The WE7000 is a new type of PC-based measurement instruments integrating YOKOGAWA’s analog, digital, and software technologies. The measuring station capable of holding various measurement modules can be connected to the computer with both the station and the computer can be connected to the Ethernet (10 BASE-T/ 100BASE-TX) or USB allowing for the construction of a high-speed, multi-channel, diversified measurement system. In addition, the optical interface module and optical interface card that are sold separately can be used to make connections using optical fiber cables (see Appendix 1, “Optical Interface”). Various measurement module sets are available including a digital oscilloscope, a function generator, a counter, and a digitizer which allows measurements from DC to high frequency regions. Because the insertion and removal of measurement modules and the addition of measuring stations are recognized automatically by plug & play, the system can be easily modified. Until now, PC-based measurement systems invoked complaints such as: “Writing programs takes too much time,” “Transferring of the measured data takes too long for practical use,” “Not enough space to combine multiple instruments,” and “Wiring is too complicated.” The WE7000 solves these problems and provides a measurement environment which incorporates multimedia.
