Radio Configuration

ATPC Max Power: This is the maximum output power (in dBm) that the ODU will
deliver. This is controlled by the FCC License ATPC output power allowed.
ATPC Step Size: This is the amount (in dBm) that the Transmitter will alter the output
power per command from the far end radio. Step size is user selectable from 1-5 dBm.
Larger step sizes can track faster fading events but can cause "hits" if the far end
receiver cannot track the change. A small step size is less likely to result in "hits" but
may cause outages due to fast fading driving the far end receive signal below threshold.
Channel_bw: Displays the current channel band width.
Datapattern: Displays current datapattern setting. The settings could be either
External / Internal. Normal operation mode is External. Internal traffic is used to
generate random data to measure BER, All user data from GigE ports will be dropped
when the datapath is set to internal mode.
Frequency: Displays the Transmit and Receive Frequency of the radio in MHz
Power: Transmit power of the unit in dBm. Please note that there is no internal
checking of maximum power. Please check the datasheet for your frequency for
maximum power for a specific modulation. Setting the unit at a power higher than
allowed by your FCC license is strictly forbidden.
Loopback Mode: Displays the current Loopback settings.
Modulation: Displays the current modulation from QPSK to 256QAM.
Target RSSI: This is the RSSI value programmed as the nominal receive signal level (in
dB determined during the path design). This is used by ATPC.
Temp: Internal temperature displayed in Celsius. Please note that the temperature
displayed could be 10
product datasheet are outside ratings not internal temperature ratings.
UTYPE: Displays the current Unit type.

System Configuration

The following settings are displayed in the "Sysinfo" page under System Configuration
as either ON or OFF.
ACM – Controls whether Adaptive Code Modulation (ACM) is enabled
Alignment – Controls whether Alignment mode is
o Disabled ("Off") - The RSSI LED on the ODU will update once every 4
seconds
