Acquisition Mode
■
the satellite carrier frequency (lock acquisition search range). Options:
Narrow
❑
Wide
❑
NOTE: Wide search is the normal operation mode of the receiver frequency acquisition scan.
Narrow Search mode should be used when symbol rate of the input is lower than 5 MBd.
Frequency Drift Compensation – Compensate for LNB frequency drift, see

BER Threshold (DVB-S only) – Sets the threshold limit to raise the Bit Error Rate alarm.
■
Range: 0.00001 (0.1x10-4) – 0.1.
PER Threshold (DVB-S2 only) – Sets the threshold limit to raise Packet Error Rate alarm.
■
Range: 0.00000001 (0.1x10-7) – 0.1.
Attenuation Level
■
1
Gain – Internal gain to improve signal strength.
■
Carrier Frequency properties – Radio buttons selection, therefore only one is selected at a
■
time. Changing the value on one option, changes the other one automatically:
L-Band Frequency Range – Sets the L-Band frequency of the receiver local oscillator.
❑
Range: 950,000 – 2,150,000 (in kHz), adjustable in 125 kHz steps.
Frequency for the band selected in LNB – Sets the frequency of the satellite, according
❑
to the satellite transmitting frequency, adjustable in .125 kHz steps.
LNB (Low Noise Block) Properties:
■
Polarization – Antenna polarization. Options:
❑
• 13V (Vertical)
• 18V (Horizontal)
• Off
LNB Frequency Band – The default is Universal. Options:
❑
• Universal (9.75, 10.6)
• Universal Wide (9.75, 10.75)
• Ku
• C
LNB Local Oscillator Frequency (kHz) –
❑
For Universal and Universal Wide satellite frequencies, the LNB Local Oscillator
Frequency is set according to the 22 kHz Tone setting.
