Hi,
I am working on function gen project (sin/sqr/tri) and I have used potentiometer to adjust frequency. At some point i am thinking to replace it with rotary encoder and modifying codes in micro-controller.
I went on googling and learned the types of rotary encorders.
I found this basic encoders.

and these optical or quardrature encoders
https://www.sparkfun.com/products/11102 (https://www.sparkfun.com/products/11102)
My question is: what kind of encoders do they use in those big rigol or agilent function generators (or signal generators ) ?(just curious)
If someone could paste some link of those i would love to see them. As I do not know what to google on those.
thankyou

Pretty much the same as your first "basic" encoder. Only higher quality (usually) on high-end gear.
This Bourn series was used in some Lecroy scopes for instance: https://www.bourns.com/products/encoders/contacting-encoders/product/ECW (https://www.bourns.com/products/encoders/contacting-encoders/product/ECW)
