yes, but for me who doesn't have thousands of dollars to throw at test gear this will do just fine for me because I don't make enough money where I work to go out and blow $500 on a fancy quartz tuned signal generator like the Hewlett-Packards. I barely make enough to be able to afford the essentials and to be able to keep my radio restoration hobby afloat let alone trying to buy test gear. 
I have Autism and other disabilities so I get SSDI which mostly goes towards rent and groceries, and then my paychecks from work have to go towards gas for my car, and getting parts for my radios and buying radios to fix up, and other stuff like that. 

So yeah with that in mind like I said a simple analog signal generator like the ones I bought are more than enough for what I need considering most of the radios I restore are usually AM Only, AM/FM, and AM/SW radios which don't need those fancy Hewlett-Packard Signal Generators because I'll only be going up to about 150 Mhz at the most I won't ever use anything going into the Ghz range.
