To solve this problem, the Trig > HoldOff
function specifies a time period during which triggering is inhibited. By
setting the Trig > HoldOff period to be slightly less than the frame
interval, the instrument can be made to ―lock on‖ to the framing pattern
and present a stable display. The minimum HoldOff value is 100 ns, the
minimum interval after a trigger event before the next trigger can
occur. Entering ―0‖ as the HoldOff parameter disables HoldOff.
