1 INTRODUCTION
OVERVIEW
7010STC-O3b-A and 7010STC-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 (7010STC-O3b-A:1052-1788 MHz, 7010STC-O3b-B: 972-1871 MHz) to RF signal (7010STCO3b-A: 27.652-28.388 GHz, 7010STC-O3b-B: 28.172-29.071 GHz) with maximum linear output
power of 38dBm and saturated output power of 40dBm.
This manual provides the instructions necessary for operation and maintenance of 7010STC-O3b-A
and -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 RS232 and Ethernet communication interfaces for 7010STC-O3b-A and 7010STC-O3b-B.
FEATURES
7010STC-O3b-A and 7010STC-O3b-B are comprised of IF, LO, Up-Converter, SSPA, and DC M&C

Figure 1. Functional Block Diagram of Ka-band 10W BUC
IF unit
IF unit amplifies the transmission signal from a remote modem and delivers it to the Up-converter
unit.
LO unit
LO unit generates two local signals to drive two LO ports of the up-converter using double
conversion structure.
Up-converter unit
Up-Converter converts the IF signal (7010STC-O3b-A:1052-1788 MHz, 7010STC-O3b-B: 972-1871
MHz) to RF signal (7010STC-O3b-A: 27.652-28.388 GHz, 7010STC-O3b-B: 28.172-29.071 GHz)
and also filters out unwanted spurious and harmonics in front of SSPA. The BUC uses a doubleconversion technology to achieve better performance and cost-effective design.
SSPA unit
The main function of SSPA is to boost up the transmit power of the input signal to an expected level.
The SSPA includes the following modules: Divider, Power Amplifiers, and Combiner.

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 beginning to use the BUC.
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.
Cleaning
Do not use liquid washing products or aerosols. Only use a damp cloth for cleaning.
Water
Do not expose the BUC to standing water. Failure to follow this precaution could result in electric
shock and injury to persons.
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 persons as well as a severe damage to the BUC.
Power Supply
An external power supply is necessary to convert the input AC to +48V DC, and for the internal
DC/DC converter within the BUC to generate appropriate DC voltages for IF, LO, Up-converter,
SSPA, and DC M&C units.

4 INSTALLATION
This section of the manual is intended to provide aid in BUC installation.
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 Intl Inc. or a local representative before
proceeding.
The shipping container and packing materials should be retained for possible reshipment.
Accessories for 7010STC-O3b-A or 7010STC-O3b-B are four waveguide adapter fixing screws, and
an O-ring for the waveguide adapter.
INSTALLATION ON ANTENNA
7010STC-O3b-A and 7010STC-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.

The BUC has body and cover heat sinks with fins for air 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 10W BUC
CABLE INSTALLATION
The connections of 7010STC-O3b must be done using a waveguide (output) and coaxial cables
(input). The length of cables 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.
WATERTIGHT SEALING UP OF CABLES AND CONNECTORS
The application of moisture-resistant tape over the connectors is always recommended in outdoor
installations to ensure an appropriate waterproofing. The application procedure of this tape is the
following:
a) 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.

6 MAINTENANCE AND TROUBLE SHOOTING
MAINTENANCE
Ka band 10W BUC is designed for a minimum of maintenance and does not use fans for cooling.
Instead, it has two heat sinks with lots of air cooling fins on the cover and body of the BUC for
cooling. Therefore, periodic scheduled maintenance is not required. However, make sure that it is
mounted upside down so that fins of the body heat sink are open to fresh air as shown in Fig. 7.
And check periodically that there are no objects that obstruct a flow of fresh air into the fins of the
body heat sink.
TROUBLE SHOOTING
The BUC GUI window shows various status of the BUC such as LO Lock, Over-temperature, Overpower, and External Mute. These states indicate the faults that may arise in the BUC. The BUC is
designed to automatically turn on the SSPA to avoid transmitting unwanted power to the target
satellite if one of LO Lock, Over-temperature, Over-power, and External Mute states becomes red
on BUC GUI window during the operation.
The following explains two major types of faults and how to troubleshoot them.
A) SSPA is off
1) When LO Lock state became red on the BUC GUI window.
- The internal LOs are out of lock.
Check the power level of 10MHz reference source at the modem side or at the BUC
input side.
Otherwise, since the BUC is faulty, contact Norsat for further support.
2) When Over-temperature state became red on the BUC GUI window.
- The BUC is faulty if the BUC is hot
Contact Norsat for further support
- M&C processor is temporally malfunctioning if the BUC is not hot.
Turn off the main power supply of +48V and wait for about 5 minutes, and then turn
on again and check the Over-temperature state on the BUC GUI window.
3) When Over-power became red on the BUC GUI window.
- IF input power is too high
Check the IF input power level.

© 2013 Norsat International Inc. Page 25 of 26
- Or, the BUC is faulty
Contact Norsat for further support.
4) When External Mute became red on the BUC GUI window.
- +5V DC voltage is not applied to the External Mute pin
Check the DC power supply that supplies +5V to the External Mute pin.
- Or, the BUC is faulty
Contact Norsat for further support
B) RF output power is low even if SSPA is on
1) Gain setting on the BUC GUI window is too low
Check gain setting on the BUC GUI.
2) Input IF power is too low to drive the BUC properly
Check the output level of the IF power source.
3) IF cable or connectors has high insertion loss
Check the IF cable or connectors.
4) RF cable or connector or WR28 waveguide adapter has high insertion loss
Check the RF cable, connector, or WR28 waveguide adapter.
5) One of internal components are faulty
Contact Norsat for further support.
