I've been trying to design a double balanced Gilbert Mixer and following the one of the this tutorial online to set up my test bench. I do the PSS analysis with PAC without a problem. But when I try to plot the conversion gain vs LO power, and try to go Results tabs in ADE L to select the Direct Plot option, I can't find it the "main form". I've tried it with my other schematics, OPAMP, TIA etc. but the "main form" never shows up under the Results >Direct plot tab. Anybody have any ideas what may be going wrong?
