Balanced low frequency signal transmission with shielded cables is
easier with XLR connectors, provided one uses 1 connector per channel.
Enrico's paper on the use of counters to measure frequency stability
Shows why the SR620 is preferable to the Agilent 53332A/53331A and the
Pendulum counters for this application.
Using the HP5370A/B or other time interval counters in the picket fence
mode is also OK.
The cost of the SR620 highlights the need for a relatively inexpensive
reasonably high resolution timer counter or time stamp device for such
