Multimedia Equipment Emissions requirements


There are a lot of questions surrounding the appication of CISPR 32 and what it means for your products. We will try to cover all the basics so that you will understand what is required to prepare your products to test for CISPR 32.

CISPR 32 was designed to replace CISPR 13, CISPR 22 and EN 55103-1, which were previously used to show compliance to emission regulations for receivers and ITE equipment. CISPR 32 was adopted by the EU under the scope of EN 55032. It was set to be mandatory as of 5 March 2017.

The approach used in CISPR 32 is to identify tests which can be applied to MultiMedia Equipment (MME).

MME included under CISPR 32

  • MultiMedia Equipment
  • Information Technology Equipment
  • Audio Equipment
  • Video Equipment
  • Broadcast Receiver Equipment
  • Entertainment Lighting Equipment

Why the need for CISPR 32?

CISPR 32 was created to address the fact that many of today’s IT equipment integrates multiple features and capabilities. In the past, these various functions were assessed using different compliance standards. Unsurprisingly, the differing limits and test methods for each of these standards had the potential to add significant time and cost to the testing process.

CISPR 32, therefore, is a natural evolution designed to test today’s technology in all its multi-functional glory. Computers are just one example of a product that still performs basic functions while also integrating new features like video and radio. Rather than test to multiple standards, product developers need only test to CISPR 32. While CISPR 32 is not an exact merge of the two previous standards, it does closely resemble CISPR 22 in several ways:
  • Telecommunications port conducted emissions limits specified over 150 kHz to 30 MHz
  • Radiated emissions limits specified over 30 MHz to 6 GHz
  • Radiated emissions limits from FM receivers at the fundamental and harmonics of the local oscillator frequency
