18:32, 11/07/2024

Circular 08/2018/TT-BTTTT has been promulgated by the Ministry of Information and Communications of Vietnam on the National Technical Regulation on Electromagnetic Compatibility for Multimedia Equipment - Emission Requirements.

Standards and limits for ensuring the guided radiation emission method in Vietnam are specified as follows:

Clause	Coupling Device	Basic Standard	Verification Testing Method	Measurement Setup	Measurement Procedure and Interpretation
8.1	AMN	Clause 7 of CISPR 16-2-1:2008	Clause 4 of CISPR 16-1-2:2003	Annex C	Use the measurement procedure specified in B.3. Apply the impedance and phase requirements of CISPR 16-1-2 in the frequency range from 0.15 MHz to 30 MHz.
8.2	AAN	Clause 7 of CISPR 16-2-1:2008	Clause 7 of CISPR 16-1-2:2003 applies the requirements in Table C.2 of this standard	Annex C and B.4.1.1	Use the measurement procedures specified in B.3 and B.4.1.1. Use the clarifications in B.3.6.
8.3	Current Probe	Clause 7 of CISPR 16-2-1:2008	5.1 of CISPR 16-1-2:2003	Annex C and B.4.1.1
8.4	CVP	Clause 7 of CISPR 16-2-1:2008	5.2.2 of CISPR 16-1-2:2003	Annex C and B.4.1.1
8.5	Use of adaptive networks and combinations for voltage measurement	Not applicable	B.4.2	B.4.2	Use the measurement procedures specified in B.4.2 for measuring undesired emission voltage at the tuner port of TV/FM broadcast receivers
8.6	Use of adaptive networks for voltage measurement within 75 Ω impedance	Not applicable	B.4.3	B.4.3	Use the measurement procedures specified in B.4.3 for measuring desired signal and emission voltage at the output port of the RF modulator

More details can be found in Circular 08/2018/TT-BTTTT, effective from July 01, 2019.
