Specifications - Promax SKYHUNTER Manual De Instrucciones

In the SKYHUNTER, the ultimate measurement to determinate the signal quality is
the modulation error ratio (MER), this is directly related to the CBER (Channel Bit Error
Rate). This threshold may be reprogrammed according to the signal quality level
specified by each operator.
First, the instrument detects the signal sources in the full satellite band. In a second
step, it obtains the qualitative measurement for signals detected (the instrument
displays 'ber' when signal level is equivalent to poor quality and 'BER' when is
equivalent to good quality). Finally, it shows simultaneously all the quantitative
measurements on the screen (Power, CBER and MER).
The instrument is a useful tool when installing either a specific service or satellite, or
a series of services or satellites. Its specific use is determined by the instrument
programming, which in turn depends on the country or geographical area.
The SKYHUNTER has been specially designed to stand rough working conditions,
it includes a back-light display and offers long battery life and short charging times.
