Measure units of power can be configured by software. Available values are:
dBµV, dBmV or dBm.
The LINK MARGIN function (LM) measures the reception quality of the data link
(in dBs) between the satellite and the receiving antenna. A positive value indicates the
signal is correct. The higher the value, the greater the operating margin for future
adverse conditions. A zero value indicates it is about to lose the link. Negative values
means pixelaciones or signal loss.
Once the antenna is well positioned, if you wish to measure the MER on other
transponders of the same satellite that are memorised in the instrument, you can
change the test point by pressing the key
wish to measure the MER for other satellites memorised in the instrument, before that
you have to orientate correctly the antenna and then, change satellite pressing the key.
[3]. The variation between satellites and transponders depends on how you set the
table of channels loaded into the SATHUNTER+.
In addition, the SATHUNTER+ can measure the VBER for DVB-S or DSS and
the LBER for DVB-S2 (see figures 14 and 15). In order to do this, the SATHUNTER+
should be configured using the PROMAX software.
