Just aquired a signal generator Model # HP8656A. does any one know if it can be used to align ssb using 2 tone? thanks.

NO. It is an RF generator. You need an AUDIO generator to generate a two-tone test. The two tone MUST be equal in amplitude and not harmonically related. 1KHz and 1.7 KHz are commonly used.
Use your smartphone as the AF generator;

The best way to do that is with test equipment that is designed for it. Like the B&K test centers, and they need to be calibrated too.
They have the dual tone function built in as far as the 500 mv you need a scope to read that and need to know what point to look at.
You also need to know is that 500 mv rms or peak to peak.

Without a true, powered PEP watt meter, looking for exact accuracy in the modulation mv is a bit of a waste of time. Just set the ALC so that most of your word peaks on SSB stay within the 12 watt PEP level and call it a day. Precision is more important with things like the bias.
A signal generator is an electronic device that produces different frequencies and waveforms, word generator commonly used for testing and troubleshooting circuits. It helps engineers and students analyze system behavior by providing accurate and controlled signals during experiments or diagnostics.
Your a bit late to the party! Previous post to this one was six years ago and OP hasn't been here since last June..........
