6.CongurationManager
All real-time data displayed in the conguration manager, is a subset from the real data. The data communication is not
showing all data, to limit the load on the data bus.
6.1 PL TAB
Below there are 4 real-time parameters, Alarm (red colored), Pulse Count, Sinus / Gauss and internal label detected
counter. The alarm is indicating that the two blue markers are simultaneous in the green area, when the label is gone this
alarm will immediately dim. The lamp on the antenna will be triggered by this signal but has a hold function. The channel and
corresponding frequency will always give a predicted value of the center frequency of the label. When there is no label, it will
predict it in the noise. This results in random changes.
The counter is an internal counter and independent from the counter used for easi/net. The counter has a reset button ‘clear’.
During switching on the unit, the FPGA on board has to be booted. The FPGA status tells if this process succeeded.
A View Spectrum button will open another window with a real-time plot of the spectrum.
The button Save & Close saves all the control parameters into a ash and closes this window. During next boot, the new
written control parameters will be loaded.
6.2 PL RX TAB
This is the main window that gives a quick overview of the
system dynamics. There are two displays showing information of the
actual Q and number of valids. In this display is a green
colored range. This gives the threshold of the receiver for
generating alarm. When both blue markers are simultaneous in
the green area an alarm will be generated. The zoom control is
centered at the max. value of the Q-factor and the min. value of
the Valids.
The control SNR is automated in case Automatic Sensitivity
Control (ASC) is allways activated. During booting of the unit, the
environment of the antenna must be clean from labels.
Start control is default set to a safe value (-3.2dB). This must be
save for almost all situations. When the installation of all units
is done and stable, you can test if the performance is ok. The
performance can be tweaked to its highest level by changing the Start
control to a lower loss value. The dB scale is indicating the expected
sensitivity performance compared to the perfect situation with a
label of Q=80. In situations of using labels with very low Q, it is
giving the most boost. High Q labels benet not so much from changing this control.
6.3 PL TX TAB
The transmitter can be switched on/off with TX On.
Temperature is monitored and the TX RF power is reduced or switched off when the temperature is above normal.
To prevent label from deactivating, a power control can be used. This control will reduce the RF power at the antenna when
a label enters in its possible deactivation level. The Power meter indicates the actual power of the RF power amplier, where
128 is max. power and 0 is min. power.
