H B-trigger delay time and horizontal delay time are independent functions. When
you establish a t ri gger conditi on using either the A t ri gger alone or the A and B
triggers together, you can also use horizontal delay to delay the acquisition by an
additional amount.
H When using t he B trigger, the A t rigger can be any of the followi ng types: Edge,
Glitch, Width, or Timeout. The B trigger type is always Edge type.
More Operating Tips:
