INSTALLATION AND OVERVIEW
General Description
This section describes the installation and theory of operation of the block up converter.
ABC40DC is powered by +36~+60 VDC via IF cable or MS connector.
It will amplify an input signal from an L-Band RF source up to a power level of 40 Watts (min) CW in C-
Band.
The block up converter can be used as a stand-alone unit or in a redundant configuration.
Specifications
Table 1 summarizes the specifications of the ABC40DC BUC. For mechanical specifications, refer to the
outline drawing, Appendix 1.
General Considerations
The block up converter shall meet all specifications over full bandwidth and under all environmental
conditions when terminated with a load of VSWR at 2:1 unless otherwise specified. All RF specifications
shall be met within five minutes after applying power, except gain flatness, which shall be met after a
warm-up period of ten minutes. During the warm-up period, the block up converter shall not exhibit any
alarm or require an RF mute input signal to reset any alarm/fault latches.
Securing the block up converter
Align the block up converter output waveguide flange with the mating flange of the antenna feeder
waveguide. Using the O-ring and hardware provided, connect the antenna feeder waveguide. Torque the
flange screws to 16 inch-pounds (1.8 N-m). Attach the proper cables for waveguide for IF input, AC
power and M&C if equipped to the corresponding connectors of the block up converter.
The cylindrical connectors are labeled clearly and have different pin layouts. It is
impossible to incorrectly install the mating connectors.

Installing the Block-Up Converter
Tools and Test Equipment
Have on hand a standard electrician's tool kit and any tools listed in the antenna
manufacturer's installation instructions.
Site Considerations
The BUC is designed to mount on the antenna. Locate and install the antenna according
to instructions supplied by the antenna manufacturer. Choose an area that is free of
extraneous interference from motors and electrical equipment and has a clear line of sight
from the antenna to the satellite. Lightning arrestors should be used at the site to protect
personnel and equipment.
Preparation
Mounting Considerations:
Optional Mounting Brackets are available that will facilitate mounting for most antennas.
The ODU must be mounted such that:
- Sufficient support is afforded to the BUC, the LNB and the Power supply to minimize
the effects of antenna sway in strong winds.
- Air movement across the heat fins is possible.
- The length of the Power supply cables is taken into consideration in determining the
mounting location of the power supply.
Throughout installation and during any polarization, azimuth or elevation adjustment,
ensure that cables and waveguide are not crimped or pinched.

interference with adjacent satellites or transponders before attempting to align or
performing any other operation involving the ODU. Before attempting any system
change, carefully evaluate the possible effects of the transmitted signal
ABC40DC User Manual
Page 12 of 34
Connections and Mounting Hardware
The IF input connection requires a coaxial cable with an F or N type connector. The RF output requires a
waveguide with a CPR-137G flat flange. An O-ring shall be used to seal the waveguide connection.
Assembly and Installation
Use the information in this section as a guide to assemble and install the block up converter. The
specified humidity is up to 100% during operation. However, installation should be carried out in dry
conditions, free of salt spray or excessive humidity. This will eliminate the possibility of moisture and
other foreign substances from entering the output waveguide flange.
Only authorized technical personnel should perform the Installation and
proper electrical hookups of the block up converter.

Functional Overview
General
This section describes the block up converter functions in detail. The functional overview explains the
RF amplification, monitor & control and power distribution.
IF/RF Conversion and Amplification
The IF Input requires a signal with a 10MHz reference, and 36 - 60 VDC power source. 2-4.5Amps
nominal enters the BUC by a coaxial cable, converted to C-Band by the BUC and goes through an
internal isolator and reject filter, which provides a good VSWR at the input. Under normal operation, the
RF amplifier will amplify the RF Input signal level up to a power level of 46 dBm or 40 Watts CW
minimum.
To achieve the rated output power of the RF Amplifier, provide the necessary gain and low insertion loss.
The amplified signal is transmitted through the output waveguide section to a satellite up-link system.
Monitor and Control (optional)
The block up converter may have a RS-485 and RS-232 serial interface. With this option the block up
converter can communicate to the indoor unit or redundancy control block up converter via RS-485 or
RS-232.
The control system can provide the following M&C functions:
BUC Alarm (via RS-485/RS-232): when an input BUC within the block up converter system
current draw is below 0.3A, a BUC alarm signal will be transmitted via the RS-485/RS-232 serial
interface.
Mute Control (via RS-485/RS-232)
Mute Control (via hardware line): TTL high level signal will mute a block up converter
Output Power Monitoring: 20 dB dynamic range (via RS-485/RS-232)
Base Plate Temperature Monitoring (via RS-485/RS-232)

Operation
It shall be performed by authorized personnel prior to maintenance and/or repair.
Procedure
Verify that the installation procedure described was completed. A complete physical check of the
customer’s system is suggested.
The output power available at the output waveguide flange is extremely
hazardous. Under no circumstances should block up converter be
operated without the waveguide feed or a high power load attached. Do
not operate this equipment in the presence of flammable gases or fumes.
Failure to observe this precaution will result in personal injury. Safe
and careful installation of this block up converter will eliminate the
possibility of accidents and provide years of top performance.
Verify the antenna feed waveguide connection is properly done before the block up converter is
energized.
The block up converter can withstand any source or load VSWR.
However, the block up converter will meet all specification requirements
only if the source/load VSWR is sufficient. Normal operation is not
possible if the antenna feeder VSWR is greater than 2:1.
Turn ON the power and allow a warm up period of twenty minutes before operating the block up
converter. This will assure stable gain and power. The block up converter can function with a coupler
when a direct measurement of the output power is made.

Performance Check
Verify the system is properly set up.
It is recommended to measure the following parameters for ensuring that the block up converter is in
good working condition:
-Gain and Gain flatness
-RF load VSWR and RF source VSWR
-Two-Tone Inter-modulation Distortion
-Return Loss at connectors of the block up converter
Using a Source and an IF input signal level within the small signal region of the block up converter,
measure the power level at connectors IF or MS connector. Plot the swept response on a test data sheet.
From the plot, determine gain and gain flatness.
Plot the swept return loss for both the IF Input and RF Output signals on a test data sheet. From the plot
determine the return loss.
From the output power measurements determine rated output power. Record value on a test data sheet.
Measure the Two-tone Inter-modulation Suppression using two equal signals separated by 5 MHz.
Record value on test data sheet.
Cable connection and disconnection shall be done carefully to avoid
physical damage to the cables and connectors, which may cause
intermittent problems in the future.
A non-warranty and out-of-warranty repair service is available from Actox Corporation for a nominal
charge. The customer is responsible for paying the cost of shipping the BUC both to and from Actox
