Is there a way to change the values of port impedances in Momentum post-processing visualization?
Along with the 'Set Port Solution Weights...' it would be very useful to be able to adjust the port impedances. Â Many circuits including interstages of amplifiers have source/load impedances in the 1 to 2 ohm range. Â The actual current distribution can be very different than the one for 50ohm ports.
Obviously, the ports can be edited before the Momentum simulation but is there a way to see the effect of changing port impedances withouth re-running the EM-simulation?
The ability to view the current distribution with different termination (and weights) is a feature available in other EM simulators.

What do you mean by transferring the currents to the postprocessor manually ?
Because if it doesn't, just setting the weights according to the currents probed in the AC simulation is not enough.
For example think of a 2-port which includes a line with a resistor to ground in parallel with port 2. The way the current splits between the resistor and port 2 depends on the ratio between the resistor and the impedance of port 2.
Can we discuss this on the phone. It may be easier to explain. 978.684.5435
I tried sending you a message but this is what came back:

Thank you Agilent Technologies for attending to my question.
