Use zero beat to calibrate sig gen if no freq counter available. To zero beat turn on AM radio to station of known freq. Turn on sig gen and set to freq of radio. Place sig gen output near radio antenna to radiate signal to radio. Sound from speaker will probably be altered. Vary sig gen freq to cancel sound from speaker. The sig gen setting when sound is at minium corresponds to the station freq. Make a plot of sig gen indicated freq vs actual freq and you have a calibration curve for your sig gen. Heathkit sig gen manuals describe zero beat in detail. Its easier using freq counter. Other members please elaborate or correct my explanation.
