temperature rises.
3-3.EXTURN ATT Extra-attenuation values. Input corresponding attenuation value :
Automatic (default)
The equipment will be burned due to incorrect settings
Input signal: -15~-25dB; Attenuation: 30 dB
Input signal: -25~-35dB; Attenuation: 20 dB
Input signal: -35~-45dB; Attenuation: 10dB
Input signal:
＜
-45dB; Attenuation: 0dB
The above attenuation value applies to -15~-60 dB RF signal
strength, optical fiber received signal strength should plus 30 dB based on
RF signal strength.
This item is default as AUTO, no need to set. If it is set at a fixed attenuation, you have
to test the strength of input signal according to list above and check 1-4, the same
illustration with 1-4.
3-4.MAX input power Preamplifier output too large protection point, unit: V. This
is protection voltage (default value: 2.5V) of preamp when signal suddenly turn
stronger or produce self-excitation, no need to set and can not exceed 3.5V, or amplifier
will be burned down because of self-excitation.
3-5.MAX FORD POWER Max- output power protection point. Corresponding to
output power display (1-1), and then adjust the max- output power protection point, the
general maximum add 40%, for example, a 50 W repeater, the protection point is
70W,please increase the protection point to 85 W if the display power fluctuations lead
to frequent protection.
3-6 MAX RER POWER Maximum reflection protection point Corresponding to
reflection power display 1-2 .Generally it is the 4 times of reflection power display
