Richard, Cameras, monitors, etc are not ITE. CISPR 22 does not apply to them.

That is consistent with the problem of long balanced pairs having common mode emissions. The standard also includes tests for coax and alludes to emissions caused by imperfect shielding. That seems to imply that a network of video products (e.g., cameras, monitors, muxes, VCRs, etc) with base band signals in coax would also be subject to testing. However, it is not clear that is what the authors had in mind. Comments?

But I agree that adding some more definitions of interfaces would help, also myself. Clause 6.3: Telecommunications port Point of connection for voice , data and signalling transfers intended to connect widely dispersed systems via such means as direct connection to multi-user telecom networks (e.g. PSTN, ISDN, xDSL, LAN (token ring, ethernet, etc) and similar networks. Note A port generally intended for connection of components of an ITE system under test (e.g. RS232, IEEE standard 1284 (parallel printer), USB, IEEE Std 1394 (fire wire) etc) and used in accordance with its functional specifications ( e.g. for the max. length of cable to be connected to it), is not considered to be a telecommunications/network port under this definition Regards, Kris This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
