% New acquired trace. Should be passed by value in order to prevent
% race condition when multiple NewData events are triggered by
% the same instrument in a short period of time. Passing by value
% makes sure that the trace is not modified before it is received
% by Daq.
Trace
% If false then MyCollector does not acquire new measurement
% headers for this trace. Setting new_header = false allows
% transferring an existing trace to Daq by triggering NewData.

% If the new data should be automatically saved by Daq.
save = false
% If 'save' is true and 'filename_ending' is not empty, Daq appends
% the ending to the file name before saving. In this way the
% default way of generating unique file names by Daq can be
% overwritten.
