Model 2701 User’s Manual Getting Started 1-39

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).
