Delay Button
Push the DELAY button when you want to delay the acquisition
relative to the trigger event. Turn the horizontal POSITION control
counterclockwise to incre ase the delay; the trigger point moves to
the left and ultimately outside of the acquired waveform. Then, you
can adjust the horizontal SCALE to acquire more detail a round the
area of interest (center of the screen).
When delay is on, the trigger point separates from the horizontal
expansion point. The horizontal expansion point stays at the center
of the screen. The trigger point can move off the screen; when this
happens, the t rigger marker turns to point in the dire ct ion of the
trigger point .

Use the delay feature when you want to acquire waveform detai l that
is separated from the trigger event by a significant interval of time.
For example, you can trigger on a sync pulse that occ urs once every
10 ms and then look at high-spee d signal cha racteristics that occur
6 ms after the sync pulse.
