In the following example, SYN is specified for the trigger arm, trigger, and sample
events. Five readings per trigger are specified. A single occurrence of the SYN
event (line 60) satisfies the trigger arm, trigger, and the first sample event and
initiates the first reading. Four more SYN events (one for each reading) are then
required to initiate the remaining four readings.

TIMER
The following program makes 4 readings in response to the synchronous trigger
(line 60). The first reading is made immediately after the preprogrammed default
delay; the remaining 3 have a 200 ms interval between them.
