If anybody's interested, I have a perl script (running under Linux, using the linux-gpib tools) that controls a 59307A and HP 5334A to do long-term logging of four PPS sources against each other. It takes a 100 second average of each PPS source sequentially; I end up with six log files, each with a tau of 600 seconds: CS1-GPS, CS2-GPS, RB1-GPS, CS1-CS2, CS1-RB1, and CS2-RB1. If anyone's interested, I'd be happy to make that program available, though it's not polished up for distribution. The data files from this program are the basis for phase and adev plots at http://www.febo.com/plots/ which are updated hourly. The software that generates those plots is called stable-stats and is available for download at http://www.febo.com/time-freq/tools/. (Unfortunately, at the moment the plots are out of date as we had a power failure last week and I don't have the clocks reset yet; that's a project for this weekend.)
