INSTALLATION PROCEDURE
UNPACKING
Please inspect all material thoroughly upon arrival. Axcera certifies that upon leaving our facility the
equipment was undamaged and in proper working order. The shipping container should be inspected for
obvious damage indicative of rough handling.
Remove the unit(s) from the shipping container and inspect for damage. Check for dents, and scratches, or a
broken switch, meter or connector. Remove the top cover of the unit and again inspect for shipping damage.
Extract all packing material from inside and around the unit. Check for loose hardware and connectors,
retighten if needed. Any claims against in-transit damage should be directed to the carrier. Save all packing
material in case it is needed in the future.
INSTALLATION OF TRAY(S)
í
Units are shipped with chassis slides mounted to the each side. Included in the Installation Material Kit
are two cabinet mount slide assemblies that will be mounted in the rack. Install the Tray slides into the
cabinet. Refer to the "Cabinet Mounting Instructions Slides Drawing" which follows, for detailed
instructions.
í
Slide the unit into the cabinet. If it does not slide in and out smoothly, some adjustment is necessary.
Pull out the unit (only enough for clearance) and loosen the hardware holding the cable slides to the
cabinet. Move the front of the Tray up or down or side to side to remove the rubbing. Retighten the
hardware after the adjustment is complete.
í
Also included with the unit is a cable retractor assembly, which consists of two parts, a cabinet mount
retractor and a tray mount retractor.
n The cabinet mount retractor has a long aluminum channel hinged to a mounting piece with two bolts.
This is mounted to the rear of the left hand, facing the front of the unit, cabinet mount slide assembly.
n The retractor is a short aluminum channel hinged to a slide mount. This piece slides into a receptacle
mounted to the rear panel of the unit.
These cable retractors work together to move the wire harness and coaxial cables in and out with the movement
of the unit to avoid pinched wires.
í
After the units(s) are physically in place, the process of interfacing them into the system begins by
making connections to the back of the units.

CABINET MOUNTING INSTRUCTIONS FOR SLIDES DRAWING
CONNECTIONS
Once all equipment is in place, making connection to the back of the tray (s) is a relatively simple process.
Each wire is clearly marked with a number corresponding to the tray where it connects.
NUMBERING
The numbering system used on wires that connect to the back of the trays is as follows:
FIRST NUMBER - Channel designator
SECOND NUMBER - Connector on back of tray
EXAMPLE: A wire marked 2 10 would go to channel 2 in the group, connector J10
Finally, verify that AC power (J1) is connected to each unit. Once this is complete, proceed to the initial turn
on procedures.
NOTE: All Axcera products are designed for operation with either 115VAC or 208/230 VAC, 50/60 Hz
input. Systems are shipped from the factory properly configured for the standard of the country of destination.

SYSTEM DESCRIPTION
FREQUENCY GENERATOR TRAY
The Frequency Generator tray is configured to control multiple VCXO’s. within the 4 Channel VCXO
assembly. The selected VCXO output is sent to the VHF Buffer/Combiner Board where the RF signal is
amplified. The output of the VHF Buffer/Combiner Board is multiplied by four and filtered, then processed
by the PLL Board. Once again the signal is multiplied and filtered producing an L.O. output to the agile
upconverter. A liquid crystal display on the front panel provides access to various menus through the use of
five soft touch keys.
10-WATT AGILE UPCONVERTER/AMPLIFIER
The 10-Watt Agile Upconverter/Amplifier accepts an input signal of +25 to +35 dBmV and is compatible
with any QAM signal up to 256 and VSB up to 16. Operating frequency range is from 2572-2614 MHz.
The signal is processed through the unit in a similar manner to that of an analog system with IF circuitry
performing ALC, frequency response and delay correction as well as linearity correction. The RF signal is
sampled, peak detected, and fed to a control amplifier before being connected to the output of the tray.
INITIAL TURN ON
5543A DIGITAL AGILE

MAINTENANCE
PROPER CARE OF THE SYSTEM
This product is designed with components that require no periodic maintenance except for cleaning and record
keeping.
The amount of cleaning necessary depends greatly on the conditions in the transmitter room. While the
electronics have been designed to function well even if covered with dust, heavy buildups of dirt and insects will
impede the effectiveness of the cooling and lead to shutdown or premature failure.
When it is apparent that the front panel is becoming dust covered, the top cover should be opened and the
accumulated foreign material removed. A small, soft brush used in conjunction with a plastic wand-like
attachment on a small vacuum cleaner is an excellent way to suction the dirt out. Alcohol and other cleaning
agents should not be used unless you can be certain that the solvents will not damage components or markings
on the transmitter and boards. Water based cleaners can be used, if only a small amount of moisture is used.
The fans and heatsinks should be cleaned carefully.
Occasionally check that all RF connections are secure, but be careful not to overtighten.
Data should be recorded for all meter readings on a regular basis. It is suggested that data be recorded once
each month and that it be retained in a rugged folder or envelope for the life of the equipment.

ALIGNMENT PROCEDURES
GENERAL:
Due to the complex and delicate nature of this digital equipment, very few adjustments can be made in the
field. Do not attempt to make any adjustments without proper test equipment.
REQUIRED TEST EQUIPMENT
•
•
•
DVM
Frequency Counter
Spectrum Analyzer
For settings other than those covered in this section, a network analyzer and other equipment is
required. If you have any questions on how to adjust your system contact Axcera Customer Service.
OSCILLATOR CALIBRATION:
The FCC requires that the transmitter carrier frequency should be checked once each month. If the carrier is
found to be off frequency, the following procedure should be performed. The data resulting from this
procedure should be logged for future reference. A frequency counter that is capable of 5 x 10-9 stability and a
voltmeter are required.
CALCULATE CENTER CARRIER FREQUENCY.
(FOR FREQUENCY GENERATOR TRAY)
í
Measure the VCXO frequency (f(s)) at the BNC connector on the front
panel (10 digits).
í
Using a 10 digit calculator, perform the following calculation:
[ 16 x f(s)] + 539 MHz
(2nd L.O.) (1st L.O.)
The result should be the desired center carrier frequency, ±500 Hz (Axcera spec.) or ±1000
Hz (FCC spec.)
í In the event the frequency appears to be incorrect, check the agile upconverter
front panel VHF PLL indicator, if it is OFF contact Axcera Customer Service.
