Selecting the Operation Mode
There are two operation modes available:
³
Manual mode is available only when you work with a switch. It is used
to acquire traces one at a time. Before each acquisition, you must
select the desired channel from the list of channels you had previously
configured.
³
Auto mode is available with or without a switch to perform a sequence
of acquisitions:
³
Once
³
Indefinitely (until you stop the test manually)
³
A specified number of times, at certain intervals
If you choose to repeat the sequence, you must specify a time gap
to set the interval for repeating the sequence. If the time gap is
shorter than the time required to complete a sequence, there will
be no pause between repetitions.
