The following figure shows the instruments arming/triggering model:
For details of the
trigger count
command, refer to
“:TRIG:COUN” on
page 89.
You program the comprehensive triggering capabilities of the instrument
using the SCPI :ARM and :TRIGger subsystems. Using these two
command subsystems you can program the operating modes of the
instrument which are set up using the M
ODE
/T
RG
screen on the
frontpanel.
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 segments length.

Notes:
(1) The instrument is always initiated in CONTINUOUS modes.
The instrument is automatically initiated in MANual started/gated modes.
