1. INTRODUCTION
1.1 OVERVIEW
7005STC-O3B-A and 7005STC-O3B-B are highly reliable and innovative Block Up-converters (BUC)
specially designed for O3B satellite communication uplink system. This equipment converts the IF
signal (7005STC-O3B-A:1052-1788 MHz, 7005STC-O3B-B: 972-1871 MHz) to RF signal (7005STC-
O3B-A: 27.652-28.388 GHz, 7005STC-O3B-B: 28.172-29.071 GHz) with maximum linear output
power of 35dBm and saturated output power of 37dBm.
This manual provides the instructions necessary for operation and maintenance of 7005STC-O3B-A
and 7005STC-O3B-B. All user interfaces present in the BUC, as well as an exact description of the
diverse signals in the connectors of the BUC, will be described in this document. This manual also
explains the RS-232 and Ethernet communication interfaces for 7005STC-O3B-A and 7005STC-
O3B-B.
1.2 GENERAL DESCRIPTION
7005STC-O3B-A and 7005STC-O3B-B are comprised of IF, LO, Up-Converter, SSPA, and DC M&C as
shown Fig. 1.

1.2.1 IF unit
IF unit amplifies the transmission signal from a remote modem and delivers it to the up-converter unit.
1.2.2 LO unit
LO unit generates two local signals to drive two LO ports of the up-converter using double conversion
structure.
1.2.3 Up-converter unit
Up-Converter converts the IF signal (7005STC-O3B-A:1052-1788 MHz, 7005STC-O3B-B: 972-1871 MHz)
to RF signal (7005STC-O3B-A: 27.652-28.388 GHz, 7005STC-O3B-B: 28.172-29.071 GHz) and also
filters out unwanted spurious and harmonics in front of SSPA. The BUC uses a double-conversion
technology to achieve better performance and cost-effective design.
1.2.4 SSPA unit
The main function of SSPA is to boost up the transmit power of the input signal to an expected level.
1.2.5 DC M&C unit
This board includes a DC/DC converter, regulators, and a EMI/EMC filter to make all kinds of DC voltages
required in the BUC. It also contains a Monitor and Control (M&C) function to monitor and control the
BUC, and communicate with a remote modem unit. The key parts for the M&C function are a
microprocessor and communication ICs for RS-232 and Ethernet.
1.3 IMPORTANT PRECAUTIONS
Read all the following instructions prior to using the BUC.
1.3.1 Reading Introduction
There is a potential safety risk unless appropriate precautions are taken while working with the BUC. All
the precaution and danger notes must be carefully read before using the BUC.
1.3.2 ESD Protection
The BUC contains elements sensitive to electrostatic discharges (ESD). It is important that the staff is
ground- connected while they are working with them.
1.3.3 Washing
Do not use liquid washing products or aerosols. Only use a damp cloth for cleaning.
1.3.4 Water and Humidity
Do not expose the BUC to standing water. Failure to follow this precaution could result in electric shock
and injury to persons.

1.3.5 Installation of the BUC
The BUC described in this manual should not be installed in an unstable situation because it may
cause serious injuries to the staff as well as a severe damage to the BUC.
1.3.6 Power Supply
An external power supply is necessary to convert the input AC 230V to +48V DC, and the internal
DC/DC converter within the BUC generates appropriate DC voltages for IF, LO, Up-converter, SSPA,
and DC M&C units.
1.3.7 Equipment Working Conditions
Never perform maintenance or make adjustments to the BUC when the power supply is connected.
1.3.8 Important Safety Information
Read the chapters on Installation and System Operation before attempting to switch on the BUC.
Do not connect the power port to a power source until all the other connections have been made.
Precautions
1.Do not operate the BUC without a cable or a RF load connected to the RF OUTPUT waveguide port.
2.Never look into the waveguide opening when the BUC is powered on.

4.INSTALLATION
This section of the manual is intended to provide aid in BUC installation.
4.1 UNPACKING
Perform an initial inspection upon receiving the BUC. You are advised to ensure the following:
•Check that the shipping container is not opened or damaged.
Have a representative from the shipping company present if you suspect that the
shipment is damaged or tempered with before opening the container.
•Check that all items in the packing list are present and undamaged.
•If any loss or damage is discovered, contact Norsat or a local representative before
proceeding.
•The shipping container and packing materials should be retained for possible reshipment.
Accessories for 7005STC-O3B-A or 7005STC-O3B-B are four waveguide adapter fixing screws,
an O-ring for the waveguide adapter.
4.2 INSTALLATION ON ANTENNA
7005STC-O3B-A and 7005STC-O3B-B have two M4 threaded holes at each side of BUC as shown
in Fig. 6 and these holes are used to fix the mounting bracket when used as stand-alone unit.
Please fix proper brackets to four fixing holes on the BUC before mounting the BUC to the antenna.
One of these fixing holes can be used to connect the BUC housing to the earth for grounding.

The BUC has body and cover heat sinks with lots of air cooling fins for cooling. Therefore, to achieve
an optimal function of the BUC, it should be mounted upside down so that fins of the body heat sink
are open to fresh air as shown in Fig. 7. Ensure that there are no objects that obstruct a flow of fresh
air into the fins of the body heat sink.
Figure 7. Mounting position of Ka band 5W BUC
4.3 CABLE INSTALLATION
The connections of 7005STC-O3B-A or 7005STC-O3B-B must be done through a waveguide or
coaxial cables. The length of them must be adjusted depending on the installation. An inappropriate
choice of the interface waveguide or cable may result in either a reduction of output power at the
external unit or an excessive distortion of the signal.
Some guidelines to install the interface cables between the internal units (Power supply and
Modem) and the external unit (BUC) are as follows:
a) Make a plan with the minimal route to be followed by the cables. It is recommended
that 2m of additional cable is added for ease of maintenance.
b) Secure the cables at each end of the connection.
c) Ensure that the external connectors are waterproof as well as resistant to other agents.
4.4 WATERTIGHT SEALING UP OF CABLES AND CONNECTORS
The application of moisture-resistant tape over all the connectors is always recommended in every
type of outdoor installations because this ensures an appropriate waterproofing. The application
procedure of this tape is the following:
a) The application of moisture-resistant tape over the connectors is always recommended in
outdoor installations to ensure appropriate waterproofing. The application procedure of this
tape is the following: Ensure that all the connectors are correctly tightened. Cut a piece of
moisture-resistant tape with the desired size and remove the protector plastic of the tape.

b) Centre an end of the tape over the connector you want to protect and wrap tape tightly
and evenly over entire connector.
c) Repeat the steps above for all the connectors
5.EQUIPMENT OPERATION
5.1 USER SOFTWARE INSTALLATION
The user software is a Windows based Graphical User Interface (GUI) to monitor and control the
BUC (7005STC-O3B-A). It requires a dedicated LAN port or a PC serial port (COM port) to
communicate with the BUC. If your PC has no serial port, an USB to RS232 adaptor is necessary to
establish the connection (sold separately).
5.1.1 Installation Requirements
The user software installation requires Window XP or later versions with .NET Framework 4.0 pre-
installed on your PC. The following list shows the minimum system requirements for installation:
•PC with an available RS-232 serial communication port
•PC with an available RJ-45 LAN communication port
•Microsoft Windows XP or later versions with .NET Framework 4.0 installed
•1000MHz Processor
•RAM of 1024 MB
•Free hard disk space of at least 10 MB
•Monitor with 1024 x 768 screen resolution

Select a usable COM port and the baud rate of 57,600 and click the open button. If the COM port is
open, BUC GUI will show a serial number (SERIAL NO), and the LED color for SERIAL changes from
red into green and Enable is marked as shown in Figure 13. BUC GUI starts reading status information
of the BUC periodically. And you can send control commands you want to the BUC by clicking proper
tabs such as MAX GAIN or SSPA ON or entering serial commands into the serial command text box
shown in Fig. 13.
