Methods and systems are disclosed for analyzing interference caused by electromagnetic and other radiated emissions. The adapter kit includes a multi-sectioned chute, which establishes a discharge communication path between the mower and the collection bag, and a frame for retaining the chute, collection bag, and shield. Accordingly, in a ground monitoring center, before satellite launching, there are mapped the output power value of the high power amplifier and the DC voltage level of the channel amplifier per each command step assigned to an FGM or an ALC mode. Gas-containing heat exchanging gaps for exchanging heat with the substrate extend between the heat transfer protrusions and the substrate.
