Hi Don,
Yes, I've heard of SRDs. I think every Rb standard uses them. I
recently purchased a YIG Multiplier that includes an SRD followed by a
YIG filter. But, from my reading, there are some significant issues
that you run into when driving an SRD. I'm still playing with mine.

I'm in the same position as you regarding testing at high frequencies.
You might be able to get a signal at the second or third harmonic of
your generator by cranking the level to the maximum and then using the
counter's Band 3 frequency limits feature to only look at that
frequency.

You can also get a step recovery diode and generate a bunch of harmonics...
