.
Medición de Voltajes
1. Medición de voltaje:
- El voltaje de entrada al Receptor
es de 120V de Corriente Alterna.
Un generador de patrones con
formato NTSC se conecta a la
entrada de la antena. (Patrón de
Barras de Colores con 100 IREs
para el Blanco y 7.5 IREs para el
Negro.)
- Los ajustes de los Menus Picture y
Audio se normalizan.
En el Menú Set-Up, en la opción
ANTENA, se selecciona el modo de
CABLE.
El nivel de Volumen se minimiza.
De los modos TV y Video,
seleccionar el modo TV.
Seleccionar modo Estereo del
Audio.
- Las mediciones de los voltajes
son nominales y pueden variar
hasta 10% en componentes en
funcionamiento. Las lecturas
de los voltajes pueden variar
por la potencia de la señal y el
contenido de la imagen.
- Las fuentes de voltajes son
nominales.
2. El símbolo indica el tipo de tierra
que se utiliza en la conexión del
medidor.
PRECAUCION: Si no se utiliza la
conexión a la tierra adecuada, se
obtendrán mediciones equivocadas
y podría dañar el equipo de
medición.
Medición de Formas de Onda
1. Un símbolo como indica el punto
para medir una señal. (La medición
puede hacerse en el punto con
mayor accesibilidad, siempre que
sea común al indicado.)
2. Se midieron utilizando un generador
con formato NTSC conectado a la
terminal de la antena. (Patrón de 8
Barras de Colores EAI, formato
NTSC de 100 IREs para el Blanco y
7.5 IREs para el Negro.)
3. Los ajustes de usuario de los Menus
PICTURE y AUDIO se normalizaron.
Posteriormente el nivel de volumen
se ajusta al mínimo.
4. Las formas de onda de Video y
Color fueron tomadas con un
osciloscopio de banda alta y con
un punta de prueba de baja
capacitancia (10 a 1). La forma y
amplitud de las ondas puede
variar según el tipo de
osciloscopio que se utilice y sus
características.
5. El símbolo de tierra que
aparece junto al número de la
forma de onda, indica que se
utiliza conexión a Tierra Caliente
en el extremo negativo de la
punta de prueba.
PRECAUCION: Si no se utiliza la
conexión a la tierra adecuada, se
obtendrán mediciones equivocadas
y podría dañar el equipo de
medición.
