Heathkit SG-8 Signal Generator

Good question. That points out a bit of a problem normally. The output of a typical RF generator is very small. It only takes something like 10 uV ( 10 one millionth of a volt) of signal at the radio antenna for the radio to receive it. The problem is many frequency counters need something like at least 100 mV for them to work. One thing to do is turn the generator output up to max to read the frequency and then turn the output down before connecting to the radio. Another thing that sometimes works is to modify the generator and bring out the signal before it goes into the output attenuator to a separate connector. The B&K 2005A has this already done. It has the normal output connector that the amplitude can be varied and a frequency monitoring output connector. Some people have bought small frequency counter modules and install them in the generator if there is room. I don't think the modules have a very precise timebase oscillator in them however.
