Section 4: L-Band Operation 4.0 Block Up Converter Overview The Mini Compact Outdoor SSPA is available with various converter options, utilizing Paradise Datacom’s integrated converter. The primary up converter option is offered in two C-Band configurations, two Ku-Band options, and one X-Band model. The BUC offers ultra low phase noise for applications where phase noise is an overriding factor. For specifications, see Table 4-1.
Block Up Converter Module SSPA Module 55 - 75 dB Gain L Band Input DeMux Reference Input Optional FSK Phase Locked Local Oscillator Optional Internal Reference FSK Optional FSK Monitor & Control Figure 4-2: Compact Outdoor Block Diagram of BUC / SSPA System Note: Unless the BUC has the built-in internal reference option, if there is an absence of a 10 MHz reference signal on the IFL input there will be no output signal from the SSPA. 4.
4.2 Theory of Operation The low gain block up converter has a P1dB of 0dBm. This topology allows the system to be integrated with little impact on the general electrical specifications of the SSPA module. The converter utilizes single up conversion from L-Band to the desired RF band. The local oscillator circuits are designed to maintain the lowest possible output phase noise.
Notes: 1) The external reference option requires the system operator to provide system reference to the BUC/SSPB. The system will not lock and will have no output without external reference applied. 2) Internal reference option allows for either internal or external reference operation.

Section 5: Performance Tests 5.0 Introduction This section describes some of the tests performed on production amplifiers before shipment. Where possible, Paradise Datacom LLC maintains computer automated RF test stations to ensure a high level of accuracy and consistency to production amplifier testing. 5.1 Standard tests All Paradise Datacom Compact Outdoor amplifiers must meet rigid specifications and undergo the following tests.
5.1.2 Spurious Spurious signals are undesirable byproducts of amplifiers caused by nonlinearities within the amplifier and other system level components such as switch mode power supplies. These unwanted signals cause signal management problems in system applications. Out of band spurious signals cause interference to other pieces of equipment. See Figure 5-1, Item [2]. 5.1.3 Input Return Loss The input return loss is measured in all production amplifiers.
5.1.5 Intermodulation Distortion Intermodulation distortion is one of the most important characteristics of a Solid State power amplifier system. Satellite communication systems must comply to certain distortion levels depending on the service involved. All production amplifiers are subjected to automated intermod testing. This is based on a standard two-tone intermod test in which the intermod level (IMD) is measured in dBc with respect to the main tones and the highest third order intermod products.
5.1.7 Earth Ground This test measures the leakage current and verifies that each pin on J8 is connected correctly. See Figure 5-3, Item [1]. 5.1.8 Sample Port The RF Sample Port is measured at discrete frequencies across the band and a calibration label is placed near the Type N connector on the bottom of the unit. The sample port is approximately -40 dB from the RF output level. A label with the exact coupling ratio is attached to the amplifier chassis. See Figure 5-3, Item [2]. 5.1.
5.2 Tests for units with integrated BUC If the Compact Outdoor amplifier includes a block up converter (BUC), the following tests are included. 5.2.1 Reference Lock This test checks the external/internal references (if equipped), as well as lowest locking level at 10 MHz. See Figure 5-3, Item [5]. 5.2.2 FSK Verifies FSK communication with the BUC. See Figure 5-3, Item [6]. 5.2.3 Phase Noise Tests phase noise using external and internal (if equipped) references.
5.3 Optional Tests The following tests are performed on units at the request of the customer, usually to verify specific customer requirements. 5.3.1 Noise Figure Using a noise figure meter, the unit is tested to verify it operates within specification. 5.3.2 Group Delay The testing software measures the linear, parabolic, and ripple components to verify the unit is within specification. 5.3.3 AM/PM The testing software measures the slope of the amplifier’s insertion phase vs. output power. 5.3.
Section 6: Maintenance and Troubleshooting 6.0 Introduction This section describes some of the standard maintenance practices that can be performed on the Mini Compact Outdoor Amplifier and tips to troubleshoot common customer issues. 6.1 Cooling System Maintenance It is recommended that the cooling system be checked at least once per month. This involves visually inspecting the fan intakes to make sure that there is no obstructions over the intake.
6.3 Troubleshooting guide The following section describes solutions for some of the most common issues with the operation of the Mini Compact Outdoor SSPA. 6.3.1 Unit doesn’t power up Cooling fans do not spin, and alarm LED lamps are off. Possible causes: AC power is off; Unit is connected to an inadequate circuit breaker. Unit has no connection between chassis and earth ground or has inadequate earth ground. Possible solutions: Check SSPA unit datasheet for AC power requirements.
Possible solutions: a) In the case where SSPA communication settings have been accidentally set to a random configuration, establish a connection to the unit with a L207755 Quick Start cable in conjunction with the Universal M&C software (see Section 3.2.2.2).

Section 7: Redundant System Configurations 7.0 Redundant System Concepts The Mini Compact Outdoor Amplifier is capable of operating in a variety of redundant system configurations. These include 1:1 and 1:2 as well as 1:1 with L-Band Block Up Converters. The Mini Compact Outdoor Amplifier has a built-in 1:1 redundancy controller, allowing it to be used in 1:1 redundant systems without a separate external controller. When used in a 1:2 redundant system a separate RCP2-1200 controller is required. 7.
The system shown in Figure 7-3 uses the same concept of the power splitter on the RF input. In this case the Compact Outdoor amplifiers are equipped with L-Band block up converters. L-Band input amplifiers use phase locked oscillators as the local oscillator to the up converter. Such systems must use a splitter at the input instead of a switch so that the reference input is always available to the standby amplifier.
Section 8: Remote Control Interface 8.0 Serial Protocol Overview The Mini Compact Outdoor SSPA can be managed and controlled over a variety of remote control interfaces (see Figure 8-1). Remote control interface stack 10Base-T IP Interface SNMP HTTP Web UDP Serial Interface Protocols: 1. Normal 2.
The selected interface is controlled by a combination of internal SSPA settings and/or Interface control pins: Baud1 (Pin e) and Baud0 (Pin j) on the J4 M&C connector (See Table 8-1). Table 8-1: Interface Selection Baud0 (Pin j) state Baud1 (Pin e) state Selected interface Open Open Interface selected by Internal SSPA settings Closure to Chassis ground Open Interface is forced to Ethernet interface. IP address is fixed to 192.168.0.9.
8.1 Serial communication This section describes the normal communication protocol between the Mini CO SSPA and a host computer over RS232/RS485 serial interface. Serial port settings on the host computer must be configured for 8 bit data at no parity, with 1 stop bit. The baud rate should match the selected baud rate parameter on the SSPA unit. Selection between the RS232 and RS485 interface depends on the state of pin D of the J4 M&C connector. Connect pins D and d to select RS232 interface.
8.1.1.3 Source Address The source address specifies the address of the node that is sending the packet. All unique addresses, except the broadcast address, are equal and can be assigned to individual units. The host computer must also have a unique network address. 8.1.2 Data Packet The data sub-packet is comprised of 6 to 32 bytes of information. It is further divided into seven fields as shown in Figure 8-4. The first six fields comprise the command preamble while the last field is the actual data.
varies by the amount of attached data bytes. It may contain 11+N bytes where N is the amount of requested data bytes from a particular table, specified in Data Length field. The Set Request command allows the sender to actively change parameters for the receiver’s internal configuration. The Set Request frame must contain a number of bytes in the Data Field as specified in Data length field. The frame size must be 11+N bytes, where N is the length of the attached data structure.
8.1.2.5 Data Address / Error Status / Local Port Frame Length This field is a tag extension byte and specifies the first table element of the tagged data. If the Data Length is more than 1 byte, then all subsequent data fields must be accessed starting from the specified address. For example, if the requestor wants to access the amplifier’s unique network address, it should set data tag 0 (System settings tag) and data address 8 (see System Settings Details table).
8.1.3 Trailer Packet The trailer component contains only one byte called the Frame Check Sequence. This field provides a checksum during packet transmission. See Figure 8-5. HEADER (4 bytes) DATA (6-32 bytes) TRAILER (1 byte) Frame Check Checksum (1 byte) Figure 8-5: Trailer Sub-Packet 8.1.3.1 Frame Check This value is computed as a function of the content of the destination address, source address and all Command Data Substructure bytes.

8.2 Ethernet Interface 8.2.1 Overview The Mini CO SSPA supports several IP network protocols to provide a full featured remote M&C interface over an Ethernet LAN: • • IPNet protocol – redirection of standard Paradise Datacom LLC serial protocol over UDP transport layer protocol. This protocol is fully supported in Paradise Datacom’s Universal M&C software. SNMPv1 protocol - protocol intended for integration into large corporate NMS architectures.
low overhead resulting in minimal impact to network performance. The control application sends a UDP request to SSPA unit and waits for response. The length of time the control application waits depends on how it is configured. If the timeout is reached and the control application has not heard back from the agent, it assumes the packet was lost and retransmits the request. The number of the retransmissions is user configurable.
8.2.2.2 Setting IPNet interface To set up the Compact Outdoor SSPA with custom IP parameters, the internal IP settings need to be modified by using Paradise Datacom’s Universal M&C, version 4.4.3 or later. See Section 3.3.3. 8.2.2.3 Troubleshooting IP connectivity Check IP connectivity to the SSPA unit. To do so on a Windows-based PC, open a Command Prompt window and type the following command: PING 192.168.0.9, then press the Enter key.
8.2.3 SNMP interface SNMP-based management was initially targeted for TCP/IP routers and hosts. However, the SNMP-based management approach is inherently generic so that it can be used to manage many types of systems. This approach has become increasingly popular for remote management and control solutions for various SSPA systems. Paradise Datacom devices with Ethernet interface support the most popular SNMPv1 format (SMIv1, RFC1155), SNMP Get, SNMP GetNext and SNMP Set commands.
