#114345 - These don't serve to simplify anything Responding to: ???'s previous message |
Yes, that's how lots of modern equipment is done. However, it doesn't serve to simplify anything in the process. One additional thing about digital interfaces of this sort is that it's not going to produce that sense of infinite adjustability that one accustomed, as I am, to the "old" look and feel. Just as it's frustrating to work around the limitations of synthesized frequency generators that can get within 0.1% of the desired frequency but can't hit it exactly, it's frustrating to try to set 7.21 volts when the instrument doesn't have that as a valid setting. With analog controls, you can, ultimately, reach "just-right" if you're patient.
