IEC 60244-2B:1969 provides technical guidance for measuring transmitter bandwidth, out-of-band power, and the power of non-essential oscillations, with a specific focus on the modulating signals used in those measurements. For engineers and laboratories reviewing radio transmitter performance, this document helps define a consistent basis for technical evaluation and documented evaluation. It is especially relevant where measurement repeatability, conformity assessment, and compliance workflows depend on using comparable test conditions and accepted methods.

Purpose of IEC 60244-2B:1969

The purpose of IEC 60244-2B:1969 is to support measurement methods for radio transmitters by specifying the modulating signals used when assessing bandwidth and out-of-band power. As part of the broader measurement framework in the title, it is intended to help establish operational consistency during verification activities and laboratory evaluation. Organizations involved in technical review, engineering validation, or regulatory preparation may use it as a compliance reference when documenting transmitter characteristics and comparing results across test setups.

Compliance applications of IEC 60244-2B:1969

IEC 60244-2B:1969 is applicable in testing workflows for radio transmitters used in telephony and sound broadcasting, where controlled measurement of bandwidth-related behavior is important. It may be used by test laboratories, equipment manufacturers, and conformity assessment teams preparing technical documentation for product evaluation or procurement review. The document is also relevant when teams need a defensible method for assessing out-of-band emissions and other non-essential oscillations under defined test conditions, supporting technical compliance and quality workflows.

Benefits of IEC 60244-2B:1969

Using IEC 60244-2B:1969 can improve testing consistency and reduce ambiguity in how transmitter measurements are performed and reported. That supports better engineering documentation, more reliable comparison between test results, and stronger preparation for conformity assessment. For organizations managing compliance workflows, it can also lower technical risk by providing a clearer basis for review of bandwidth and out-of-band behavior. In procurement and validation settings, this helps teams evaluate whether equipment aligns with expected performance criteria and documentation requirements.
