Field description:
Band selective repeater
The band selective repeater, or the band selective part of a combined
repeater, can be turned on/off by clicking this box.
The PA boards and the AGC (Automatic Gain Control) are turned off
when the band selective repeater is switched off.
Downlink Low band edge
Displays the downlink low band edge related to the uplink low band edge.
The difference is depending on the system duplex spacing.
High band edge
The downlink high band edge related to the band width.
Gain
The maximum downlink gain, i.e. the total gain from antenna port to
antenna port.
Setting range: 45dB to 90dB
Uplink Set low band edge
The lower band edge for the uplink signal. The band edge frequency can
be increased or decreased by clicking the arrow buttons. The frequency is
changed in 12.5KHz steps. Values can be typed into the field as well.
Setting range for this field is depending on the system and BSA boards.
Set high band edge
For fixed BSA boards, this field displays the uplink high band edge related
to the band width. This band edge cannot be changed solely.
For adjustable BSA boards, this field is changeable and affects thus the
uplink high band edge and thereby the band width.
Gain
The maximum uplink gain, i.e. the total gain from antenna port to
antenna port.
Setting range: 45dB to 90dB
