10.1 Lamp for Modulation Cell
10.1.1 Lamp for Power on
When this lamp is luminous, it means the power supply for modulation cell is normal.
10.1.2 Lamp for Video AGC
When video output is controlled by AGC, this lamp is light.
10.2 Lamp for Amplifier Cell
10.2.1 Lamp for Power on
When it is power on, the voltage of 5V is supplied normally, this green lamp is luminous.
10.2.2 Lamp for RF
When the RF SWITCH on the main menu is set to “ON”, this green lamp is light.
10.2.3 Lamp for Video
While output power is normal, this lamp is light.
10.2.4 Lamp for REMOTE
In the page of Set, if Remote is enabled, this yellow light is illuminant.
10.2.5 Lamp for TEMP
When the amplifier temperature is higher than 70
℃
, if temperature exceeds 85
℃
,it will
power off immediately.
10.2.6 Lamp for VSWR
If reflected power is higher than 2% of rated power, the lamp is light; higher than 4% of
power, it will decrease output power to decrease reflected power; when it is higher than 5%, it may
happen that: the software power off the output, or the hardware circuit switch off the power supply,
then power on again.
