Hi,
The price for the signal generator you linked, $54 is really good. I'm tempted to order one as a second signal generator (with two I don't have to worry about what leakage there might be between the channels). Even if imperfect compared to expensive signal generators they are sure handy and useful. I like the similar one I have. Just don't expect to calibrate your atomic clocks with it.?
I recently, by accident, drove the full 20 volt output into a short circuit and the signal generator seems to have survived with nary a puff of smoke emanating from the spaces around the buttons, while running a test to find the resonant frequency of a cheap piezoelectric transducer. Works well for many tasks at a very economical price.?
Here is a link to a discussion about these inexpensive signal generators. Check the comments before and after this message, too.
