I have been a strong advocate for the 53131/2 counter since I first
encountered in in 1993. Most of my applications are for a time-interval
counter (TIC) measuring the time interval between an atomic clock and
GPS (see my Timing for VLBI papers at [1]http://gpstime.com). The two
reasons are
1. It is simple and cheap and reliable, especially for the casual
user.
2. It has a simple RS-232 "printer" interface that is really easy to
use. Rick Hambly used the 53131/2 simple interface to make his
Tac32Plus (and Multi) software packages into an integrated TIC
logging utility (see
[2]http://[3]cnssys.com/cnsclock/Tac32PlusSoftware.html)
If you are shopping for a counter, try to find a 53132. It has an extra
digit at the 100 psec level that is quite useful. They appear on Ebay
quite often. My last purchase was a 132 at the $1k level.
73, Tom
