IEC 61319-2-1997 PDF

Full title and description

Interconnections of satellite receiving equipment — Part 2: Japan. This international standard specifies recommended interconnection arrangements and matching values for satellite receiving equipment intended for individual television and sound broadcast reception in the 12,5 GHz to 12,75 GHz band; it is oriented to application in Japan and defines interfaces between outdoor and indoor equipment (polarizers, polar switchers, LNBs, connectors, antenna-selection devices and receiver/decoder interfaces).

Abstract

IEC 61319-2:1997 defines interface requirements and electrical/mechanical characteristics for items in a satellite receiving chain specific to the Japanese operating band (notably 12.5–12.75 GHz). Key elements covered include interfaces for mechanical and magnetic polarizers, polarisation switchers, the low-noise block converter (LNB) to receiver interface including first-IF impedance and connector types, antenna-source selection interfaces, and interfaces to satellite radio and conditional-access equipment. The document is concise (informative annex/bibliography included) and intended to ensure compatibility between outdoor and indoor components.

Scope

The standard applies to the electrical and mechanical interfaces between satellite-receiving outdoor components (polarizers, polarisation switchers, LNBs, antenna-selection devices) and indoor equipment (receivers, external descramblers/decoders and digital radio receivers) when used for individual television and sound broadcast reception in the 12,5–12,75 GHz band. Safety requirements are outside the scope; the focus is on compatibility, matching values, impedances, connector types and signal/output arrangements relevant to the Japanese market.

Key topics and requirements

• Interface requirements for mechanical and magnetic polarizers and polarisation switchers (mechanical dimensions, control interfaces and signal paths).
• Requirements for the LNB to receiver interface: characteristic impedance at the first intermediate frequency (IF), single-input signal arrangements and connector specifications.
• Connector type recommendations and mechanical mating details for outdoor/indoor interconnections.
• Interfaces and control signals for selecting between multiple antenna sources or satellite positions (antenna switching/selection interfaces).
• Interfaces between satellite receivers and external descramblers, conditional-access systems and set-top decoders.
• Interfaces and audio output requirements for digital satellite radio receivers (DSR) and related audio-frequency outputs.

Typical use and users

Primary users are equipment manufacturers (LNB and receiver designers), test laboratories, broadcast equipment integrators and installers who need to ensure interoperation of outdoor and indoor satellite components for systems operating in the Japanese 12.5–12.75 GHz band. National standards bodies, product certification bodies and procurement teams specifying compatible consumer satellite equipment for the Japanese market also reference this part.

Related standards

This part is one element of the IEC 61319 series addressing regional interconnection profiles for satellite receiving equipment. Closely related documents include IEC 61319‑1 (Part 1: Europe) and other regional parts (e.g., Part 3 for North America as published/adopted by relevant bodies). Other related IEC/EN standards and cable-distribution and connector standards (for example those governing RF connectors and cable-network equipment) are commonly referenced when implementing or testing the interfaces specified in IEC 61319-2.

FAQ

Q: What is this standard?

A: IEC 61319-2:1997 is the IEC international standard that specifies interconnection interfaces and matching values for satellite receiving equipment targeted at the Japanese reception band (12.5–12.75 GHz).

Q: What does it cover?

A: It covers mechanical and electrical interface requirements between outdoor satellite front-end components (polarizers, polarisation switchers, LNBs, antenna-selection hardware) and indoor equipment (receivers, external decoders, DSR), including impedance, connector types, control interfaces and audio outputs. Safety aspects are not addressed.

Q: Who typically uses it?

A: Equipment manufacturers, system integrators, test laboratories, installers and standards/ procurement professionals working with satellite reception equipment for the Japanese market.

Q: Is it current or superseded?

A: IEC 61319-2 was published as Edition 1.0 on 23 April 1997. The IEC webstore entry shows the original publication metadata (edition, pages and stability information) as published; users needing the current administrative status, confirmations of withdrawal or any amendments should verify the IEC catalogue or national adoption records for updates beyond the original publication.

Q: Is it part of a series?

A: Yes — IEC 61319 is a multi‑part series addressing regional interconnections of satellite receiving equipment (for example Part 1: Europe, Part 2: Japan and other regional parts). Implementers commonly consult the appropriate regional part for the market in which the equipment will operate.

Q: What are the key keywords?

A: Satellite, LNB, polarizer, polarisation switcher, IF interface, connectors, 12.5 GHz, 12.75 GHz, antenna switching, digital satellite radio, conditional access.
