Signal boosters such as the M4DBDA8 generate radio signals and,
therefore, electromagnetic fields. The technical personnel should
have a complete understanding of FCC CFR Title 47 sections 1.1307
and 1.1310. Recommendations are included in this Manual, but
they do not substitute the FCC guidelines.
M4DBDA8 Key Features:
Narrowband Class A Signal Booster, per FCC Part 90.
Maximum Output Power at the antenna port +37 dBm per
carrier.
AGC circuit provides a constant output power, regardless of
the input power.
This device may require the use of antennas for proper functioning,
depending on the application. The installation of the antennas
should be performed by qualified technical personnel. All antennas
should be fixed mounted and physically secured to one location
The people must be away from the antennas at least 1.0 meters to
comply with the RF Human Maximum Permissible Exposure limits, as
long as the antenna system gain is lower than 11.3 dBi. If greater
gain is used the separation should be increased, please refer to the
FCC Rules.
If service should be performed on the antenna, please shut down
the transmitter or lower its power in order to comply with the
maximum permissible exposure.

Section D. THEORY OF OPERATION
D.1 DESCRIPTION
The M4DBDA8 is 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 high-
speed 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.

E.1 GENERAL GUIDELINES REGARDING RF CONNECTIONS &
OPERATIONS WITH TEST INSTRUMENTS
Mute the MCPA prior to connect a signal source to the DONOR/BASE
T/R PORT or SERVICE/SIDE T/R PORT.
Avoid excessive input power.
o Do not drive the input signal above -20 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).

F.2.3 MAIN SETTINGS PAGE
Figure 11 – Main Settings page
The Main Settings page is for configuring general system-level macro settings.
F.2.3.1 Maximum Desired Output Level per filter(dBm):
Allows the configuration of the output level such as the maximum gain
per sub-band 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.
CANAM TECHNOLOGY, INC. (CTI)
MARK-IVD 800MHZ NARROWBAND SIGNAL BOOSTER M4DBDA8 O&M MANUAL
Page 39 of 46
Rev1 May/2015
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:
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) <= Min 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.
o The Desired Output (Set-point) values are limited by this constraint.
o 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.
F.2.3.2 Input Attenuation Control

F.2.3.3 Pilot test carrier
The pilot test carrier is related to each bank first channel at current first
channel frequency.
The test carrier may be ON (transmitting) when the pilot test carrier setting is
enabled and the first filter in each bank has checked Tx Enable.
F.2.3.4 MCPA Control:
For the “Output MCPA Mute” and “Reset 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 ECM I/O DB25 Connector and the
software commands for these two parameters will have no effect.
The Reset Reflected Power Alarm command mapped to ECM I/O DB25
Connector can be controlled through pins 3 and 4 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
The Power Amplifier Mute command mapped to ECM I/O DB25
Connector can be controlled through pins 1 and 2 for both Service Side
(DL Tx) and Donor Base (UL Tx) outputs.
When “Control by Hardware” is selected the UL and DL MCPAs are
automatically un-muted 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 opto-isolated
inputs.
