I want to inject a current source with a frequency as an AC current when simulating EMI near/far field. I would like to know what procedure I should use to inject the AC current. 

I see the frequency dependent checkbox in the figure below, but I can't figure out how to apply it.

I am using Ansys SIwave2023 R1. 
What I want to simulate is Near/Far Field Simulation with a current of 6A at 24MHz.

Hello,

 

In the screenshot you provided, you may put desired current of 6 amps as the magnitude  and then proceed to set-up frequency sweep in Near/Far field set-up (in the “Compute Near/Far field” pop-window” which is shown on slide 9 in the attached file. Here you will define frequency points of interest by defining your frequency sweep (or single points by adding another row to frequency range). Please see the screenshots below

 

This method show you the fixed 6 amp current at frequencies defined in the set-up, but if you are interested in having current dependent on frequency, then that’s when you will need to change from “Frequency Independent” to “Frequency Dependent” within your Set Current Source Properties window you are showing. In this case, you will need to define a .txt file that include data in .
