Frequency pair

I'm guessing It means one implies the other,

analogue TV would be an example. a picture carrier at a certain frequency implies a sound carrier at a fixed offset (which varies internationally) from that frequency.

If I'm right Ther'll be a table somewhere that lists VOR and DME freqencies.

Exactly right. What in means in this case is that once the NAV radio is tuned to the VOR, it's also tuned to the proper frequency (in what is basically a separate receiver) to access the DME (Distance Measuring Equipment) system associated with that VOR. Having the VOR/DME in a set, standardized relationship permits these receivers to be designed to do this without operator intervention.
