Inquiry Regarding Raw Data of S-Parameters and Calculation of EMI SE
I am writing to discuss some aspects of the raw data we've acquired concerning S-parameters, specifically S11 and S21, obtained using a Vector Network Analyzer (VNA). Upon analyzing the data, I noticed columns labeled "Trc1_S11[U]" and "Trc2_S11[U]," and I would appreciate some clarification on their significance. Could you kindly explain what "Trc1" and "Trc2" represent in this context? I'm particularly interested in understanding their roles or relevance in our measurements.
Furthermore, I would like to inquire about the procedure for calculating the Electromagnetic Interference (EMI) Shielding Effectiveness (SE) in decibels (dB) using the raw S-parameter data obtained from the VNA. Could you please provide guidance or instructions on how to perform this calculation? Any relevant formulas or methodologies would be greatly appreciated.
I have attached the raw data file for your reference. Your expertise and insights on these matters would be invaluable in advancing our understanding and analysis of the collected data.
Thank you very much for your time and assistance. I look forward to your response.
Warm regards,
Bhushan Kumar
