Post by thread:[EE]:PSPICE

Hello all, I am attempting to simulate an OPAMP oscillator in PSPICE with a dual gang variable resistor. While I can use Transient analysis to see the steady state frequency generated, how can I present a variation on the variable resistor and see the frequency change? Do I have to select a range and simulate a transient response for each point? Or is there a way to do this on the fly?

Your best bet may be to relate the R_var attribute "SET" setting to a global parameter. (e.g.SET = {setting *1} where "setting" is defined as a global parameter). Then you can simulate for a number of different values in the global parameter. It may depend somewhat on the actual model you are using for the pot. - and also the version of Pspice you are using. By using a global parameter it also makes it easy to change the dual gang pot segments simultaneously.
