Compared with the technical content of the two documents GB/T 17618-2015, compared with the above two documents, except for structural adjustment and editorial changes, the main technical
The changes are as follows.
--- Wider scope of application, suitable for multimedia equipment, including multimedia equipment for professional use and GB/T 9383-2008 and
GB/T 17618-2015 applicable equipment;
--- Added the relevant content of EUT function divided into direct function and indirect function (see 4.1);
--- Delete the input immunity test (see 4.3.1, 4.3.2, 5.3 of GB/T 9383-2008);
--- Delete the shielding effect test (see 4.3.4 and 5.5 of GB/T 9383-2008);

This document is modified to adopt CISPR35.2016 "Electromagnetic Compatibility Immunity Requirements for Multimedia Equipment".
Compared with CISPR35.2016, this document has no structural adjustment. The technical differences and their reasons are as follows.
--- Regarding normative references, this document adds references to GB 3174, GB/T 4365, ISO /IEC 17025.2005, and deletes
IEEE802.3, in order to adapt to the technical conditions of our country.
--- Delete the definition of EUT (3.1.15) and add it to 3.2 as an abbreviation (see Chapter 3). As an abbreviation more
It is helpful to understand this document, so delete and add this content.

And/or 110V (±10V) rated voltage test, the frequency is 50Hz or 60Hz, which can usually meet the requirements of EUT for global use.
"Use;" is "the working voltage and frequency should meet the specifications of the EUT;" (see Chapter 5). Since our country has a relatively common rated
voltage, so change this.
--- Changed the example of digital broadcasting signal parameters (see Table A.1). Due to the special requirements of my country's broadcasting system, this
content.
---Added "The EUT that establishes communication through the wireless network, during the test, the applied disturbance signal frequency should not be in the EUT's
within the working frequency band. ” (see Table H.1). Since my country’s wireless communication system has its special requirements, this content is added.
--- Change the "800MHz" in the title of Appendix I and the relevant position of the appendix to "700MHz", and increase the relevant content of 5G mobile communication.

The content of the relevant institutions may not appear in this document, and the added abbreviation is the content of the broadcast signal system in our country, so delete it.
Remove and add to this.
--- Change the point frequency test in the radiated disturbance immunity of the 1GHz~6GHz frequency band to the sweep frequency test, and increase the radio frequency of the telephone function
Frequency electromagnetic field disturbance additional point-frequency test of the following frequencies. 1.8GHz, 2.6GHz, 3.5GHz, 5GHz (see Chapter 5). Depend on
Due to the rapid development of related technologies in my country, the radiated disturbance immunity in the 1GHz~6GHz frequency band is subjected to sweep frequency tests and 1GHz~
The additional point frequency test of radio frequency electromagnetic field disturbance of the telephone function in the 6GHz band is necessary, so this content is changed and added.
--- Changed the performance criteria of the network function (see Appendix F). Since it is necessary to specify the static network function according to the relevant verification test conclusions
The concept of the error rate at the level, and it is necessary to appropriately relax the performance criteria of F.4.3, so this content is changed.
--- Added the relevant parameters of FAST (G.fast) (see Appendix F). Due to the rapid development of related technologies in my country, this increase
content.
The following editorial changes have been made to this document.
--- Change the name of this document to "Information Technology Equipment, Multimedia Equipment and Receivers Electromagnetic Compatibility Part 2.Immunity
Require".
---Changed "The measurement point suitable for 625-line camera is at the midpoint of line 160" to "The measurement point suitable for 325-line camera is at the midpoint of line 160"
160 line" (see Table D.2). This is changed due to an error in the International Standard.
--- Deleted the abbreviation SES (see Chapter 3), and changed "SES" in F.4.2.2 to "Severely Errored Seconds". Due to international standards
The wording is incorrect, so this content has been changed.
--- Change "Not Applicable" to "Use the Display Criteria in Appendix D to Indirectly Evaluate Network Functions" (see Table J.4). Due to the international standard table
There is an error in the description, so this content is changed.
