I had a problem using a voltage divider to input a voltage (between 0 and 12 volts) to a low impedance signal line. I used a potentiometer as the voltage divider, and as I turned the pot the signal voltage would suddenly jump from around 1 volt to over 10 volts. So that did not work. My new plan is…

Problem using a voltage divider to input a voltage to a low impedance line

how "low" impedance? 500? 50 ? 1 Ohm? how "fast" voltage has to be set?
