I suggest that a suitable source for evaluating the shielding
effectiveness of a BLS is a multivibrator (square-wave source), with
attention to rise and fall times: not too slow and not ridiculously
fast. It's more representative of emitting sources than a canned antenna.

Hello experts and gurus!!
I need to simulate the performance of a BLS (board level shield) and I
am considering
using the IEEE Std 2716-2022 IEEE Guide for the Characterization of
the Effectiveness of Printed Circuit Board Level Shielding document.
This document is however an adaptation of
the methods of evaluating gaskets rather than a focused guide on BLS
performance.
Question: Does anyone have experience using this Guide as intended for
a BLS solution evaluation?
Another Question: Would someone guide me to a paper or experiment that
shows
a decent correlation of a simulated source in a BLS versus actual
measurements ?
Here's my concern: The problem of how to internally source a signal
for simulation and
measurement seems deceptively simple. Just put an antenna on the
inside of the
shield - right? Well, no. My concern is that the addition of the
shield compromises
the antenna characteristics and so inadvertently this results in
better (or worse) results.
With eager anticipation and appreciation for your help with this!!
