Page 5
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 (A:1052-1788 MHz, B: 972-1871 MHz) to RF signal (A: 27.6 52-
28.388 GHz, 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 cost­effective 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.
The SSPA includes the following modules: Divider, Power Amplifiers, and Combiner.
1.2.5 DC M&C unit This board includes a DC/DC converter, regulators, and an 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 CAUTIONS AND WARNINGS Read all the following instructions prior to using the BUC.

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 Inc. or a local representative before
proceeding.
The shipping container and packing materials should be retained for possible reshipment.
Accessories for 7020STC-O3b A or B are four waveguide adapter fixing screws, and an O-ring for the waveguide adapter.
4.2 INSTALLATION ON ANTENNA
7020STC-O3b 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.
Figure 6. Location of fixing holes on Ka 20W BUC

Page 12
The BUC has body and cover heat sinks with fins as well as a fan 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 and the air opening of the fan are open to fresh air as shown in Fig. 7. Ensure that there are no objects that obstruct the flow of fresh air into the fins of the body heat sink and the air opening of the fan.
Figure 7. Air cooling fins and fan of Ka 20W BUC
4.3 CABLE INSTALLATION
The connections of 7020STC-O3b A or B 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.
4.4 WATERTIGHT SEALING UP OF CABLES AND CONNECTORS 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.

5.2.5 BUC Turn-on/off Sequence. After the user software is installed on your PC, the following sequence can be used to turn on the BUC.
1) Connect one end of a RF cable with a WR28 waveguide adapter to WR28 RF port on the BUC and the other end of the RF cable to the antenna or a dummy load.
2) Connect one end of an IF cable to N-type IF connector on the BUC and the other end of the IF cable to the output of the IF source or modem.
3) Connect one end of a MS 12-wires cable to MS 12-pins connector on the BUC. And connect two wires out of the other end of the MS 12-wires cable, which are dedicated to DC power, to a power supply with +48V DC or a level specified in the specification sheet in Section 3.1, and four wires for Ethernet connection or three wires for RS232 connection out of the other end of the MS 12-wires cable to the modem or your PC, and external Mute wire to a ground. (Refer to Table 1 and Fig. 4 for connection details)
4) Turn on the power supply to supply +48V to the BUC.
5) Set up the serial mode or Ethernet mode connection according to Section 5.2.3 or 5.2.4.
6) Once your PC or modem is connected with the BUC using either serial or Ethernet mode, check various BUC status such as Output power, Temperature, LO Lock, Over-temperature, Over-power, Fan, and external mute.
7) Turn on the IF power source with a proper power level according to the BUC specification sheet, which enters the IF input port of the BUC.
8) To turn on the SSPA, make sure that all of LO Lock, Over-temperature, Over-power, and External Mute states should be green. Then click SSPA ON button on BUC GUI window.

6. MAINTENANCE AND TROUBLE SHOOTING
6.1 MAINTENANCE Ka band 20W BUC has body and cover heat sinks with fins as well as a fan 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 and the air opening of the fan are open to fresh air as shown in Fig. 7. Check periodically that there are no objects obstructing the flow of fresh air into the fins of the body heat sink and the air opening of the fan. And also periodic maintenance to clean the fan dust is required.
6.2 TROUBLE SHOOTING The BUC GUI window shows various status of the BUC such as LO Lock, Over-temperature, Over-
power, 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 hot.
Turn off the main power supply of +48V and wait for about 5 minutes, and then turn
