Whilst not cheap, that is an interesting little device. The fact it
can work to 4.4 GHz, does in fact mean it would be possible to extend
the VNA up to 24.4 GHz at the high end, which would be potentially
useful as it covers the 12 mm. Not my immediate priority, but the fact
there are two osciallators, and they cover a wide range, does make it
