Appendix C: Certifications and EMI Compliance
SmartBits Compliance with CE Requirements
214 SmartBits System Reference
1 All cables must be terminated, both at the SmartBits and at the DUT. Do not leave an
unused port with a cable plugged in and dangling.
2 Use only certified cable in any SmartBits Ethernet port (both control port and test
ports).
3 Use only yellow optical cable with SmartBits ports that support single-mode optics.
4 Use only orange or gray optical cable with SmartBits ports that support multi-mode
optics.
5 All SmartCards/modules should be fully inserted into the chassis, and all thumb
screws should be tightened.
6 In a crowded engineering prototype lab, be careful of the layout of test cables used to
connect the SmartBits and devices under test. Avoid passing test cables over or under
other DUT or live equipment. If test cables are very long, avoid looping cables around
live equipment.
7 Use the ferrite clamp supplied with each SmartBits chassis on one end of the Ethernet
cable connecting the SmartBits to the LAN or to the PC.
8 Use common sense. For example, a test or control cable laid over the AC power sup-
ply of an open DUT will most likely produce faulty measurement results.
