概要（Overview）

The highly-portable Spirent Communications SmartBits 200 (SMB-200) is a 4-port performance analysis system that can be easily dispatched to the test site. With GPS support, the SMB-200 can also be used to create a distributed performance analysis system for measuring endto-end performance, including one-way latency and latency variation. The SMB-200 is based on the same industry standard as the SMB-2000. The SMB-200 and SMB-2000 also share the same software and SmartCards.
