Configuring RF Input Power and Low Power
Thresholds
Before activating RF modules in the host, you must set the maximum input power
supplied by the off-air signal source or base station. This value should match the signal
source power after the attenuation equipment. The maximum downlink (DL) input power
is based on the power when all channels in a frequency band are active.
For information on applying attenuation once the RF modules are active, see
DL and
UL Gain Commissioning
.
For each RF module in the hdHost PS or airhost PS, configure the following RF
settings.
Field
Description
Range
DL Input Maximum Power
Sets the maximum downlink RF
power supplied from the base
station or off-air source
hdHost PS: -10 to +10 dBm
airHost PS: -95 to -10 dBm
DL Input Low Power Alarm
Sets a threshold for the low input
power alarm. When the input
power falls below this threshold,
the RF module displays a low
power alarm
-128.00 dBm disables the alarm
Simplex/Duplex
Sets the connection type
Simplex
First, configure the attenuation equipment to reduce the base station or off-air power to
the appropriate levels. Next, for each band in the host, set the maximum composite DL
input power level to the expected maximum level from the base station or off-air source.
This value should match the power levels after the attenuation equipment.
For example, if the maximum composite value after the attenuation equipment is
0 dBm, then set the
DL Input Maximum Power
value to 0 dBm.
To configure the maximum DL input power and low power thresholds:
1. Select an hdHost PS or airHost PS in the system tree and click
to display the
Band Information view.
