Parameter
Description
On
Allows to enable/disable each filter
Frequency
Configures center frequency of each filter
Bandwidth filter control for
narrow-band version only
There are up to five available filters (depending on
factory setup) to adjust the trade-off between rejection
to undesired signals and delay
Fine gain control
Each channel gain can be fine adjusted
RF input power
Shows RF input level for each channel
Signal detection
With this indicator, system shows if signal is detected at
input, according to squelch threshold. Moreover, with
Squelch Mode = ‘Linked’, UL shows no signal if signal is
not detected in the same DL channel even if UL signal
exceed squelch threshold. Similarly, with simplex mode
enabled, if one signal is detected at DL band, all UL
filters will show “No signal”
RF output power
Shows estimation for RF output level for each channel,
according to programmed gain and AGC control. Shows
