1 Introduction
1.1 General
This document is the Hardware User’s Manual for the Version 2 Lumistar LS-25-D Multi-band RF
Downconverter and the LS-25 Multi-band FM Receiver. These products represent Lumistar’s 2nd
generation of RF receiver designs that have replaced the original LS-25 receiver series. Figure
1-1 on page 8 contains detailed model number construction. This document applies to all model
combinations indicated by this figure. The original product line is described in User Manual
U250401. Consult the factory for a copy of this document.
The intent of this document is to provide physical, functional, and operational information for the
end user including hardware configuration, interconnection and software interfaces for the device.
Both receivers implement a switching dual/single-superhetrodyne receiver design. The designs
provide for the Downconversion for up to three RF bands, providing two 70MHz second
intermediate frequency (IF) outputs as well as AM demodulation of the input signal. The product
may be configured with up to 12 IF bandwidth filters. In addition to the functions of the LS-25-D,
the LS-25 provides an additional FM demodulation stage and up to12 selectable video filters
applied to the demodulated PCM signal.
Table 1-1 on page 9 provides specifications for electrical, mechanical, and operational
characteristics of the LS-25-D and LS-25 receiver product line. A block diagram of the receiver is
shown in Figure 1-2 on page 10.
1.2 Manual Format and Conventions
This manual contains the following sections:
Chapter 1 provides a brief product overview and technical specifications
Chapter 2 provides receiver theory of operation
Chapter 3 provides installation and configuration instructions
Chapter 4 provides info on the LS-25/25-D LDPS software application
Chapter 5 provides programming information
Throughout this document, several document flags will be utilized to emphasis warnings or other
important data. These flags come in three different formats: Warnings, Cautions, and
Information. Examples of these flags appear below.
