Debido al cambio de 5 a 10 mA, la variación del canal E es pequeña comparada con los otros canales: Aprox. 0.7 dB

Considerando Potencias

En los canales C, D y E. la potencia de 5 mA es de la misma magnitud que el nivel de ruido del sistema. Lo cual se debe revisar. El canal E, no tiene la misma sensibilidad que los demas canales.
