Default Re: Test equipment for valve radio repair

A simple function generator usually generates a choice of sine, square or triangular waves. The sine waves are often a bit distorted at the peaks. Sophisticated function generators (often called arbitrary function generators) can be programmed to generate any waveform. Most FGs only go up to 1MHz or so. They often go down to fractions of a Hz. Frequency can often be swept over a wide range so they can work as a wobbulator if they go to high enough frequencies.

Signal generators produce sine waves. Sometime also squre waves at lower frequencies. They usually have facilities for amplitude modulation, sometimes FM too.
