See also "Triggering," starting on page 80 in chapter 3.
The meter's triggering system allows you to generate triggers either
manually or automatically, take multiple readings per trigger, and insert
a delay before each reading. Normally, the meter will take one reading
each time it receives a trigger, but you can specify multiple readings (up
First time SCPI users,
to 50,000) per trigger. You can also set an infinite trigger.
see page 183
Triggering the meter from the remote interface is a multi-step process
that offers triggering flexibility.
The diagram on the next page shows the meter's triggering system.
First, you must configure the meter for the measurement by
selecting the function, range, resolution, etc.
Then, you must specify the source from which the meter will accept
the trigger. The meter will accept a software (bus) trigger from the
remote interface, a hardware trigger from the rear-panel Ext Trig
(external trigger) terminal, or an immediate internal trigger.
Then, you must make sure that the meter is ready to accept a trigger
from the specified trigger source (this is called the wait-for-trigger
state).
