.4 Using the Signals
(1) With measurement in the hold state
In the hold state, measurement starts when TRIG
――――――
becomes L, then EOC
becomes 1 when measurement ends. EOC then remains 1 until the next time
TRIG
――――――
becomes L.
･ During measurement, EOC is also invalidated when the next TRIG
――――――
signal is
input.
(2) With free-running measurement
With free-running measurement, the 3227 measures repeatedly at the internal
sampling rate, with EOC becoming 1 each time measurement ends.
