radiometrix ltd page 4 narrow band evaluation kit manual note : the carrier board should always be firmly bolted do wn to the main controller board mounting studs at all four corners, or the grounding of the carrier b oard will be compromised. this is especially important when high power transm itters are used with the aerial connected directly onto the bnc. in this case, any mismatch will cause significant ground currents to flow. figure 2: main controller board component layout figure 3: xx2m series carrier board figure 4: bim / smx series carrier board
