Trigger Modes

The following figure shows the instrument’s arming/triggering model:

Notes:

(1)

The instrument is always initiated in CONTINUOUS modes.

 

The instrument is automatically initiated in MANual started/gated modes.

Use the :ARM subsystem to select the overall triggering mode of the

 

instrument (CONTINUOUS, STARTED, GATED), and the :TRIGger

 

subsystem to select the pulse period source, triggering and number of

 

pulse periods per :ARM event (BURST length). In pattern mode the

 

pattern length is the sum of each used segment’s length.
