61-65-50 UserMan page 3 of 24 For Class A Unintentional Radiators This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
61-65-50 UserMan page 4 of 24 Antenna System Installation The antenna or signal distribution system consists of two branches. An uplink branch typically uses an outdoor mounted, unidirectional gain antenna such as a yagi and a downlink signal radiating system consisting of a network of zero-gain whip antennas or lengths of radiating cable usually mounted inside of the structure. Even though the antenna system may not be supplied or installed by TX RX Systems.

61-65-50 UserMan page 7 of 24 GENERAL DESCRIPTION Signal boosters extend radio coverage into areas where abrupt propagation losses prevent reliable communication. This system receives an RF signal, raises its power level, and couples it to an antenna or leaky (radiating) coaxial cable system so that it can be re-radiated. No frequency translation (conversion) occurs with this device.

It is the customer’s responsibility to make sure these devices are mounted safely and in compliance with local building codes. CONNECTIONS All cabling connections to the booster should be made and checked for correctness prior to powering up the system.

Modulation is not necessary. The other set of contacts changes state when any of a number of fault conditions arises within the electronics such as current drain outside of the expected operating range in some module.

The following startup sequence occurs. 5) The LCD display should appear similar to Figure 6 after the self check is complete. 1) At turn-on, the four status LEDs on the front panel glow red for about 5 seconds as the result of entering a self-check mode.

61-65-50 UserMan page 15 of 24 Attenuator Module: Green only indicating DC power is applied to the card. OLC LIGHT BARS Ideally, there should be little or no light bar activity. Each light bar segment represents an average 3 dB of OLC gain reduction. OLC (output level control) is meant to reduce gain for transient episodes of very strong signals.
61-65-50 UserMan page 16 of 24 NOTE Note: A reduction in system gain will also result in an equal reduction in the OLC dynamic range, refer to the section titled “OLC” on page 16. SET OUTPUT LEVEL Allows the output power for the uplink and downlink channels to be independently adjusted in 0.5 dB increments up to +31 dBm. Note that the OLC circuitry will maintain the systems output level at the values you have selected in this menu.

The average OLC attenuation used when the OLC was active is given both for individual days and over the entire past 100 days. The percentage of time the OLC was active is also given for both individual days and over the past 100 days.

In this way, a map of the systems performance can be generated. 4) For signals coming from a fixed antenna or station, record the level of all the desired incoming signals for future reference.

61-65-50 UserMan page 20 of 24 NOTE Note: Power to the SB II cabinet must be tur ned OFF dur ing the power amplifier replacement process. 1) Remove the Phillips screws which hold the amplifier into place, refer to Figure 10. The nuts holding the screws are pressed into the cabinet and will remain in place when the screws are removed. 2) Slide the amplifier towards the bottom of the cabinet as far as it will go. This will allow the top RF connector to clear the opening.

Once the card is seated into place properly tighten the thumb screws. The SB II low level and mid level amplifier stages are field replaceable by simply removing the module and plugging in a replacement. These modules are HOT switchable meaning they can be swapped without powering down the system.
