SAT receiver
Input frequency menu
“Input frequency"
”Input level"
“Frequency offset”
“Tuner status”
The input frequency can be adjusted in a range of 950 ... 2150 MHz in steps of 125
kHz-steps. The current signal strength as well as the frequency offset of the input sig-
nal can be queried.
The displayed frequency offset is defined as follows: offset = received frequency - set
frequency. The software is tracking the frequency until the tuner is locked (tuner sta-
tus). The current status (locked/unlocked) can be queried. For monitoring the parame-
ters (input level, frequency offset and tuner status) a warning- and an alarm threshold
can be defined.
Symbol rate
Menu “Input symbol rate”
The symbol rate of the input signal is to be adjusted acc. to the input signal. It can be
set in a range from 1 ... 45 MSym/s (Device-status G2;
4 ... 45 MSym/s for device-status G1) in steps of 0.1kSym/s. (Device-status see chap-
ter “Menu operation/Miscellaneous/Module info”)
Code rate input signal
Menu “Input coderate”
The code rate of the input signal can be queried.
Carrier to noise
Menu “Input C/N”
The C/N ratio of the input signal is measured and can be queried. A warning- or an
alarm threshold can be defined.
Bit Error Rate
Menu “Input BER after V.”
The BER of the MPEG signal can be queried after the Viterbi decoding. A warning- or
an alarm threshold can be defined.
LNC remote supply
voltage Menu “LNC supp-
ly”
The LNC remote supply voltage is used for the direction of the polarity and must be
defined with +13V (vertical) or +18V (horizontal).
LNC control
Menu “LNC 22kHz”
The LNC 22kHz control can be switched on and off. The 22kHz control signal is used
for the selection of the receiving frequency band.
