    Notes, Cautions, and Warnings This is a Class B Booster. Part 90 (Class B) Signal Boosters WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC Licensee to operate this device.
  • Page 4 Introduction There are three major components to the Tower-4 system; the Head-End hardware, the Distributed Antenna System (DAS) hardware, and the Site-Wide Network (SWN). Signals from the SWN are input to the Downlink (DL) Head-End (HE) hardware. These signals are filtered and amplified by the HE DL, and fed into the DAS.

    The WTC firmware allows up to eight channels in uplink mode but other firmware is available from AMDI that allows up to sixteen channels per DSP module. The ULW8 has six channels. The GUI hides the GUI controls for the channels beyond those six since the settings read from the board tell the GUI program that for the “Up Link Window 8”...
  • Page 64 As you can see in the figure above, for each channel the GUI provides controls that specify these values: Channel Frequency (MHz) Channel filter bandwidth Channel filter order Output AGC setpoint (dBm) Squelch A and B types Squelch A and B values The GUI also provides the following outputs: Squelch A and B ON or OFF indicators Channel Input signal level (dBm)

    A filter with an order of 6 provides an input to output delay of about 24 microseconds but the filter transitions from its passband to its stop bands slowly. A filter with an order of 80, on the other hand has sharp edges but a longer delay.
  • Page 66 Notice that the BW: is set to 3 MHz. The BW control lets the user select from 50kHz, 100 kHz, 150 kHz, 200 kHz, 250 kHz, 500 kHz, 1 MHz, 1.5 MHz, 2 MHz, 2.5 MHz, 3 MHz, 3.5 MHz, 4 MHz, 5 MHz or 5.5 MHz.
  • Page 67 The pushbutton labeled “Update Firmware” is used to write new firmware into the DSP module. It lets the user select a “.BIT” file to load. This should only be done when AMDI sends a new firmware file and the new file has been loaded onto the PC. The present firmware file is on the PC named AmdiDspWtc.bit.
