Signal generator question

[Oddvar R]

I am thinking about buying a signal generator to use with my oscilloscope, to be able to trouble shoot tube amps. Is there any advice on what to buy? As cheap as possible?

Phone app and Bluetooth adapter.

Ok, that's a good tip. What bluetooth adapter?

[martin manning]

There are many options. Just google "Bluetooth audio adapter". You'll also need a 1/8" TRS (stereo) to 1/4" TS (mono) plug adapter.

A real signal generator (the cheap imports) costs the same as a Bluetooth module. I use this one, and like it:

The Bluetooth adapter doesn't need to be anything fancy. There are many under $10.

I just use a 3.5mm to 1/4 inch cable.

Thanks guys, I think I'll try both phone and the DDS. Only problem these days is that the mail worldwide is taking an unprecedented long time.
