IVISCOPE_VAL_WIDTH_TRIGGER

Configures the oscilloscope for width triggering. A width trigger occurs when the oscilloscope detects a positive or negative pulse with a width between, or optionally outside, the width thresholds. You specify the width thresholds with the IVISCOPE_ATTR_WIDTH_HIGH_THRESHOLD and IVISCOPE_ATTR_WIDTH_LOW_THRESHOLD attributes. You specify whether the oscilloscope triggers on pulse widths that are within or outside the width thresholds with the IVISCOPE_ATTR_WIDTH_CONDITION attribute. You specify the polarity of the pulse with the IVISCOPE_ATTR_WIDTH_POLARITY attribute. The trigger does not actually occur until the edge of a pulse that corresponds to the width thresholds, width condition, and polarity you specify crosses the trigger level that you specify with the IVISCOPE_ATTR_TRIGGER_LEVEL attribute.
