WT210 is listed for Standard Performance Evaluation Corporation (SPEC) Power Efficiency Benchmarking
As internet and personal computer usage expand at exponential rates, so does a growing demand for energy efficient computers and servers. Leading this movement is the Standard Performance Evaluation Corporation (SPEC), who publishes benchmarks that evaluate the power and performance characteristics of volume server class and multi-node class computers. SPEC is a non-profit corporation, formed to establish, maintain and endorse standardized benchmarks for the latest generation of high-performance computers.
The SPECpower_ssj2008 V1.10 Industry-Standard Benchmark is the first of its kind. This benchmark measures power consumption in relation to the performance of server-class computers. It makes use of highly accurate Power Analyzers to make these power measurements. Some of the key requirements of the Power Analyzers listed by SPEC are:
• Over all measurement accuracy of 1% or better
• Store measurements to an external device at a rate ≥ 1/sec
• Crest Factor of at least 3 or greater
• Start and Stop recording/logging from an external controller
• Analyzer calibration must be traceable to NIST (U.S.A)
The Yokogawa WT210 is listed and endorsed as an accepted device by SPEC for performing these accurate power measurements. With a bandwidth of DC and 0.5Hz to 100KHz, the WT210 offers a base accuracy down to 0.1%. The meter can be controlled by an external controller using either RS232 Serial or GPIB communication interfaces and can provide update rates as fast as 10/sec (100msec).
