2.4.3 RFU (Radio Frequency Unit)
The RFU (RF Unit) is a bi-directional amplifier that sharply filters out unwanted noise.
2.4.4 Duplexer
A duplexer is a device that combines two or more signals onto a common channel or
medium to increase its transmission efficiency.
2.4.5 PSU (Power Supply Unit)
The AC-DC adaptor supplies a steady DC power to the APEX19xx equipment by drawing
power from the general in-wall AC outlets.
2.4.6 NCU (Network Control Unit)
The NCU (Network Control Unit) is the control unit of the APEX19xx. The NCU controls and
monitors operational parameters, alarms, records event and performs many other functions.
2.4.7 ANTENNA REQUIREMENTS
ANTENNAS: please read your manufacturers antenna specifications before installation. Your
antenna will require a type “N” connection. The antenna, coax, and fittings must be 50
ohms impedance.
MAXIMUM ANTENNA SIZE CONNECTED TO THE APEX1933 REPEATER IS 12dBi,
The CDMA repeater requires antennas that operate in the desired frequency range of the
CDMA repeater. The APEX1933 Repeater has a frequency operating range of 1850 to 1915
MHz for the up- link, and 1930 to 1995 MHz for the downlink. Your antennas must operate
within these frequencies.
Failure to select the proper antennas will degrade the performance of your repeater.
2.4.8 ANTENNA ISOLATION & COAX CABLES
To protect wireless CDMA networks from interference caused by oscillation, the APEX1933
Repeater has internal automatic oscillation detection/control and auto shut down of the
repeater.
Improper installation practices could can initiate automatic shut-down of your repeater.
All repeaters require antenna isolation to prevent oscillation. The usable gain level of your
repeater is directly linked to the antenna isolation values. The maximum gain of your
repeater must be adjusted to a minimum of 10 dB lower than your antenna isolation values.
For example, if your antenna isolation value is 43 dB then your maximum usable repeater
gain is 33 dB.
APEX1933 USER MANUAL V1.2 Tech Support: 1-888-317-8766
9
Due to the variations of system layouts and requirements it is not possible to have one
procedure that will suffice every installation. You are strongly advised to acquire the services
of an RF system designer to calculate your antenna isolation requirements.
Ensure that your antennas are at the maximum possible distance apart. Do not place
antennas in close proximity to each other; otherwise you will activate the oscillation
detection process.
Coax cables should be low loss 50 ohm, and suitable for 1850 to 1915 / 1930 to 1995 MHz
band frequency.
Antenna connections should be clean and moisture free. Do not spray lubricant into the
connectors as this prevents the signal traveling through the coax. Use a cleaning solvent
that has no oil and does not leave any residue. High quality oil-less contact cleaner is
suitable.
All coax connectors must be water tight and wrapped with water proof tape. Any moisture
in the connectors will degrade or eliminate the signals.
2.4.9 ANTENNA CONNECTIONS ON THE APEX1933
The APEX1933 can be installed indoors. If mounted indoors ensure there is no elevated
room temperatures and free flowing air for cooling of the repeater.
Connect the antenna that is aimed at the Cell Tower to the bottom left side N connector.
Connect the antenna that is aimed towards the Area Fill (target site) to the bottom right
side N connector.
Connect your Ethernet cable to the connector socket located on the left side of the power
on LED light.
NOTE; Water proof boot cover for the Ethernet connection, contact your Repeater supplier.
2.4.10
Additional protection is gained if the reverse link maximum power level is adjusted to
prevent the possibility of sudden unwanted high input RF levels. This can happen in various
ways, mobile cellular vehicle boosters coming within range of the cellular repeaters,
malfunctioning cellular phones, or other stray signals.
ADJUSTING REVERSE LINK MAXIMUM POWER LEVEL.
The APEX1933 has an adjustable Maximum allowable RF Power limit. The maximum
allowable RF power limit is 33dBm. The digitally controlled attenuator will not permit RF
signal levels greater than 33dBm.
The user can decrease the maximum allowable RF transmit power from 33 dBm to 0.0dBm.
The microprocessor controlled digital attenuator will maintain the preset allowable RF
transmit power limit regardless of unwanted high input signal levels.
APEX1933 USER MANUAL V1.2 Tech Support: 1-888-317-8766

2.4.11 Calculating the Maximum Output Power allowed
The regulatory limits for maximum output power are specified in EIRP (equivalent isotro
pic radiated power). The EIRP level of a device will be installation dependent and final c
onfiguration is the responsiblity of the professional installer. However in general the fin
al EIRP can be calculated by adding the gain of the antenna used (specified in dBi) to
the output power available at the connector (specified in dBm) minus any cable loss.

• Easy Setup is a fast start function. The function measures Isolation, detects input level and
assign gain to achieve maximum output power. The function ends with the equipment set
to amplify signals in both directions within the confines of the band selection. Before
running easy setup, set the center frequency and bandwidth (refer to 4.3.3 part 2).
Maximum DL output power requires at least -10dBm input power and sufficient antenna
isolation.
• Isolation Check can be executed at anytime to measure isolation between the donor and
server antennas. Isolation Check momentarily disables service. Isolation check automatically
runs when factory default is initiated.
• Factory Default restores the amplifier to its initial state. The function ends with amplifiers
off, AGC mode off, gain set to minimum(15dB) and UL gain offset set to 0dB. Band selection
and all other system parameters are not changed. The featurs is usefull in claering abnormal
conditions.
• System Reset cycles the microprocessor unit. The function is similar to switching off/on the
equipment power switch.
5.5.2 Operating Control
• DL and UL Path Control allows the user to toggle on or off the power amplifiers.
• DL and UL Gain is available when AGC mode is off. The user may enter gain values
manually. Manual gain control is an alternative to automatic gain control (AGC). Manual
gain is disabled (grayed out) when AGC mode is on. Gain cannot be controlled manually
above the available gain found on the status page. The system will not allow gain to be
increased such that maximum output power (33dBm) is exceeded.
APEX1933 USER MANUAL V1.2 Tech Support: 1-888-317-8766
24
• Gain Tracking sets UL gain equal to DL gain. The feature helps maintain forward and
reverse link balance. The function control is grayed out when AGC mode is on.
• Automatic Gain Control :
- In contrast to manual gain control, automatic gain control (AGC) sets gain such that the
desired amplifier output level (33dBm) is automatically set.
- The user controls gain by adjusting the AGC level. The user may set the level from 0dBm to
33dBm. AGC can be used to control the signal level radiated from the server antennas.
- AGC may also be user to match the equipment to a DAS (distributed antenna system). AGC
level may be restricted by available gain and DL input power.
• UL Gain offset is used in conjunction with AGC to reduce the amount of amplification in
the reverse direction (uplink). In the cases UL offset is set to 0dB.
• Automatic Shutdown (ASD) :
- ASD temporarily shuts down the amplifier if the ASD level is exceeded. It is not necessary to
turn off ASD. ASD events are stored in the alarm history log. Repeated ASD events will
eventually shutdown the amplifier permanently and trigger the external shutdown lamp.
- ASD Level is set to 36dBm by default. It is not necessary to change the default level.
How to prevent saturation or over-modulation
1. Hardware function
Input : If this device detect an over input signal, input hardware ALC will automatically
activated over
power rating+2dB within 100ns to protect it and in case of over ALC range
turn to Thru-Path by activating a relay to prevent from occurring
saturation of AMP and Digital board.
Output : If this device detect an over output signal, output hardware ALC will
automatically activated over
power rating+2dB within 100ns to prevent from occurring over output power.
2. Software function to adjust the maximum power output and secure linear operation
AGC(Automatic Gain Control) : automatically control the output power not to exceed
over the set value.
ALC : activating in AGC off condition to prevent from occurring over-output power

5.5.3 Alarm Control
• Alarm response time may be set between 0 and 5 minutes.
• Alarm Mask allows the user to customize the type of alarms sent to the SNMP server when
remote monitoring is in use.
5.5.4 Band Select
• Band select sets the digital filter to the center frequency and bandwidth of the local
service for which the equipment is intended to amplify. Likewise, all other signals outside of
the selected Center Frequency and Bandwidth are rejected.
• The user can select one, two three distinct sections within the PCS band. Each of the 1st,
2nd and 3rd filter blocks can be set to 1MHz to 20MHz of Bandwidth. Only the downlink
center frequency is set by the user. The uplink center frequency is automatically set in
accordance with the downlink frequencies.
• Filter Rejection allows the user to change the digital filter characteristics. Normal rejection
is used for CDMA and EVDO service.
• Frequency information is available as a reference for setting the center frequency and
band width (refer to section 7).
