2 – LEVEL/POWER
Please do first:
−
Recall a setup previously saved in a numerical table
of parameters.
Refer to « Parameters »
−
Or choose directly a frequency, an ANA (analog)
DVB-S, DVB-S2 or DSS (digital) standard, a high band
or a low band as well as a V (vertical) , H (horizontal) R (right) or L (left) polarization
corresponding to a transponder (choose first the band and then the frequency).
According to the standard selected (analog or digital); the instrument will automatically do the
level measure. In digital, the channel bandwidth is analyzed and then a power measurement is
calculated and displayed.
In addition to the measure of the carrier, you will have the following values: C/N (carrier/noise),
VLNB ( LNB voltage) and ILNB (LNB current).
For a good signal, the level must be between 47 and 77 dBµV.
