Brian, There is no provision to trim the crystal frequency on the XG2. This signal generator is designed to produce a well controlled output level, but not a precise frequency reference. It *is* a frequency stable signal source, but the exact frequency depends on the particular crystal. If you want to move the frequency down a little bit, you could add some small NPO capacitors across the crystal leads. Experiment to determine the value needed. I guess one could install some surface mount trimmer capacitors on the bottom of the board, although the height of the feet might have to be increased to allow enough vertical space for the trimmers.
