original "CAL" knob. But I have been wrong before.
Mine also reads “VAR”...

This all beggars the question of why a "Frequency Vernier" is needed when
there is a big "Frequency Hz" control on all of these Function Generators?

Perhaps it just adjusts the frequency over a small range?
Probably. I’m no expert, but I don’t really see any practical use for that feature.
