P8R Satellite Receiver QPSK/8PSK

Models
Table 2.7 applies to models M2/P8R/942[A][B][C][D]
#1 - #2 (L-band Inputs)
Connect the L-band output of a suitable LNB to the
Type F connector either directly or via a suitable
attenuator giving adequate consideration to lightning
and surge protection - see Section 2.3.4, Outdoor
Antenna. The active input is chosen using the Satellite
Input Menu (#4).
In most cases an attenuator will not be required, but one should be used
where:
·
The required input signal exceeds the specified maximum permissible
level (-25 dBm).
·
The downlead is a short length of low-loss cable and the LNB in use
has a poor return loss (7 dB min).
·
The Receiver is receiving one of many carriers in a multi-carrier FDM
system and the required signal is close to the specified maximum
permissible level.
The specification for this connector is given in Table B.14.

1. The Receiver provides dc power to drive an LNB, via the active L-band input connector. Do not
connect equipment other than an LNB to this connector. Failure to do this may result in damage to
the external equipment.
2. The F-type connector is not suitable for repeated connection and disconnection. If it is intended to
use the Receiver in this way, fit a sacrificial connector and make connections to it.
