The FTS 1050A  sounds like a very nice toy. I agree with one of the
other suggestions - use the device as a reference for a DDS generator,
so you can have any frequency you like, with high stability.

Many of the newer DDS chips have excellent performance, and in addition
include a clock multiplier. I have an AD9852 kit, and it can multiply by
up to 20, so would give ~120MHz as the reference from your FTS1050A, and
then have useful output to 30MHz. The synthesizer is 48 bit, so the
steps are very small.

I use mine with an odd-frequency FEI Rubidium source (about 60MHz) and
the results are very good - any frequency I want with microHz
resolution.
