Dali Matrix PS System Installation and Commissioning Guide
Dali Wireless Proprietary and Confidential | DW-MAN-036 Rev 06
The Class B device described in this Installation and Commissioning Guide only has a
composite output power of 33 dBm. With a typical antenna gain of 5 dB and distribution
loss of cable and passive components, it will not exceed the 5 Watt ERP limit. See
Signal Booster Installation Guidelines shown below.
Signal Booster Installation Guidelines
In general, the ERP of the output noise within the pass band should not exceed the level
of -43 dBm in 10 kHz measurement bandwidth. The ERP of the output noise outside of the
passband by more than 1 MHz should not exceed the level of -70 dBm in 10 kHz measurement
bandwidth. The ERP of intermodulation products should not exceed -30 dBm in 10 kHz
measurement bandwidth.
The device shall NOT exceed the 5 Watt (37dBm) ERP limit.
In order to achieve this 37dBm
ERP limit, the “Maximum Power Output” of the device minus the “Distribution Loss” plus the
“Antenna Gain” MUST be smaller than 37dBm. In other words, once an antenna is selected with
certain gain, installer must calculate the minimum Distribution Loss required not to exceed the
37dBm limit. Distribution Loss is defined as the loss in cables and splitters combiners. The
sections below provides examples on how the minimum “Distribution Loss” is calculated for
different Power Output and Antenna Gain.
Calibration Modes
Units are calibrated for 2 W or 5 W depending on the output power required:
Mode A: 2 W
Mode B: 5 W
