4.2.5 Tracked L-band Beam and Signal Strength Status via Terminal
The presently tracked L-band beam/s and signal strength/s can be found by entering:
LOG LBANDTRACKSTAT
The returned status will display information relating to any of the beams that are being actively tracked or
searched f or. The tracked L-band beam names will be f ound in quotation marks at the start of each line, i.e.
“25E”. The value after the beam name relates to the L-band beam frequency followed by the baud rate, which is
typically 1200 bps. The signal strength will be f ound in the 8th f ield along f or each beam line. Signal strengths
are output in dB and a value of 36.5dB or above is optimal.
When in
Auto
Beam
mode the terminal output will be similar to the below:

4.2.6 HDR Mode Configuration via Terminal
Enabling HDR mode can assist with L-band tracking when potential interference sources are present. HDR
Mode uses signal processing to dampen potential sources of RF distortion, at the cost of increased CPU
usage. It is recommended that if any L-band tracking issues are observed (intermittent, low or no signal) this
option is enabled.
HDR mode can be enabled by entering:
ITFRONTENDMODE LBAND HDR
HDR mode can be disabled by entering:
ITFRONTENDMODE LBAND CIC3
