User-definable Measurement Thresholds The oscilloscope allows you to set your
own thresholds for automatic measurements.
You can set both the upper and lower
thresholds from —25% to 125%, as long as the upper threshold value is always greater
than or equal to the lower threshold. The middle threshold is always equal to the
midvalue between the upper and lower threshold.
