API_SCOPE_START_CONTINUOUS
On APX/ACX cards, the Milscope will
continuously copy its 3KB buffers into the
data queue until the data queue is completely
filled. 96KB of data will be returned.
On APE cards, scope will record data until it
is explicitly stopped, or no more buffers are
provided.
2
API_SCOPE_START_SINGLE
On APX/ACX cards, the Milscope will fill both
of its 3KB buffers and 6KB of data will be
returned.
On APE cards, the scope will record data until
all buffers, that were provided before scope
start, are full.
Notes for APX/ACX cards:
Because of technical reasons in continuously mode the returned data size will be 3KB less
than the above mentioned theoretical size.
The Milscope should always be started with the continuously capture mode. In some cases
the capture mode will be forced to single capture mode internaly because of performance
issues. These cases are 50MHz on channel A and B

All API functions return API_OK if no error occurred. If the return value is not
equal to API_OK the function ApiGetErrorDescription can be used to obtain an
error description.
