Overview
IEC TR 62002-3:2008 describes the minimum requirements for a measurement interface designed for mobile and portable DVB-T/H (Digital Video Broadcasting - Terrestrial/Handheld) radio access terminals. This interface is essential for use in test systems that verify terminal conformance according to IEC 62002-1 and IEC 62002-2. The standard is particularly focused on hand-held portable convergence terminals (terminal category c)), but it may also be used with other terminal types.
The measurement interface enables test systems or manual operators to control the terminal and access performance and degradation data, ensuring compliance with international DVB-T/H standards and fostering interoperability in the global digital broadcasting ecosystem.
Key Topics
-
Terminal Measurement Interface Requirements
- Defines how terminals should communicate measurement data to test systems.
- Supports both manual and automated (test system controlled) measurement operation modes.
- Provides comprehensive messaging protocols using ASCII character messages over various physical interfaces (USB, UART/RS-232, Bluetooth, WLAN, IR).
-
Degradation Criteria and Reporting
- Enables the test system to read signal quality metrics such as bit error rate (BER), frame error rate (FER), and Multi Protocol Encapsulation Forward Error Correction frame error rate (MFER).
- Supports conformance testing using multiple degradation criteria as specified in IEC 62002-2.
-
Measurement Modes and Commands
- Describes command structures for starting, stopping, and restarting measurements.
- Details the required measurement parameters, such as frequency, bandwidth, modulation, and more.
-
Signal Quality Reporting
- Specifies the format for reporting signal quality and lock status from the terminal to the test system.
- Includes parameters like signal strength, carrier-to-noise ratio, error rates, and synchronization time.
