I'm learning, thanks. So in the test plan I'm writing, I state that the DME test frequency I used was the VOR or ILS frequency I tuned, and some super smart avionics person could work out the pairing if they needed to?
And, I could tune the VOR or ILS frequency, get the DME going, and then select DME "hold" and it stays on that frequency, when I reselect that VOR/ILS?
I think this is all coming back to me from my copilot days in the Cheyenne of 30 years ago! (I honestly have not used DME since!)
