2.2.1.1 Frequency Synthesizers

The LO signals for the Upconverter and the Downconverter are generated by the fixed and agile frequency PLL (Phase-Locked-Loop) synthesizers. These PLL synthesizers are referenced to a highly stable and low phase noise 10 MHz oven controlled crystal oscillator that is factory tuned to 0.01 ppm. The 10 MHz signal is also used as reference for the PLO in the BUC and the PLLNB. The OCXO can be also fine-tuned via the tuning screw to compensate for normal ageing effects. The frequency produced by the agile synthesizers can be adjusted by the user friendly M & C software. The agile synthesizer provides selection of transmit and receive frequencies in 1.0 MHz (or 1.25MHz) steps over the 500 MHz band, giving 500 channel (or 400 channel) selections.

2.2.1.2 Upconverter

The upconverter converts the 70MHz (or 140MHz) signal input from the 50Ω N-Type connector to the L-Band signal (950-1450MHz). The L-Band output is fed to the BUC via the SMA connector for final conversion to Ku-Band frequency. Double conversion is employed in this upconverter using a fixed LO of 900MHz (or 970MHz for 140MHz IF input) and an agile LO tuneable from 1780MHz to 2280MHz.

There is a variable digital attenuator in the upconversion path for the user to control the gain. This can be done using the M&C software and are in steps of 0.5dB over a 20dB adjustment range. The gain is also automatically controlled to compensate for temperature effects.

2.2.1.3 Downconverter

The downconverter module takes in the L-Band signal (900-1450MHz or 900-1700MHz depending on the LNB being used) from the LNB and downconverts to 70MHz (or 140MHz). Double conversion is employed with the fixed LO at 900MHz (or 970MHz) and agile LO at 1730MHz to 2280MHz.

The user can easily vary the gain in steps of 1dB over a 20dB range using the M&C software. 2.2.1.4 Monitor & Control (M&C)

A user-friendly Monitor and Control software is provided to enable the user to programme

and configure the ODU. The M&C is designed with user friendly GUI (Graphical User Interface) enabling quick deployment and operation of system.

The M&C software permits the AAV628 to be controlled locally or remotely, i.e. either

using a local terminal such as a computer or using a remote terminal connected via an external 4800/9600 baud telephone modem.



The M&C module is as the central processing hub of the ODU system. It is developed on an embedded microcontroller to achieve the monitor and control functions. It allows the monitoring of the system alarms, transmit power levels, gain etc. It can also be used to control the transmit and receive frequencies and attenuation levels. All the configuration parameters are maintained in EEPROM, which provides for total recovery after a power-down situation.

The AAV628 SPT may be connected directly to an RS-232 cable using the dual shielded twisted pair wire. The distance between the transceiver and the computer interface terminal can be up to 30 meters for the RS232 interface, whereas for the RS485 it can be up to 2 kilometres.

2.2.2 Power and Block-Up (PBU) Module

The PBU contains the Block-Up Converter, Solid State Power Amplifier and Power Supply board.

2.2.2.1 Power Supply Board

The power supply is designed to convert the AC power to the DC power required for the various modules of the AAV 628 ODU system. The AC supply is connected to a 3-pin circular connector and is transient protected to suppress power surges. It then passes to a line filter to prevent EMI. The conditioned AC is then rectified and smoothened before being converted to the various DC voltages. The voltages are further regulated at the various modules to ensure isolation and stability.

2.2.2.2 Block Up Converter (BUC)

The BUC serves to upconvert the L-Band signals generated from the upconverter to

Ku-Band signals. A fixed LO of 13.05GHz or 12.8 GHz is used for this purpose. This LO is obtained by a x3 multiplier applied on a PLO of 4.35GHz or 4.26 GHz. The Ku-Band signal is filtered to remove the unwanted mixed frequency products.

2.2.2.3 Solid State Power Amplifier (SSPA)

The AAV628 transceivers are available in different SSPA configurations : 2W, 4W and

8W. All the SSPA configurations are designed on TLY-5 boards bonded onto aluminium baseplates blocks. The SSPA aluminium backed assembly is firmly secured to the housing heat sink to ensure excellent thermal conductivity.

The SSPA receives the KU-BAND signals from the BUC and amplifies them to the

correct power level. This is achieved by multiple gain stages using high performance microwave power GaAs FETs and MMICs. All the FETs are housed in different partitions so as to eliminate any interference from the DC supplies and the other gain stages. The input of the SSPA is protected from any mismatch with internal isolators.



2.2.3 Description of Mechanical Housing

The housing consist of two sections; the top section houses the L-Band module and the bottom section houses the BUC, SSPA and DC board. The housing is designed to be fully weatherproof. The thermal radiative fins are integrated to the bottom section of the housing thus ensuring excellent thermal heat dissipation. The housing has been designed to allow the customer to install the SPT onto the Antenna without any difficulty. The WR75 interface permits the SPT to be directly mounted on the OMT, thereby reducing power loss.

2.3 DESCRIPTION OF THE EXTERNAL REFERENCE PLLNB The external reference PLLNB receives very weak Ku-Band down link signals from the antenna and amplifies them before mixing them down to achieve the required L-Band.

2.3.1 Receive Options Different receive frequency configurations are available to cater for the different Ku-Band transponders :

Region Receive I (Europe, M. East, Africa) 10.95 to 11.70 GHz 11.20 to 11.70 GHz II (Americas) 11.70 to 12.20 GHz III (India, Asia Pacific) 12.25 to 12.75 GHz

2.3.2 Design

The PLLNB uses HEMT (High Electron Mobility Transistor) devices to achieve low noise, high gain and low distortion amplification features. The noise temperature of the PLLNB is less than 105 Kelvin, and gives a gain of 55 to 60 dB. It consists of multiple stages of low noise HEMT devices and a down conversion stage. The external reference signal is at 10 MHz. The block diagram is shown in Figure 2-2.

Figure 2-2 : Block Diagram of PLLNB

RF OutDC & 10MHz In

WG75NType



The N-Type connector not only relays the L-Band signals to the SPT but it also carries the 10MHz external reference signal and 12V DC power, both of which are supplied by the SPT.

The PLLNB is housed in an aluminium housing that is weather proof for outdoor applications. A WR75-G waveguide flange, which is an integral part of the housing, is used for the RF input from the OMT. For water proofing, a gasket is used between the PLLNB waveguide and the OMT waveguide.

2.4 DESCRIPTION OF BOOSTER

The main function of booster is to boost up the transmit power of the signal from SPT. There are two modules inside the booster: Power Supply Board and SSPA.

2.4.1 Power Supply

The power supply is designed to convert the AC power to the DC power required for SSPA module. The AC supply is connected to a 3-pin circular connector and is transient protected to suppress power surges. It then passes to a line filter to prevent EMI. The conditioned AC is then rectified and smoothened before being converted and regulated to the various DC voltages for the gain and power stages of the SSPA.

2.4.2 SSPA The SSPA receives the RF power from the SPT and amplifies it to the correct power level. This is achieved by multiple gain stages using high performance microwave power GaAs FETs. All the FETs are housed in different partitions so as to eliminate any interference from the DC supplies and the other gain stages.

5.7 PRE-INSTALLATION TEST A strong impact during shipment could cause damage to the ODU. Therefore, it is always a good practice to setup the whole system for testing prior to field installation. This is to ensure that there are no damages inflicted on the unit during the shipment.

Following are the test procedures for the ODU system. There are mainly two main tests that are recommended; namely the uplink and downlink tests: Before performing any test, ensure that no alarm appear at the SPT.

5.7.1 Alarm of the SPT

An LED indicator alarm is located in at the front panel of the SPT. The alarm status can be identified according to the Table descriptions of the LED status are as follows in Table 4-4.



5.7.2 Uplink Test Procedure

To avoid damaging the SPT accidentally, connect a 30 dB, > 20W power attenuator to the waveguide output.

Step 1 Connect the SPT as shown in Figure 5-1 and power up the system. For connections to the Booster please refer to Figure 5-2.

Step 2 Use the M&C software to set the desired channel. Refer to Chapter 6 for

operation. Step 3 Use the modem to input a 70 MHz pure carrier (by turning on the transmit

carrier and set the pure carrier feature to ON). Adjust the modem output power so that the IF level input to SPT is -30 dBm. If necessary, use a power attenuator to achieve the correct RF output power.

Step 4 Measure the RF OUT of the SPT by a spectrum analyzer at Ku-Band.

Calculate the transmit gain by subtracting the input power from the output power plus the amount of attenuation included in this link. Compare the gain obtained with the specifications. If there is no signal, check if the channel setting is correct.

Example :

Step 5 Adjust the desired transmit gain level using the M&C software.

Figure 5-1 : Uplink Test Setup (SPT)

!WARNING

Transmit gain = RF OUT power - IF IN power + Attenuation. = -9 - (-30) + 30 = 51 dB [ Example: RF OUT = -6 dBm, IF IN = -30 dBm for 8 W SPT ]



Figure 5-2 : Uplink Test Setup (Booster)

Do not accidentally short the RF Out connector as RF power exists at this output

5.7.3 Downlink Test Procedure

Step 1 Connect a waveguide adapter to the PLLNB and connect the RF out of the PLLNB to the RF IN of the SPT as shown in Figure 5-3. Power up the system.

Step 2 Set channel setting using the M&C software. Refer to Chapter 6. Step 3 Input a -90 dBm Ku-Band continuous wave signal to the PLLNB via the

waveguide adapter at the receive frequency set at the SPT. Step 4 Measure the IF OUT of the SPT by a spectrum analyzer at 70 MHz. (Set the

Spectrum Analyzer to 100 kHz span). Calculate the receive gain by subtracting the input power the from the output power. Compare the gain obtained with the specifications. The typical gain is 25 ∼ 30dB.

Step 5 Adjust to the desired receive gain level using the M&C software.

!WARNING

Do not accidentally short the RF IN connector as DC Power exists at this connector.

5.8 SITE CONSIDERATIONS The VSAT ODU is designed to be installed onto antenna. According to the instructions supplied by the antenna manufacturer, locate and install the antenna in an area that is free from Radio Frequency Interference from motors and electronic equipment. A clear line of sight from the antenna to the satellite is essential. To ensure safety and protection of personnel and equipment, lightning arresters should also be used at the site. Size 3/0 or 4/0 stranded copper wire should be used to bond SPT, LNB and Booster to the antenna frame and to lightning protection ground rod. The grounding resistance of the antenna should not be more than 10 ohms. 5.9 MOUNTING The antenna must have sufficient support to minimise sway in strong wind with the VSAT ODU mounted. It must also allow air movement across the heatsink fins. When mounting the terminal, allow enough space to adjust azimuth and elevation of the antenna and to handle the cables. Note: The length of the interconnecting cables must be taken into consideration in determining the mounting location of the various units.

!WARNING



5.9.1 Mounting of the PLLNB The PLLNB is designed to be mounted onto the waveguide flange of the transmit rejection

filter. The weather gasket must be installed to prevent any water leaks through the waveguide joint. The waveguide flanges are then connected together by screws. The mounting of the PLLNB is shown in Fig 3-4.

Figure 5-4 : Mounting of PLLNB

5.9.2 Mounting of the SPT The ODU is designed to be mounted on both offset and Prime Focus antenna. A set of

mounting accessories is provided to mount the SPT to the offset arm or the base of the antenna. A flexible waveguide extension is run from the SPT RF OUT to the band pass filter which in turn is connected to the WR 75 transmit port of the OMT. The PLLNB is fixed to the Transmit reject filter at the receive port and a cable is run from the PLLNB to the RFIN of the SPT.

Figure 5-5 and 5-6 illustrate the mounting position of the SPT, PLLNB, bandpass filter

and Transmit reject Filter on the offset and Prime focus antennas respectively. The mounting of the SPT ( 2W, 4W and 8W) are illustrated in Figure 5-7 and 5-8 respectively. For the boosters the mounting diagrams are in Figures 5-9 and 5-10.

5.10 CABLING REQUIREMENTS Do not cut any cables provided by Agilis Communications Technologies. The cable lengths are specified in the packing list. Longer or shorter cables are available as options. Low loss RG8 cables should be used for the IFL (Inter Facility Link). Low voltage 8-core computer cable can be used for Monitoring & Control. A single-phase 3-core cable can be used for the AC input. It is recommended to run a spare IFL as a back up. 5.11 POWER REQUIREMENTS The VSAT AAV628 requires a power source that supplies 220-230 VAC or 110 VAC (optional) at 50-60 Hz. To ensure uninterrupted service, an uninterrupted power supply (UPS) is recommended. It is strongly recommended to install surge arresters at the AC line to obtain a stable AC supply by reducing current and voltage surges and hence to ensure smooth operation of the SPT. Ensure that the surge arrester is grounded. Note: AC transients and surges can cause data transmission errors and loss of synchronisation in the modem and/or in the agile synthesizer.

5.11.1 Mounting of Transient Protection Box

The transient protection box is installed close to the SPT. The AC cable length from the Surge protector to the SPT not exceed one meter. It is essential that the protector be earthed. The AC output from the protector should never be routed close to the AC input line or the earth stud. The interconnection method is shown in Figure 5-11. For those remote areas where the AC power supply is not stable, an isolate transformer should be implemented to prevent damaging the SPT.



Figure 5-11 : Connection for the Transient Protection Box 5.11.2 Earthing It is essential that the protector be connected to earth. If the protector is being installed onto a supply without the earth conductor (e.g. : double insulated) the protector must be connected to the local power via the M6 stud provided as shown in Figure 5-12.

Figure 5-12 : Connection for the transient protection box 5.11.3 Keep clean lines away from dirty lines To ensure that the transient protection box is working effectively it is essential that the clean outgoing lines are routed away from the dirty incoming lines or the dirty earth leads (or cross bonds) as illustrated in Figure 5-13.

(a) (b) Figure 5-13 : Wrong Connection



Figure 5-14 illustrates the proper illustration of the transient protection box to ensure clean power supply

Figure 5-14 : Correct Connection 5.12 CONNECTIONS

5.12.1 Grounding

Electrical bonding (grounding) of the SPT is recommended to prevent possible damage from lightning and/or other induced electrical surges. To ensure safety and protection of personnel and equipment, lightning arresters should also be used at the site. Size 3/0 or 4/0 stranded copper wire should be used to bond power supplies of the ODU equipment to the antenna frame and to lightning protection ground rod.

5.12.2 Interconnection Diagram

Connect up the modules according to the interconnection diagram of VSAT ODU shown in Figure 5-15 and Figure 5-16 for the SPT and Booster respectively.

Figure 5-15 : Interconnection Diagram of SPT



Figure 5-16 : Interconnection Diagram of SPT and Booster

5.13 SEALING To complete an installation, seal up all the connectors and wave guide joints of the system using self-amalgamating tape. It is recommended all “sealing job” should be done after the system has verified operational. The following points should be taken care of: 1. Make sure that all the connectors are hand-tightened before sealing. 2. The sealing must cover from the housing of the SPT until after the heatshrink sleeve.

Refer the Figure 5-17 for the sealing. 3. All the unused connectors must be covered with a cap and sealed. 4. Make sure all waveguide joints are properly sealed with an appropriate gasket.

Chapter 7 : Maintenance 7-1 AAV628 Ku-Band SPT Rev E

CHAPTER 7 MAINTENANCE 7.1 GENERAL This chapter describes how to perform periodic maintenance on the AAV628 Ku-Band VSAT SPT. It is recommended to carry out the maintenance service at least twice a year to ensure the performance of the system. It is recommended to maintain a SETUP RECORD that contains the modem and SPT configurations, power levels of the carriers at various points of the link and the system power level diagram when the system was set up. Make sure that this record is updated every time when any changes are made. Make sure that the system can be interrupted for approximately two hours before starting the maintenance. It is advised to understand the procedure and prepare necessary equipment before starting the service. 7.2 MAINTENANCE PROCEDURE

7.2.1 Gain Testing

The following procedure is to be carried out to check the up and down link gains of the SPT. At indoor,

Step 1 Confirm that the demodulator is locked to the receive signal (by looking at the DEMODULATOR LOCK indicator at the modem ) and that no alarm is indicated.

Step 2 Check if the transmit and receive configuration of the modem and SPT

configuration comply with the SETUP RECORD. Contact the responsible personnel in case of any discrepancies.

Step 3 Turn on the pure carrier of the modem and measure the power level using a

spectrum analyzer.

Step 4 Measure the indoor AC power supply. If the AC power supply varies beyond the limits highlighted in Table 7-1, then an Automatic Voltage Regulator between the AC power supply and the equipment is required.



Tolerance for 220-230Vac 50Hz

Tolerance for 110Vac 60Hz

Line – Neutral 220-230Vac ± 10% 110Vac ± 10% Line – Earth 220-230Vac ± 10% 110Vac ± 10% Neutral – Earth < 5Vac < 5Vac

Table 7-1 : AC Power Supply Tolerances

At outdoor,

Step 4 Ensure that all the IF and RF cables are labelled.

Step 5 Make sure that all the cables are in good condition using the mega ohm meter. Ensure that the cables are removed at both ends before the measurements are taken. Check visually if the connectors are not damaged.

Cable connection and disconnection should be done properly to avoid damage to the cables or connectors that may cause intermittent problems in the future.

Step 6 Measure the outdoor AC power supply. The reading of the AC power supply should not exceed the values stated in Table 7-1 otherwise an Automatic Voltage Regulator between the AC power supply and the equipment is required.

Step 7 Measure the ground resistance of the antenna with a mega ohm meter. The

reading should not be more than 10 ohms.

Step 8 Connect back the transmit cable to the modem and measure the power level of the pure carrier to the SPT input. Calculate the transmit IFL loss and check if it is close to that at the SETUP RECORD.

Power off the SPT and connect a power attenuator (30 dB, >20W) with WR75 to N adapter at the RF OUT of the SPT.

Step 9 Turn on the SPT and connect the IF IN cable to the SPT. Record the RF OUT power level and calculate the uplink gain. Check if it complies with the SETUP RECORD and SPT gain setting.

Step 10 Connect back the waveguide to the RF OUT. Ensure that the waveguide is

properly sealed with an appropriate rubber gasket.

!CAUTION

!CAUTION



Step 11 Measure the power level and C/No of the receive carrier under consideration at the SPT IF OUT and make sure that the values are approximately the same as the values in the SETUP RECORD. Contact the transmit site and get the levels confirmed if there is considerable variation in the readings.

Step 12 Measure the level at the modem IF input and calculate the receive IFL loss.

Check the value with that at the SETUP RECORD.

7.2.2 Water Leakage Protection

All the connectors at the outdoor should properly be sealed against water leakage using self-amalgamating tapes. The following is the procedure for the maintenance.

Step 1 Make sure that all the connectors are hand-tightened before sealing.

Step 2 Check and ensure that all the connectors and waveguide joints of the system

are properly sealed using self-amalgamating tape. Re-do the sealing if the existing sealing is not good

Step 3 The sealing must cover from the housing of the SPT until after the heatshrink

sleeve at the cables.

Step 4 All the unused connectors must be covered with caps and sealed. 7.3 FINAL CHECK

Make sure every thing including the equipment settings is normalized after the maintenance. Make sure that the SETUP RECORD is updated if any changes in the configuration are done.
