Original Question: Bode plot in SimPE by AngelaHwang
Would you please help me to get phase/gain plots of attached schematics?
I placed Bode plot probe on my schematics however I couldn't get the result. would you please help?
Thanks in advance!

Is this the plot you want to achieve?

Please see attached. I made some variations on your original schematic.

Is there anyone who has a ownership on this question?
Yes, have you got from my attached schematics? I could see some example schematics however not easy for me to get it from new schematics.. could you please share each step if you don't mind?
E1 will convert the differential inputs into single-ended output. Since based on the schematic, you are building a Difference Amplifier which translate to the function Vo = (Vp - Vn) (Rf/Rg). The E1 output is the Vp-Vn, and by then you will get the closed-loop gain and phase using the bode plot probe, which compares the magnitude of the output relative to the differential input.
Appreciate on your prompt reply any attachment too.
By the way, could you explain what is the purpose of Amplifier, E1 in your modified drawing? Also, what are the main requirement to see phase and gain plot in SimPE? I couldn't find common key parameters as compared from example schematics and yours.
