描述：Keysight B2900A Series Precision Source ? Measure Units are cost-effective source?measurement solutions offering superior performance and a best-in-class graphical user interface. The Keysight B2900A series of SMUs provide best-in-class performance for a modest price. They have broad voltage (210 V) and current (3 A DC and 10.5 A pulsed) sourcing capability, excellent precision (minimum 10 fA?100 nV sourcing and measuring resolution) and possess a superior color LCD graphical user interface. In addition, several task-based viewing modes dramatically improve productivity for test, debug and characterization. The Keysight B2900A series consists of four models, the B2901A, B2902A, B2911A and B2912A, differentiated through their measurement specifications and by the number of SMU channels (one or two) they support. This makes it easy to select the exact price/performance point to meet your testing needs. . * Features: ** * Integrated voltage?current 4-quadrant precision source and measurement capabilities for easy and accurate I?V measurement * Wide coverage up to 210 V, 3 A DC?10.5 A pulse * 10 fA?100 nV minimum measurement resolution (6-1?2 digits) * 10 fA?100 nV minimum sourcing resolution (6-1?2 digits) * The 4.3" front panel color display supports both graphical and numerical view modes * High resolution arbitrary waveform generation (AWG) and list sweep functions (10 μs minimum interval) * High speed digitizing capability (maximum 100000 points?s sample rate) * Free application software to facilitate PC -based instrument control * IVI-COM drivers, and SCPI supporting conventional SMU command set for basic compatibility * LXI class C, USB2.0, GPIB, LAN and digital I?O interface
