Specifying Pretrigger Depth
ATS850 acquires a certain number of samples, called the
pretrigger depth,
before it allows the trigger circuitry to
operate, thereby guaranteeing that the required number of
sample points will be captured before trigger occurs.
User is allowed to set pretrigger depth for an acquisition
session. Same values are used for all records captured in
that session.
Pretrigger depth can be a minimum of 0 points and can be
specified with a 4 sample resolution up to a maximum of
(Record Length –64).
Specifying Record Count
User can specify the number of records that must be
captured in one acquisition session. The minimum value
must be 1 and the maximum value is given by:
Max. Records = (Per-Channel Memory) / (Record 4)
