Inexpensive modern handheld but pretty good digital frequency counters are available at very low cost. and venerable old ones also pretty cheap pretty much. Have an old model I use to true up my ancient Eico signal generator when aligning old radio sets. Dunno about reliability on really higher harmonics. Anyway, nice to know if generator is putting out a peak prety much on the frequency you read on the schematic to perform alignment. Beyond that, a good analog meter is a best friend for output for a modulated signal, sadly, much better than my ears.
