Esta é uma tabela de dBm, dBu ,Tensão e Unidades-S (S-units) .  dBm, dBu  e tensão são unidades métricas bem conhecidas, já Unidades-S (S-units) é um pouco desconhecida para quem não trabalha na área de radiofrequência. Medidor de S-units é uma especie de medidor de intensidade do sinal,  um medidor muito usado em receptores de comunicações , tais como rádio amador ou receptores de ondas curtas e de radiodifusão. As marcações da escala  de S-units são derivadas de um sistema de sinal de S1 a S9 como parte do código RST . Abaixo a tabela S do RST: 1- Sinal fraco, quase imperceptível2- Muito fraco3- Fraco4- Feira5- Bastante bom6- Bom7- Moderadamente forte8- Forte9- Sinais muito fortes Tabela de dBm para dBu – Tensão e Units-S dBm(R = 50 ohm) dBu * (R = 75 Ohm,  0 dbu = 0,775 V) Tensão S-units(S9 = 100 UV, R = 50 Ohm) S-units(S9 = 50uV, R = 50 ohm) – 7 dBm – 17…
