I will again when testing the new build, but yes, 5V per div on the scope shows clean flat +-15 and +5. The new one shown here is almost ready for testing anyway.

The new build of the SPGN programable ramp generator is working the way it's supposed to. Glad to have those signals back, and be able to move forward with some new experiments.

The reset signal & direction & spiral/diamond signals go to a true compliment driver (CD4041) and the non inverted & Inverted outputs drive analog switches (IH5012)Originally Posted by mixedgas
