General Information

1.0 INTRODUCTION

This manual contains installation, operation, and maintenance information for the Integrated L-Band Up/Dn Converter manufactured by VertexRSI, Longview, Tx. Information is organized according to section. Within each section the pages, figures and tables are numbered by section and by order of appear- ance within the section. Unless otherwise noted, any information about the unit applies to the LT-3600, Base Part Number 201667.

1.1 SAFETY INFORMATION

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

WARNING

A continuous safety earth ground must be provided from the main power source through the main power cord. This is provided in the power cable shipped with the unit. If this power cord is damaged, it should be replaced with cord of equal or better specifications. This cord can be obtained from VertexRSI.

Servicing instructions are for use by trained personnel only. To avoid dangerous electric shock, do not perform any servicing unless qualified to do so. Do not replace components with the power cord connected to the equipment.

WARNING

Some of the adjustments described in this manual are performed with power applied while protective covers are removed.

Always be careful not to come on contact with dangerous voltages while performing these procedures, and never work alone.

With power applied to the unit and the cover removed, be aware that a rotating fan is operating.

1.2 GENERAL INTRODUCTION

This manual provides operation and service instructions for the Integrated L-Band Up/Dn Converter. The unit consists of a power supply, forced-air cooling system, microprocessor- based CCA (circuit card assembly) and control circuitry and the modules required for up and down conversion. It incorporates extensive monitor and control functions that are accessible from the front panel as well as through a remote serial bus. A general description of the front and rear panels is given in Sections 1.5 and 1.6. A description of the Keypad and Display can be found in Section 3.

The Integrated L-Band Up/Dn Converter is housed in an enclosure destined for mounting in a standard EIA 19-inch rack, requiring a 1.75-inch high vertical space.

1.3 PURPOSE OF EQUIPMENT

The Integrated L-Band Up/Dn Converter is a fully synthesized up and down converter covering 575 or 1000 MHz bandwidth receiving RF frequencies in up to 125 kHz steps. The unit incorporates extensive monitor and control functions that are accessible from the front panel as well as through a remote RS- 232/422/485 bus.

The LT-3600 can be configured to accommodate various requirements involving an IF of 70 or 140 MHz, non-inverted or inverted spectrum, with standard or high- stability 10 MHz reference oscillator or any combination the user desires. Combined with jumper selectable and user programmable options, the LT-3600 is flexible to user requirements.
