Sadly not all Agilent/HP equipment uses rotary encoders like this. One of their function generators was brought to me with a clear rotary encoder fault. I opened it up expecting to find a rotary encoder like this. But instead found they had implemented it using circular tracks on the PCB and the knob turned a metal wiper which shorted out the tracks as it turned. After a couple of years of use the tracks start to develop grooves and wear out. There isn't much you can do without replacing the entire front panel which wasn't economic to do. I think within 5 years we binned 15+ of those units.
Old HP/Agilent equipment was beautifully made but in the few years before the sale to Keysight quality took a real dive. |

Keysight was actually formed by spinning-off Agilent's electronics test-and-measurement businesses (leaving behind really I think just the life-sciences stuff?) so there was no sale per se.
