[time-nuts] Measuring ADEV for a beginner

Usually "phase detectors" (we prefer to call them Time Interval
Analysers) have data interfaces (RS232, GPIB, LAN). If you build your
own then the interface is up to you: usually an RS232 is the best
choice. The software to use: take a look at the Miles' TimeLab
<www.ke5fx.com/timelab/readme.htm> or
<http://www.thegleam.com/ke5fx/>. Of course, in case of the GPIB, you
also will need an adapter: GPIB/USB or GPIB/LAN but the less expensive
GPIB/RS232 maybe a good choice.

What I haven't come across is a simple explanation of the basic setup required to go about collecting the data.  John Miles referenced this page http://www.ke5fx.com/tpll.htm, and the simple setup at the bottom of the page looks like a reasonable place to start.  Seems that I'd need to acquire a phase detector and build or buy some filters and the amp.  I can probably figure that out, but how do I get the data into a PC?  Is there a basic hardware and software setup that someone could point me to or recommend?
