Safety Notice

This equipment has been designed to minimize exposure of personnel to hazards.

The operators and technicians must:

• Know how to work around, with and on high voltage equipment.

• Exercise every precaution to ensure personnel safety.

• Exercise extreme care when working near high voltages.

• Be familiar with the warnings presented in this manual.

CAUTION - A Neutral Fusing - Double pole/ neutral fusing used on the prime power supply input.

Installation Guidelines Regarding Power Line Quality

As a company with many years of experience selling and servicing equipment installed around the world, Comtech EF Data has become familiar with the varying quality of the AC power grid around the world. The following offers some installation guidelines that should help ensure a reliable installation.

• Surge suppression: High voltage surges can cause failure of the power supply. These surges are typically caused by circuit switching on the main AC power grid, erratic generator operation, and by lightning strikes. While the transceiver does have built in surge suppression, if the unit will be installed in a location with questionable power grid quality, Comtech EF Data recommends installation of additional power conditioning/surge suppression at the power junction box.

• Grounding: The transceiver provides a grounding terminal. This is provided to allow the user to ground the transceiver to the antenna’s grounding network. All components installed at the antenna should be grounded to a common grounding point at the antenna.

• Electrical welding: If welding needs to take place at the antenna, disconnect all cables from the transceiver except for the ground wire. Cap all RF connections with terminations. This will prevent damage to the input/output circuitry of the transceiver.

• Lightning: Lightning strikes on or around the antenna will generate extremely high voltages on all cables connected to the transceiver. Depending on the severity of the strike, the transceivers internal surge protection combined with the recommended external suppression may protect the transceivers power supply. However, if the installation will be in an area with a high probability of lightning strikes, Comtech EF Data recommends the installation of surge suppression on the RF and IF cables. One source of these suppressors is PolyPhaser (www.polyphaser.com

For further information, please contact Comtech EF Data, Customer Support Department.

Chapter 1. INTRODUCTION

1.1 INTRODUCTION

This manual provides instructions on the installation, operation and maintenance of the XSAT-7080, 5 to 25, 50, and 100 Watt Model X-Band Transceiver, manufactured by Comtech EF Data, Tempe, Arizona.

1.2 Functional Description

The XSAT70870 is designed for use in communication systems, or in satellite up-link data systems, for the reception of SCPC/MCPC, DAMA, and TDMA communication signals. It can also be used in communications system applications with full transponder HDTV and analog TV.

The converter is environmentally sealed and is designed to be hard mounted on or near the antenna structure. A covered cooling fan is mounted on the outside of the unit to maintain a reduced operating temperature for enhanced reliability.

The Downconverter RF input connector is wired to supply DC voltage to an LNA. This voltage is capable of damaging any test equipment connected to the

connector. Do not connect test equipment to this connector without a coaxial DC block between the connector and the test equipment.

3.2 TURNING ON THE XSAT

The XSAT does not contain a ‘Power On/Off’ switch. The XSAT is powered ON by connecting the J3 “AC Power” connector to the appropriate prime power source. See Section 1 for detailed requirements for the ‘prime power source’.

Never turn the unit ON without proper termination on the J7 “RF OUTPUT” port. Individuals can be exposed to dangerously high

WARN ING

In addition, when directly connecting the XSAT to Laboratory Test Equipment, a DC block should be used between the J2 ‘RF IN’ port and RF test source. The reason for this is that the XSAT can be configured to supply a 12Vdc, 400 milliamp, LNA Current Source output on this port. The DC block will protect any test equipment connected directly to J7.

electromagnetic levels.

3.3 CONFIGURING THE XSAT

The XSAT is a complete RF Down Converter Terminal, RF Up Converter Terminal, and RF High Power Amplifier (HPA) in a single weather safe package. The following paragraphs will define the meaning and use of all of the controllable parameter of the XSAT.

3.3.1 FREQUENCY

Both the Receiver frequency and the Transmitter frequency are user configurable. The receiver frequency can be selected to any frequency divisible by either 1.0 MHz or 2.5 MHz in the valid Rx frequency range. The transmitter frequency can be selected to any frequency divisible by either 1.0 MHz or 2.5 MHz in the valid Tx frequency range.

Associated Remote Command(s): DFQ= , UFQ=

3.3.2 ATTENUATION

Both the Receiver attenuation and the Transmitter attenuation are user configurable. The receiver attenuation can be selected between 00.00 and 20.00 dB in 0.25 dB increments. The transmitter attenuation can be selected between 00.00 and 25.00 dB in 0.25 dB increments.

Associated Remote Command(s): DAT= , UAT=

3–3

XSAT7080 X-Band Transceiver Revision 0 System Operation MN/XSAT7080.IOM

3.3.3 GAIN OFFSET

Both the Receiver and the Transmitter Gain Offsets are user configurable. The Gain Offset are only used in redundant configurations. The user can use these parameters to adjust for gain difference between two XSAT Transceivers used in a 1:1 redundant configuration. The offset can be selected between 0.00 and –4.00 dB in 0.25 dB increments.

Associated Remote Command(s): DGO= , UGO=

3.3.4 MUTE MODE

The XSAT offers two operating modes with regards to frequency changes and unit muting. The two modes are; ‘muted after frequency change’ and ‘unmuted after frequency change’.

• If the Mute Mode is set to ‘1’, the firmware will leave the IF or RF muted following a change to either the Down Converter Frequency or Up Converter Frequency respectively. The operator can then ‘unmute’ the unit using the commands in the next section.

• If the Mute Mode is set to ‘0’, the firmware will automatically ‘unmute’ the IF or

Associated Remote Command(s): MUT=

3.3.5 MUTE

The output state of both the Receiver and the Transmitter are user controllable. The receiver output state (the ‘IF IN’ port, J1) will be ON only if the following two requirements are met:

The transmitter output state (the ‘RF OUT’ port, J7) will be ON only if the following three requirements are met:

Associated Remote Command(s): DMU= , UMU=

RF following a change to the Down Converter Frequency or Up Converter Frequency respectively. This assumes that the unit was ‘unmuted’ prior to the frequency change and that there are no faults following the change. The factory default for this mode is ‘1’.

(1) The receiver hardware must be fault free

(i.e. No Synthesiser or IFLO faults).

(2) The receiver must be unmuted (i.e. DMU=0 ).

(1) The transmitter hardware must be fault free

(i.e. No Synthesiser or IFLO faults). (2) The transmitter must be unmuted (i.e. UMU=0). (3) The transmitter Amplifier must be ON (i.e. AMP=1).
