Manufacturer:HP Refurbished by:Allwin*1 Corp HP***5B Semiconductor Parameter Analyzer Designed for production-line and laboratory use, the HP***5B is the electronics industry&#**9;s first standalone instrument capable of complete dc characterization of semiconductor devices and materials. It stimulates voltage-and current-sensitive devices, measures the resulting current and voltage responses, and displays the results in a user-selectable format (graph, list, matrix, or schmoo) on a built-in CRT display. An on-board programmable calculator provides real-time calculation of voltage/current-dependent parameters, such as the current gain (HFE) and transconductance(gm) of transistors, which can also be displayed on the CRT. A number of powerful graphic analysis tools*-marker, cursor, line function, and interpolation*-enhance the HP ***5B&#**9;s basic capabilities and provide fast, accurate analysis of semiconductor devices, leading to increased production yields and improved device quality. Four built-in source monitor units (SMUs) are the heart of the HP ***5B. Each SMU can be independently programmed to function as either a voltage source/current monitor or a current source/voltage monitor. Thus a bipolar transistor, for example, can be completely characterized in common-base, common-emitter, and common-collector configurations without changing connectionsoonly changing the SMU�s operating modes is required. The HP ***5B is also equipped with 2 voltage sources and 2 voltage monitors for measurements on devices having more than 4 terminals, such as ICs. The HP***5B can be controlled from the front panel via the HP-IB (standard), or by measurement setups stored on diskettes. Displayed information*-measurement setups, auto-sequence programs, and measurement results can be dumped directly onto an external graphics plotter to obtain publication quality hard copies.
