To set holdoff
You can change the holdoff time to help stabilize triggering.
See Trigger Modes and Trigger Holdoff beginning on
page 3--74 for a description of trigger holdoff. To set holdoff,
do the following steps:
1. Push the ADVANCED button, and select the Mode tab.
2. Select Auto, Time, or Random:
H The Auto holdoff is random when A only, Edge
triggering is selected; otherwise, the holdoff varies
with the horizontal scale and i s equal to 5 divisi ons
times the current time/division setting. Auto
maintains a good value for general purpose
triggering.
H Time lets you enter a holdoff that may allow more
stable triggering than the Auto holdoff. This time is
used at all horizontal scale settings.
H Random selects a new random holdoff time for
each acquisition cycle.
3. To change the holdoff time when Time is selected,
select Trig Holdoff, and enter a value in time using the
multipurpose knob or the keypad.
You can set holdoff from 250 ns (minimum holdoff
available) to 12 s (maximum available).
