I have read many pages on using pxf to measure supply noise, and I know to divide the output by the slope of the crossing point get the jitter transfer function
My question is, if the output of a pxf simulation is a voltage-to-voltage transfer function, does it even matter what XF magnitude of the voltage supply source is chosen in the simulation?
In the end, it seems that once the second/voltage transfer function is calculated, you just multiply by the expected amplitude on the supply noise, and it doesn't matter what was chosen as XF magnitude
