the Overflow Error Reporting attribute.
