9.5.5 Down Link Set Up for a TDMA System
Down Link set up for a TDMA system is completed with a single RF carrier with all time
slots active. Down link peak power feature will prevent inadvertently setting the output
power level too high. The unit will automatically readjust the down link gain to limit
output power below the selected thresh hold. (See software section on peak power limit.)
Display, * Readings/Controls: Adjust base station input power to TX PWR IN. Set up
adjustments are always made with a single RF carrier. The following table gives the
system set up levels for a multi carrier system.
For multi-carrier systems adjust this level as follows:
DL RF Input Base Station Input Power Eko-1.9M Eko-1.9R
Controller Screen Tx 1.9Lzr Pwr: Tx 1.9Bse Pwr: DL PA Detect DL PA Detect
or Tx 800Lzr Pwr: Tx 800Bse Pwr: DL # Pwr dB: DL # Pwr dB
Single RF carrier -0 dBm 31 dBm 33 dBm 39 dBm
Two RF carriers -3 dBm 28 dBm 27 dBm 36 dBm
Four RF Carriers -6 dBm 25 dBm 24 dBm 33 dBm
Adjustment to these levels will allow EkoCel to operate to the proper power level as
indicated above.
