OM20 Universal Outdoor Modem
Spectrum:
Spectral inversion may be required if the LNB LO is higher in frequency
than the LNB input frequency from the satellite. When LNB LO is higher
in frequency than the LNB input frequency, this creates a spectral
inversion and the IF Spectrum must be inverted to compensate.
Demodulation:
Spectral Mask:
Sweep Range (kHz):
Sweep Delay (sec):
Reacquisition Range (Hz):
Adj Carrier Pwr:
Fast Acquisition:
The maximum symbol rate for Fast Acquisition is 1028Ksps.
Fast Acquisition must be disabled for rates greater than 1028Ksps.
Only supports QPSK and 8PSK in a NON-DVB MODE.
Does not support spectral inversion applications.
TM116 – Rev. 1.2
{Normal, Inverted}
Allows the user to invert the direction of rotation for PSK
Demodulation. Normal meets IESS Specification.
{QPSK, BPSK, OQPSK, 8PSK, 16QAM}
Allows the user to select the demodulation type.
{Intelsat 0.35, DVB 0.35, DVB 0.25}
Allows the user to invert the direction of rotation for PSK
Modulation. Normal meets the IESS Specification.
{±0 to 255 kHz}
Allows the user to set the acquisition range for the
demodulator
{0.0 – 900.0 sec}
Allows the user to set the reacquisition delay time in
th
1/10
second increments.
{0 – 32000 Hz}
Allows the user to set the reacquisition sweep in 1 Hz
increments.
{Normal, Suppressed}
Allows the user to indicate adjacent carrier as Normal or
Suppressed (High Power). Unit will increase or decrease
post dissemination gain appropriately.
{DISABLED, ENABLED}
Allows the user to disable or enable the Rx fast
acquisition capability.
Limitations of Fast Acquisition:
