Thanks to everyone who provided input, I thought it might be a worthwhile topic. The Fluke 6060B I have specs the Reference input at 50 Ohm and accepts several frequencies, a nice feature. The HP 5334B has a 1k Ohm input impedance shunted by <20 pf it wouldn't hurt to terminate this input, and will as soon as I find or build a termination. Any other equipment I get that is frequency reference dependent must have an external reference input or I won't bother with it.
