The latest member of Agilent's family of USB modular instruments is the U2741A digital multimeter (DMM). The compact 5.5-digit DMM is roughly the size of a paperback book. It offers fast, 100-samples/s measurements and maximum input levels of 300 Vdc and 2 A. Ten measurement functions include DC voltage and DC current; true-RMS AC voltage and AC current; 2- and 4-wire resistance; frequency; diode test; continuity; and temperature. As with the other USB modular instruments, the DMM uses standard, high-speed USB 2.0 for plug-and-play connectivity. The bundled Agilent Measurement Manager software provides a familiar PC user interface, and the included IVI drivers allow users to program with Agilent VEE, MATLAB, C#, C++, Microsoft Visual Basic, or LabVIEW. The U2741A DMM costs $1,040. AGILENT TECHNOLOGIES INC., Santa Clara, CA. (877) 424-4536.
