Triggering

First-time SCPI users, see page 198.
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 to 50,000) per trigger. You can also set
an infinite trigger.
Triggering the meter from the remote interface is a multi-step process that offers
triggering flexibility.
– 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).
The diagram on the next page shows the meter’s triggering system.
