Recommend me a signal generator

[Harry Klippton]

For several years, I've been using the Keuwlsoft function generator on an old phone that has a headphone jack, but now I have a need for a 400hz -10dBv signal for calibration purposes. Based on what I measured, I can't quite get -10dBv out of the phone, and it's not a calibrated signal.

This is something I have a regular need for, not a one-off. If there's something cheap that'll do the job appropriately, I'm all for it. But I don't need to cheap out just to be cheap. "It's just for DIY" doesn't apply cuz it's not.

I've never used an actual signal generator before, so I don't know what I don't know or what to look for exactly.

I have an Siglent SDG1032X. I wouldn't call it cheap, but it's far from the most expensive either.

It might be overkill, or maybe not. It'll definitely do what you need.
