What is CISPR 32 and what equipment does it cover?

For example, CISPR 12 and 25 provide emissions test methods and limits for the automotive RF Emissions, and CISPR 11 is the emissions standard for industrial, scientific, and medical equipment.

Many of the CISPR RF emissions standards become the harmonized standards for the European Union EMC Directive. When published in the Official Journal, CISPR standards take the Euro-norm prefix “EN”, as in the case of EN 55032.

CISPR 32 is a specific standard developed for a class of electronics described as Multi Media Equipment (MME).

MME are electronics that incorporate a range of functions that include those in Information Technology Equipment (ITE), audio equipment, video equipment, and broadcast receiving equipment. MME also covers entertainment lighting control equipment as well as combinations of all these equipment types.

What is its relationship between CISPR 32 and CISPR 22 and CISPR 13?

CISPR 32 now covers equipment that is currently within the scope of two separate specifications: CISPR 22 for Information Technology Equipment and CISPR 13 for Sound and Television Broadcast

What are the tests?

The tests include conducted emissions and radiated emissions.

The conducted measurements are performed:

· On the AC Mains port

· On the DC Mains port

· On the network port such as on an Ethernet connection

· On the receiver port for devices with detachable antenna ports

How do the limits compare?

The AC Mains, DC Mains, Network Port, and Antenna Port conducted emissions limits in CISPR 32 are the same as compared to those currently in CISPR 22 and CISPR 13

The radiated emissions measurements and limits in CISPR 32 are the same as compared to those in CISPR 22 and CISPR 13.

CISPR 32 provides more detailed information on the specific emissions limits for various ports on the DUT, including emissions on the shields of optical fiber ports.
