Symbol Rate
Enter the number of mega-symbols per second (Msps).
Modulation
Select the modulation scheme (QPSK, 16QAM, 32QAM, or
64QAM).
Core Channel 1, 2, 3, and 4
Select the core channel input. (ASI BNC-1, ASI BNC-2, ASI BNC-3, DS3
BNC-1, DS3 BNC-2, DS3 BNC-3, E3 BNC-1, E3
VBNC-2, SMPTE BNC-3, T1RJ45-1, T1RJ45-2, E1RJ45-1,
E1RJ45-2, Ethernet RJ45-1, RS232, RS485, or none)
Data Rate (1, 2, 3, and 4)
Enter the data rate for the selected core channel. See also Section 3.4.6,
Determining Overall System Capacity Versus Bandwidth for more
information.
Invert Spectrum
On=Select On only if the modulation scheme that you
selected requires
it.
Off=Default.
NOTE: Set this to On only when an incoming signal needs to be inverted due
to a different conversion technique or compatibility with other equipment.
Sys BW
Displays the system’s maximum capacity (bandwidth) in MHz.
Utilization
Displays the percentage of utilization. This value updates dynamically, so
you can change the values on this screen to optimize system use. See
Section 3.5, Creating User Accounts (Administration Tab).
3.4.5 Setup–ODU Screen
The ODU (outdoor unit) screen on the Setup tab lets you define the following:
OpMode
Select Normal, or Align to drive the maximum signal to the antenna during alignment
procedures.
TX Mute
Select Mute or Not Muted.
TX Power
Enter a value between the minimum and maximum values that suits your modulation
type. If sites are too close, you may want to reduce power.
TX Frequency
Enter the transmit frequency between the minimum and maximum range values.
RX Frequency
Enter the receive frequency between the minimum and maximum range values.
