Processing Measured Data
The event handler for TriggerProgress detects when a sweep is
complete and calls
GetAndSaveRawData
to process the data. This
routine transfers the data, forms the appropriate file name,
saves the file, and updates the statistics for the gain and the
group delay. Key to the name of the file is the groupID, which
holds the date string required to make the name unique. If there
are no files in the save directory, groupID will be blank. The
groupID is made progressively more specific – adding date, then
time if needed.
The statistics are accumulated in statistics structures called a
statsBlock. There are two forms of the statistics provided – the
absolute values, and the differential from the first sweep.
Variables that begin with allTrace accumulate the absolute
values, and variables that begin with deltaTrace accumulate the
delta values.
When all the groups have been acquired, the statistics are
written to a summary file.
