THEORY OF OPERATION
Description
The MARK-IV VHF Narrowband Signal Boosteris a stand-alone bi-directional &
multi-channel Signal Conditioner that performs on-channel processing
(narrowband filtering, automatic gain control and output level control) on
the received signals and provides a composite equalized multi-channel
signal suitable to drive its internal high-power amplifiers that feed the RF Tx
Output signals.
The core Digital Signals Processor (DSP) board uses state-of-art reconfigurable
logic to perform digital signal processing (channelization) thanks to its highspeed parallel hardware, high speed/performance Analog-to-Digital
Converters (ADCs) and Digital-to-Analog Converters (DACs) to interface with
the analog (Radio Frequency) world. Advanced digital filtering techniques
deliver low group delay and excellent phase linearity to support current
analog transmissions as well as new digital encoding systems.
High-linearity/low-noise analog interface hardware provides pass-band
filtering and gain stages to perform proper signal conditioning to interface
with the DSP digital core sub-system.
Discrete Digital I/O alarms are available for external monitoring.
A built-in Web Server provides a Graphical User Interface (GUI) to ease in
remote monitoring & control. Access is obtained via a PC’s Web Browser
and a TCP/IP connection to the Unit.

INITIAL CONFIGURATION
Canam Technology’s Equipment is factory configured. All setup
and wiring is performed by Canam’s Personnel. There is no need to
disconnect the equipment unless the units should be serviced.
If any module should be disconnected, it should only be done by
qualified technical personnel.
The unit operates stand-alone and only requires initial configuration, by
means of the Web Server Interface (over its LAN Ethernet interface).
The following guidelines provide information on how to get started with the
unit.
Make sure the power switch is OFF, and plug the AC power cord into
the IEC inlet receptacle.
Provide a connection from the off-air antenna interface to Antenna Rx
Input.
Provide a connection from the in-tunnel (in-building) antenna point-ofinterface to the RF Tx Output.
The dry-contact alarms are available on a pluggable mini-terminal

Now the device is ready for management functions using the web-browser
on the PC computer.
E.1 General guidelines regarding RF connections & operations with test
instruments
 Mute the MCPA prior to connect a signal source to Antenna Rx Input.
 Avoid excessive input power.
o Do not drive the input signal above -30 dBm, which is the
recommended maximum input level (composite).
 Make sure your RF Test Instrument (Communications Monitor, Spectrum
Analyzer, etc) has an input port rated for high RF power.
o Do not exceed the test-instrument’s input rating.
 The system has been limited to a maximum gain of 120 dB. A -100 dBm
sensitivity will limit to +20dBm maximum output, and so on. For
example, to set one channel to +27 dBm desired output, the user may
choose to set the RX Threshold to -90 dBm (or -93 dBm minimum)

“Control by:”
For the “MCPAs’ MUTE” and “Reflected Power Alarm Reset” commands, the
user can set the preferred control method by choosing Software or Hardware
in the “Control by” field.
a. If the user chooses hardware control, the controller will respond to the
opto-isolated inputs located in the DB-25 to screw terminals break-out
board and the software commands for these two parameters will have
no effect.
When “Control by Hardware” is selected the MCPA is automatically
unmuted unless the corresponding opto-isolated input is energized.
b. On the other hand, if the user chooses software control, the controller
will respond to these software commands instead of to the optoisolated inputs.

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.

In this page the user can configure the filters as follow:
The “Apply to all filters” section allows configuring all filters using the same
Rx Threshold, Hysteresis, Fine-Tune Output Level and Tx Enable / CTCSS
Tone Enable / AGC enable status.
Pressing the “Apply” button (it is enabled upon a setting change) the
values in the fields will be applied to all filters.

How to update operational settings?
Write down the desired value in corresponding field.
Press enter or “Apply” button for the system to validate the data.
Using the checkboxes click once and then press “Apply” button.
Useful Tips for configuring Filters
Center frequency corresponds to the filter-window center. For
narrowband windows, please make sure the programmed frequency
corresponds to the actual radio signal frequency to avoid interference.
The Fine Tune Output Level setting is used for adjusting down the carrier
power level on an individual “per-window” basis, and provides around
5 dB fine-tuning range.
