Trigger and return readings — remote programming
There are several commands used to trigger and return readings. The proper commands
and sequence to use depend on the trigger state (continuous or non-continuous) and what
you are trying to accomplish.
Presented here are three fundamental command sequences that can be used to “trigger and
return readings.” These three command sequences (exercises) will accommodate most
basic measurement scenarios. Simply use the command sequence (exercise) that satisfies
your needs:
• Exercise 4 — Trigger and return a single reading
• Exercise 5 — Trigger and return multiple readings
• Exercise 6 — Return a single reading (continuous triggering)
Details on the commands to trigger and return readings are provided in other sections of
this manual. For details, refer to the following sections:
Section 3 — See “Trigger and retrieve readings” in Table 3-7 .
Section 7 — For scanning, see “Trigger commands” in Table 7-1 .
Section 8 — Explains the triggering process.
Section 13 — Covers Signal Oriented Measurement Commands (i.e., FETCh?, READ?).
Section 15 — See Table 15-9 (Trigger command summary).
Appendix D — Shows how trigger and read commands control data flow within the
instrument.
NOTE Each exercise indicates the commands used to configure triggering (“Trigger
configuration”). Once triggering is configured, the commands to trigger and/or
return readings can be repeated as often as desired (unless noted otherwise).
