I'm looking into buying my first function generator, and I have no idea what to get.
My needs are very simple, I think. I'm a beginner at electronics repairs, I'm mostly working on vintage synthesizers, guitar amps, drum machines, audio effect units, right now; but I'm interested in learning more about it all and expanding my skills.
What I need out of a function generator at the moment is simply a clean signal that I can then trace around audio circuits to find the source of noise, distortion, etc. I don't yet know why I might later need a 100Mhz signal, or an am/fm modulated signal, or a really strong amplitude.
So a little guidance would be appreciated.
In my shopping so far I've found:
- A used 1987 Dick Smith Function Generator $40cad
10 Hz to 170kHz in three ranges
2 .5 volts peak 10 peak
amplitude stability of .1 dB
Sine, square, and triangle wave forms
- A new KKMoon Chinese AliExpress special $140
Comes in 20Mhz, 60Mhz, and 100Mhz, which one?
Specs here:

Any advice for a signal noob?
