Ed.... DNB Engineering in Fullerton has run CS114 for me on serveral products while I observed the testing. I do not understand the purpose of the "Loop circuit impedance characterization" procedure, and neither to they. This data is not used in the conduct of the test. I have not been able to find anyone including a PhD who understands why the procedure has these "Loop circuit impedance characterization" steps. What do you do with this data after collecting it? No where in the test conduct steps 4(3) on page 65 of MIL-STD-462D, are any instructions for using this data. Is there someone out there who knows? Also, what "loop circuit" is the mil std referring to?

I need some help unravelling the calculations associated with the MIL-STD-462D Method CS114 Loop Circuit Impedance Test. Specifically, once you have a table of Forward Applied RF Power (in dBm) and Observed Injected Current (in dBuA), how do you arrive at the Normalized Amps per Watt? And what is an "Amp per Watt"? Is that a "mho", a unit of conductance? Or is it a unit of admittance, a Siemen? Anybody out there ever really done this science project?
