Mediciones de ruido de canales de JULIA:
- Desde sala de operaciones
Canal | 50 ohmios | 5 mA (-41dB) | 10 mA (-38dB) | 3dB |
---|---|---|---|---|
(dB) | ||||
C | 7.42 | 12.46 | 14.41 | 2.02 |

- Desde antena
50 ohmios | 5 mA (-41dB) | 10 mA (-38dB) | 3dB | |

8.1 | 10.71 | 12.33 | ||
E | 7.82 | 10.8 | 11.54 | 0.7 |
7.83 | 10.82 | 11.52 | ||
7.84 | 10.79 | 11.5 |
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
50 ohmios | Pot 5 mA | Pot 10 mA | Dif (dB) | |
---|---|---|---|---|
A | 14.74 | 20.88 | 42.02 | 3.04 |
B | 11.25 | 21.36 | 41.80 | 2.92 |
C | 6.07 | 6.53 | 12.68 | 2.88 |
D | 6.40 | 5.33 | 10.70 | 3.03 |
E | 6.07 | 5.96 | 8.12 | 1.34 |
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.
