Revision 2
Automatic Level Control (ALC) threshold are also displayed and shown in tenths of a dBm. If the set
gain differs from the Max gain for example, this a sign that the ALC is active.
Output power field is displaying RMS power of the repeater measured at the antenna port. Different
modulation waveforms might have a slight impact on the measured value at the antenna port.
User has a possibility also to set up a periodic mode. The window will collect and update the data
displayed every two seconds.
5.2.6 Software
Software menu displays the actual application SW version, fallback application, boot loader version,
serial and article numbers, dates of manufacturing of the unit and its board units used in the actual
repeater product.
When logged in Extended user mode, there are allowed possibilities for Software upgrades, changing
of current application versions, and Reboot option. All actions such as SW upgrades and application
version swap require a command Set which must be followed by a reboot of the repeater for the
changes to properly apply.
