I have a sig gen that uses a single BNC for input/output of the 10 MHz reference. You have to set it for in or out using the interface. However, if the sig gen thinks that the external reference is no longer there, it automatically switches to using the internal reference, and outputing it on the BNC. My question is, will the TADD-1 be harmed if the sig gen is sending 10 MHz into one of the TADD-1 outputs? Joe Gray W5JG

How strong is the signal output? I think that should be a fairly trivial analysis from there on. Compare it to strong reflection on unterminated outputs on the TADD-1. I think you see where I am going with this analysis. Cheers, Magnus
