I tried
.step param r1 490 10 -10
and
R2 set to {500 - {r1}}
output seems to be all-right...
cheers

Hello,
I'd like to simulate a 500 ohm pot by using a voltage divider: (View

[Ra]

CCW
and stepping Ra from 499 ohms to 1 ohm in one ohm steps while
simultaneously stepping Rb from one ohm to 499 ohms in one ohm steps.
I tried .STEP PARAM {Rx} 1 499 1 for the ascending resistance, and
that works, but for the descending: .STEP PARAM {Rx} 499 1 -1 doesn't
work.
Matter of fact, it gives me the same result as the ascending!
Help, please?
