I am putting together a parts list for a test station, and I am currently 
planning the reference clock distribution scheme. What is the minimum power for 
the B210 10 MHz reference clock input? The knowledge base indicates +15 dBm 
maximum, but provides no minimum:

I was planning on distributing a 0 dBm sinusoidal 10 MHz reference clock to all 
the test equipment. Any problems with this approach with a B210?

The data sheet for the PLL that is driven by the REF clock input says -5dBm minimum.   My guess is that if your distributor is able to deliver 0dBm on all ports, it should be fine.
