Pith, time to post a nice picture of the front of your sig gen or at worse a manufacture and model number. Most have the ability to add a "tone" to the frequency you select on the generator. The generator is like a little radio station in which you can select the frequency you wish to "transmit" on. If you don't have a tone on it, you will not be able to hear it at your speaker or measure it on your meter. It is usually around 400 cycles (annoying). This is often referred to as internal modulation.
As I recall the one you bought had an external modulation feature but that is of little use and requires you to apply a "tone" from another source. I'm hoping it also has an internal "tone" source function.
Picture please.
