Programming remote control keys
The next step is to program the remote control keys on the 2260
(or 2250) acoustic intensity probe. Notice on the probe handle
that there are two keys or buttons: one on the front of the handle
and one on the back of the handle. The key on the front is KEY
A; the one on the back is KEY B. KEY A and KEY B can be
assigned any function or keystroke of the 2900B RTA. Typically,
one assigns KEY A the task of initiating and terminating a measurement, and KEY B the task of storing a measurement. Let’s go
with this convention.
