Prodrive Technologies since 2007
Active in EMC design and testing since 2009
Some examples of products we develop and manufacture at Prodrive:
• Industrial motor drives
• Medical imaging (MRI gradient amplifiers, image processing)
• Industrial high-performance computing (semi-conductor industry)
• Consumer electronics
Since 2015 the Prodrive EMC lab is RvA accredited.

CISPR32 vs CISPR 22
Presentation structure derived form CISPR32
CISPR 32 Ed. 2.0 CISPR 22 Ed. 6.0

Slide 5 of [23]
CISPR 32 / EN55032 (IDT)
• 1st edition 2012
• 2nd edition 2015
EMC Directive 2014/30/EU: no mentioning of 55022 and 55032 yet (list of 2016-05-13) (know issue that list is missing a lot of standards)
EMC Directive 2004/108/EC:
2017-03-05 Date of withdrawal of presumption of conformity.
Replacement of EN55022 by 2012 edition of EN55032
(last list of old directive 2016-01-16)
Also listed under new Radio Equipment directive
Slide 6 of [23]
CISPR 32 Emission – CISPR 35 Immunity
Replacing
CISPR 22 Emission – CISPR 24 Immunity
CISPR 13 Emission – CIPSR 20 Immunity
Slide 7 of [23]
CISPR 32
• Multimedia equipment
• Combines scope of CISPR 13 (sound and television broadcast receivers) and CISPR 22
CISPR 22
• Information technology equipment
• Examples: PC, printer, copier, computer monitor

CISPR 32
Slide 10 of [23]
Class A
• All other environments
• Examples: Servers, professional network switch, Industrial PC.
• Possible to move 10m away for radio reception
Class B
• Residential environment
• Examples: Tablet, PC, TV, consumer network switch or router
Classification in CISPR 32 is similar to CISPR 22
Slide 11 of [23]
Slide 12 of [23]
Radiated emission 30MHz-1GHz:
• Limits are the same
Radiated emission 1GHz-6GHz:
• Limits and methods are the same
Conducted emission mains:
• Limits are the same
Slide 13 of [23]
CISPR 32
• Class A/B 30MHz-1GHz:• Limits defined at 3 meter and 10m
• Semi-anechoic/OATS
• Full anechoic chamber
Specifics:
• Limits for harmonics of FM receivers
• outdoor units for home satellite receivers
CISPR 22
• Class A/B 30MHz-1GHz :• Limits defined at 10m only
• Semi-anechoic
• Class B can be measured at 3m with correction.
Slide 14 of [23]
CISPR 32
• Limits defined for:• AC power port
• Asymmetric mode:
• Wired network
• Optical port with metal shield
• Broadcast receiver tuner port
• Other antenna port
• Differential voltage
• TV/FM receiver tuner port
• RF modulartor output port
CISPR 22
• Limits defined for:• AC power port
• Asymmetric mode
• Telecommunication port
Slide 15 of [23]
CISPR 32
• Modules to be sold without the host now explicitly included.
• Modules classified• Internal (e.g. Hard disk)
• Plug-in (e.g. USB thumb drive)
• Mounted (e.g. PCI sound card)
• External (e.g. remote control)
Slide 16 of [23]
A host shall be tested with modules so that the resulting system is representative of typical use.
Slide 17 of [23]
Modules intended to be sold separately shall be tested:
• With at least one representative host system.
• Termination as specified for port type
• The module shall perform the function specific to the module
Slide 18 of [23]
CISPR 32
• In Annex B (normative)
• Audio (1kHz sinusoidal signal)
• Video
• Broadcast receiver antenna port
• Network port
CISPR 22
• In Annex G (informative)
• Visual display
• Facsimile device
• Telephone sets.
• General terms used like maximum or worst-case
Slide 19 of [23]
Complexity level
Display Description Equipment Example
4 (most) Colour bars with moving element
ITU-R BT.1729 based
Digital TV, DVD, PC, video game
3 Colour bars ITU-R BT.471-1 Analog TV, displays on camera’s ,displays on photo printer
2 Text image Pattern consisting of H
POS terminal, computer without graphic capabilities
1(least) Typical display
Most complex display possible on device
Product with proprietary display not capable of any of the above.

Slide 21 of [23]
CISPR 32
• Ports
• Broadcast receiver port• Example data for Terrestrial TV: DVB-T, ISDB-T, ATSC, DMB-T
• Example data for Satellite TV: DVB-S, ISDB-S
• Example data for Cable TV: DVB-C, ISDB-C, ATSC
• Network port:• Ports supporting multiple rates only measure at max rate.
(100Base-T, 1000Base-T)
• Pseudo random message (example compressed data)
Slide 22 of [23]
Slide 23 of [23]
Change Description Impact
Scope Now also includes broadcast receivers During Specification
Class A/B No change in definition -
Limits Same limits -
Testing More options on test locations Test lab selection
Modular EUT Better definition of test setup Design and testing
EUT exercising Better definition especially for ports Design and testing
Overall: Probably no big technical challenges for product designer
Products that comply to CISPR22 are likely to pass testing against CIPSR 32
