That's an easy one. Either an HP3325B or a Tektronics FG-5010 will do exactly what you need. The upper frequency cutoff on these generators is around 20MHz, and that renders them useless to me for filter designs into the VHF and UHF spectrum. I own a '5010 and it's a neat piece of gear for what it is.

Thus, my search for an instrument which outputs a stable signal to 1GHz or beyond.
