I have left some inline comments of varying importance.

I have one question about the step sizes: if I set the step size to, say, 0.5 V, what then happens if I set aim.volt(aim.volt() + 0.1)? I suspect that the setter for volt will have to handle this.

Yes, driver correctly handles this situation.

@GateBuilder would you mind revealing in some more detail what happens in the following case:
if I set the step size to, say, 0.5 V, what then happens if I set aim.volt(aim.volt() + 0.1) ?

Assume your current voltage is 0.5V. If you call aim.volt(aim.volt() + 0.1), then, if you get the voltage, your new value is 0.6V (which is what I have done with the actual instrument). In short, step size does not matter unless it is explicitly used.

@GateBuilder sweet! Thanks for explaining.
