This paper discusses a field measurement method. based on a two-antenna setup. to qualify the transmission of transient signals inside a GTEM cell. The transmission characteristic of the GTEM1250 is evaluated by the Pearson correlation coefficient (PCC) and is presented with a heatmap. https://www.lightemupsequences.com/deal-find-14K-Gold-plated-Lobster-Closure-Freshwater-Pearl-Bracelet-super-grab/
