OM20 Universal Outdoor Modem
Downlink Frequency (MHz): Displays the input frequency into the LNB from the satellite,
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.

also referred known as Satellite downlink frequency. The user
must enter the LNB LO and OSC SIDEBAND of the LNB
before using this menu. The DOWNLINK FREQUENCY is a
calculated measurement of both the LNB LO and OSC SIDE
BAND. Once the menus are entered correctly, the user can
control the downlink Frequency from this menu.
{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 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.
