CANAM TECHNOLOGY, INC. (CTI) MARK-IV VHF NARROWBAND SIGNAL BOOSTER OPERATIONS & MAINTENANCE (O&M) MANUAL Page 32 of 37 Rev0 May/2011 Maximum Desired Output Level per filter(dBm): Allows the configuration of the output level such as the maximum gain per path will be less than or equal to 120dB. The specified value cannot be modified in case the maximum gain would be greater or equal than 120dB. The Maximum Desired Output Level is the user setting or goal set point for the RF Output power level per filter window, subject to the following two constraints: 1. Maximum Gain of 120dB: The maximum gain for any filter window may not exceed 120dB. Due to the Automatic Gain Control (AGC) function, the system calculates the Gain starting at the minimum signal level able to be received, which is defined by the Rx Threshold (Squelch) setting. Signals coming in at that threshold level will be amplified a maximum of 120 dB. Therefore: o Actual Maximum Desired Output (Set-point) <= Lowest Rx Threshold + 120dB. THUS: The User entered Set-point may be automatically reduced to meet the maximum 120dB Gain. For example, this will happen if the User reduces an Rx Threshold setting. below the lowest previously defined. o The Desired Output (Set-point) values are limited by this constraint. o NOTE: This equation is driven by the lowest Rx Threshold value in the filters bank, i.e. if at least one filter is set lower than the rest, that value drives the output Set-Point for the entire bank. Press the “Apply” button to apply changes to the current state. The current state applied to system is saved to the controller’s internal nonvolatile memory for effective recovery after a power loss or system reset. Pilot Test Carrier:
