The Meter takes measurements when triggered to do so. There are five trigger types,
which are described in Table 4-3. Triggers fall into two basic categories:
A measurement can be externally triggered as follows:
For use of the *TRG command, see “Common Commands.”
To enable external triggering from the front panel, perform the following procedure:
