list. The following options are available:

• Sweep Mode - Select the trigger sweep value from the Sweep Mode
drop-down list. The following options are available:
•
Auto - When a trigger event does not occur in a certain time, the
instrument automatically forces a trigger, which causes the
instrument to sweep.
•
Triggered - When a trigger event occurs, instrument will sweep.
• Holdoff Type - Select an option from the Holdoff Type drop-down list.
The following options are available:
•
Normal - Once the hold off time is elapsed, the M8131A waits for a
trigger and then it triggers only after the trigger is received.
•
Above - Ignore triggers until the signal is above the threshold value
(for negative slope) for hold off time. Once the hold off time is
elapsed, the M8131A triggers the signal.
•
Below - Ignore triggers until the signal is below the threshold value
(for positive slope) for hold off time. Once the hold off time is
elapsed, the M8131A triggers the signal.
