Channel Bandwidth
Current settings is displayed This can be modified using the Installation pages, as
described in Installation pages on
page 6-51.
Max Receive Modulation Mode
This is the maximum mode the unit will use as its adaptive modulation. By default the
Max Receive Modulation Mode is the highest mode available.
For minimum error rates, set the maximum modulation mode to the minimum
necessary to carry the required traffic.
Ethernet Capped Max Wireless Speed
When enabled, this option will cap the wireless speed to a mode that the connected
Ethernet connection can sustain.
Maximum Transmit Power
This specifies the maximum transmit power in dBm of the system. It is country
dependent and although the user can change this in 1dB steps, it will be limited to that
country’s regulations.
NOTE
UK requirement: In the UK there is a legal requirement to provide a
minimum of 19 dB of transmit power control range. When the equipment is
operating with a UK License Key, an additional facility is provided on the
configuration page that allows the transmitted power to be reduced by 19 dB
compared to the maximum allowed with a simple single step control..
Why Reduce Transmit Power? If the link losses are low and the link data
rate and availability targets are being easily achieved, the transmitted power
level may be reduced with a consequent benefit to other users of the band,
such as fixed satellite links.
Antenna Gain, Cable Loss and EIRP
Only displayed when Platform Variant is set to “Connectorized” in the Installation
pages. For more information about the configuration of connectorized PTP 600 units,
refer to Software and features on pag
e 8-3.
Encryption Algorithm, Encryption Key and Confirm Encryption Key
Only displayed when AES encryption is enabled by license key. For more information,
refer to Enabling AES encryption at the wireless interface on
page 6-96.
