20 years ago I would have said the 555 timer was the way to go.  "Limited" settings could be overcome by having different ranges, with a number of different capacitors on a switch or two and a couple of potentiometers.

These days, however, you can wrangle and Arduino Nano clone for the price of a cup of coffee - and you'll be able to program all the variations you could want for servo testing.

I saw a HP33120A 100 uHz - 15 MHz function generator for sale in the UK for £300 which might do the trick for what you want.
