Introduction CST-5000 C-Band Satellite Terminal

1.1.1 Applications

When used in conjunction with EFData modems, the CST-5000 is ideal for:

• Single digit carriers up to 2.048 Mbit/s

• Multiple carrier operation over a 36 MHz bandwidth

Because the CST-5000 has a 70 MHz IF, it can also be used for other analog and digital applications.

Small to medium size earth stations are easily constructed and commissioned with the CST-5000.

When used with a high-gain antenna, the CST-5000 can also be used as the Radio Frequency (RF) electronics of a central hub in point-to-multipoint applications, as well as serving as the terminal for the end points of a network.

1.1.2 Monitor and Control (M&C)

An on-board microcomputer monitors and controls all operational parameters and system status of the CST-5000. This powerful M&C system enables the user to control functions, locally or remotely, such as:

• Output power

• Transmit/receive channel frequencies

The system also reports terminal configuration status, as well as fault status of all CST-5000 components.

The CST-5000 can be initially configured using the:

• Connection of a common ASCII/EIA-232-C terminal connected to the serial port. A simple command set then allows total configuration control and retrieval of status information.

• Optional keyboard/LCD (Liquid Crystal Display) controller within the enclosure.

If the indoor unit is a more sophisticated station M&C computer, the serial port can be set to EIA-485 for bus operation.

For more information on the M&C board, refer to Chapter 5.

1–4 Rev. 9

CST-5000 C-Band Satellite Terminal Introduction

1.1.3 Low Noise Amplifier (LNA)

The feed assembly consists of an LNA and a wave guide transmit reject filter.

The transmit reject filter provides receive system protection from transmit energy fed back through the antenna feed system.

The LNA standard noise temperature is 65°K, with optional upgrades down to 33°K, depending on gain over temperature (G/T) requirements.

1.1.4 Outdoor Enclosure

The RFT-500 assembly is a weatherproof enclosure housing the following:

• Solid State Power Amplifier (SSPA)

• Up and down converters

• M&C microprocessor

• Power supply and cables, which interface with an antenna subsystem

In the transmit (uplink) direction, the RFT-500 accepts a 70 MHz IF signal, and transmits it in the 5.845 to 6.425 GHz frequency band.

In the receive (downlink) direction, the terminal accepts an RF signal in the 3.620 to

4.200 GHz band, and converts the signal to a 70 MHz IF output.

Power levels range from +8 dBm (for driving an external Traveling Wave Tube (TWT) or amplifier) to 40W, depending on Equivalent Isotropically Radiated Power (EIRP) requirements.

The up and down converters are dual conversion, with individual synthesizers for independent transmit and receive transponder selection.

The microprocessor provides:

• On-line loop monitoring

• Dynamic control functions

• Configuration control

• Fault/status monitoring

• Serial computer/terminal interface

1.2 Options

Contact an EFData marketing representative for more information about the options described in this section.

1.2.1 Configurations

The CST-5000 can be ordered with various configurations, including:

• Output power levels.

• Input power (AC/DC).

• Step sizes. For example, 125 kHz step size. The 125 kHz step size option allows

the transmit and receive frequencies to be adjusted within 125 kHz. The higher resolution step size of 125 kHz requires replacing the synthesizer modules and upgrading the software on the M&C board.

• LNA gain.

• Redundant LNA mounting plates.

• Custom logos.

• Wider bandwidths. The 140 MHz IF option enables the user to double the

available bandwidth. Specifically, instead of the standard 70 MHz, this option allows 140 MHz,

± 36 MHz. For more information, refer to

Appendix A.

• Multi-carrier system. The multi-carrier option allows external separation of the up converter and SSPA for possible multiple carrier inputs. For more information, refer to Appendix A.

2.5.4 RX/RF Input (J4)

The RX/RF input is a type N connector that receives the signal from the LNA. The input impedance is 50

Ω.

The input frequency range is from 3.620 to 4.200 GHz.

The input signal level ranges between -50 and -25 dBm, depending on LNA and antenna gain.

The input level should be set to give the required signal level at J3, the RX/IF Output (refer to Section 2.5.3).

2.5.5 Prime Power (J5)

The AC power is supplied to the RFT by a 3-pin circular connector.

Normal input voltage is 95 to 230 VAC, 47 to 63 Hz.

The AC pinout is as follows:

Pin # Name Function Wire Color

A HI Line Brown

2.5.6 Serial Remote Control (J6)

The remote connector on the RFT is used to interface the M&C functions to a remote location. This interface can be either EIA-232 or EIA-485.

When using an EIA-485 interface, the transmit and receive signals are able to accommodate either type of remote equipment pinouts. As long as the polarities of the remote equipment TX and RX signals are correct, this remote interface will be completely compatible.

Refer to Table 2-3 for a list of pinouts for the J6 connector.

For standard EIA-232 or EIA-485 applications, an adapter cable must be used to connect the 26-pin connector (J6) to a standard 9-pin D.

Refer to Figure 2-5 for an illustration of the adapter cable and pinouts.

THEORY OF OPERATION

This chapter provides the basic theory of operation for the Monitor and Control (M&C) board, high stability oscillator, IFLOs synthesizers, and the up and down converters.

5.1 Monitor and Control

The RFT-500 uses a sophisticated microcontroller module to perform the M&C functions of the terminal. This board (refer to Figure 5-1) is located inside of theRFT-500, on top of the other assemblies.

The M&C monitors the RFT-500 and provides configuration updates to other modules within the terminal when necessary.

Terminal configuration parameters are maintained in EEPROMs, which provides for total recovery after a power-down situation.

Fault monitoring and status gathering are also provided.

All RFT-500 functions are accessible through the local front panel keypad/display or a remote communications interface.

Note: For more information on the M&C board, refer to Chapter 1.

SHU

5.1.1 EEPROM Memory

EEPROM memory on the M&C module allows it to retain configuration information without prime power for at least one year. If the terminal is powered down, the following sequence will be carried out by the M&C microcontroller:

1. When power is reapplied, the microcontroller checks the EEPROM’s Random Access Memory (RAM ) to see if valid data has been retained. If valid data has been retained, the terminal is reconfigured to the configuration maintained in EEPROM.

2. If EEPROM memory fails the valid data test, a default configuration from Read Only Memory (ROM) is loaded into the system.

5.1.2 Remote Interface

The functions of the RFT-500 can be remotely controlled and monitored via an EIA-485 or EIA-232 communications link. The M&C module must be hardware configured to one of the two interfaces.

The EIA-485 interface makes it possible to operate 255 terminals on a common communications link.

The EIA-232 interface is used to communicate with a single terminal.

Refer to Figure 5-2 for the jumper placement at JP3.

On initial power-up, the unit will default to the following parameters:

5.1.4 Theory of Operation

Refer to Figure 5-3 for a functional block diagram of the M&C.

The M&C board performs the following operations:

• Receives the desired frequency from either the remote EIA-232/485 or local keypad, and after converting it to a synthesizer setting, stores it to the applicable synthesizer output latch.

• Reads the thermistors located in the up converter, down converter, and HPA, and converts the signals into temperatures for display.

• Reads the characterization EEPROMs in the up converter, down converter, and HPA, and calculates an Automatic Gain Control (AGC) voltage based on frequency and temperature to linearize the respective module.

• Turns the fan on or off, depending on the temperature.

• Receives fault inputs from all modules, and presents them to the remote

EIA-232/485 and the optional local keypad display.

• Performs an initial current sense on the LNA, and stores the reading in the EEPROM. Subsequent current sense readings are taken and compared to the initial reading to determine a fault.
