You can import it the same way, actually -- install the TimeLab beta at
www.ke5fx.com/timelab/setup.exe and use File->Import ASCII Phase Data to
read your file. Set Nominal Frequency to 1, Numeric Field # to whichever
field contains your time data (2 for capture.txt), and the 'x' field to
250E-12 to convert to seconds. That should give you the same graph I
Ulrich Bangert's Plotter application is also good for this sort of thing,
although I don't immediately see how to make it scale the data by 250E-12 to
convert it to seconds.

Once lower measurement floors are desired and the system grows in complexity
and cost, other approaches besides TICs start to look more appealing. For
what it does, though, this is a really nice little board.
