IEC 60728-3-1:2012 is applicable to the methods of non-linearity measurement for cable networks which carry only digitally modulated television signals, sound signals and signals for interactive services. These methods take into account the specific signal form and behavior of digitally modulated signals which differ from the analogue broadcast signals represented mainly by the … [Read more...]
Standards
Standard for Integrated Circuits and Measurement of EMI and Radiated Immunity
IEC 62132-8:2012, Integrated circuits - Measurement of electromagnetic immunity - Part 8: Measurement of radiated immunity - IC stripline method, specifies a method for measuring the immunity of an integrated circuit (IC) to radio frequency (RF) radiated electromagnetic disturbances over the frequency range of 150 kHz to 3 GHz. The standard is applicable to integrated circuits, … [Read more...]
Standard for Antenna Calibrations, Characteristics and Compliance
CISPR 16-1-5 specifies the requirements for calibration test sites used to perform antenna calibrations, as well as the test antenna characteristics, calibration site verification procedure and site compliance criteria. Measurement instrumentation specifications are given in CISPR 16-1-1 and CISPR 16-1-4. Further information and background on uncertainties in general is given … [Read more...]
FCC Petitioned to Regulate Cellphone Signal Boosters
A new update to an FCC petition calls for tighter regulations on cellphone signal boosters. Wilson Electronics, T-Mobile, and Verizon Wireless have jointly filed two standards, which propose consumer cellular signal booster protection regulations. The first is a revised version of technical specifications for consumer boosters designed to operate on multiple frequency bands in … [Read more...]
Proposed Compromise for the 2.3 GHz Band
AT&T and Sirius XM are asking the FCC to adopt new rules to limit interference between Satellite Digital Audio Radio Services and Wireless Communications Services, both of which have been operating for the past 15 years in the 2.3 GHz band. Specifically, the new rules provide for everything from the prohibition of mobile transmitters in the WCS C- and D-blocks to AT&T's … [Read more...]
Modifying Allowable Power Levels and Interference Protections
A new way of determining allowable power levels and interference protections for radio frequency spectrum licensees is up for consideration within the Federal Communications Commission. An FCC staff working paper suggesting a market-based approach to modifying service rules was released. Read More … [Read more...]
FCC to Review Mobile-Phone Radiation Safety
The U.S. Federal Communications Commission plans to ask whether its standards protect people from mobile-phone radiation, a question it hasn’t posed in 15 years, as people use smartphones for longer, more frequent calls. A formal enquiry would review the FCC’s standards with the concerns of more frequent use, longer-use, new mobile-phone technology, and use by children in … [Read more...]
Microwave Therapy Equipment Safety Standard
IEC 60601-2-6:2012 specifies the minimum requirements considered to provide for a practical degree of safety in the operation of microwave therapy equipment. This particular standard amends and supplements IEC 60601-1 (third edition, 2005 and amendment 1, 2012). This second edition cancels and replaces the first edition of IEC 60601-2-6, published in 1984. This edition … [Read more...]
HEMP Immunity Test Methods for Equipment and Systems
IEC 61000-4-25:2001+A1:2012 describe immunity test levels and related test methods for electrical and electronic equipment and systems exposed to high-altitude electromagnetic pulse (HEMP) environments. Specifications for test equipment and instrumentation test set-up, test procedures, pass/fail criteria, and test documentation requirements are also defined by this standard. … [Read more...]
Determining Space for Capacitors and Resistors with Unidirectional Terminations
IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the … [Read more...]
