Precision, multi-purpose solutions for evolving test needs Series 2000 High Performance Digital MultimetersA G R E A T E R M E A S U R E O F C O N F I D E N C E•••••Meet our high performance familyEach Series 2000 Digital Multimeter offers a unique combination of measurement capabilitiesthat make them ideal for high speed production testing. Their half-rack design fits easily into just about any test rack or benchtop. With maximum resolutions from 61⁄2to 81⁄2digits and a variety of built-in capabilities, there’s sure to be a Series 2000 DMM that matches your application.Go to work with the right toolsSeries 2000 multimeters are essentials for anyone’s basic electrical toolbox because they combine all the measurement capabilities needed for electronic device and sub-system measurements, operational circuit measurements, and electronic product development and validation for bench and in ATE applications.Be confident of your measurement integrityAll Series 2000 DMMs are based on the same high speed, low noise 28-bit A/D converter technology for superior measurement precision, sensitivity, and traceability. The Models 2001 and 2002 incorporate five distinct processors for tighterA/D control, higher accuracy, more precise triggering, higher throughput, and support for a variety of advanced capabilities. Get high value plus high performanceA wide range of price and performance options are available, so it’s easy to find a cost-effective match for your application. Whether you need the speed and economy of the basic Model 2000, the ultra-high precision of the Model 2002, orsomething in between, there’s a Series 2000 DMM that’s right for the job. All Series 2000 models are capable of reading ratesof up to 2000 readings/sec (at 41⁄2digits).Migrate your applications easily from instrument to instrumentThe common SCPI programming and software architecture simplifies migrating applications to more capable instruments asnew test needs arise or when substituting a Keithley DMM for a meter from another manufacturer.Handle tomorrow’s test challenges with today’s test solutionSeries 2000 DMMs have earned a reputation for exceptional long-term performance and reliability. Each one is backed with a standard three-year warranty. Built-in measurement, signal conditioning, switching, and data communications functions giveyou the flexibility to repurpose your instrument readily as your test needs change over time.Functional overview................................4-5Series 2000 models................................6-7Series 2000 companion products (8)Higher channel count solutions (9)Selector guide......................................10-11For more information................Back cover3threeEasy-to-read vacuum florescent display with clear annunciatorsBuilt-in frequency counterSelectable reading rates up to 2000 rdgs/sFast, flexible triggeringEasy closed-case calibrationFast range and function changesData storage memory2- or 4-wire ohms measurementBuilt-in temperature measurement capabilitiesApplication: Low level resistance testingThe Model 2010 is made for low resistance applications like testing the reliability of electrical connectors. With a measurement range of 1µΩto 120M Ω, it ensures more precise low level readings. Device self-heating is minimized when testing low ohmscomponents, because resistance measurements can be made with source current as low as 100µA. The Model 2010’s dry circuit test mode clamps the open circuit voltage at 20mV to prevent punctures in any oxides or films that may have formed on contacts and connectors,so the measurement derived reflects the “in use” resistance. An offset compensated ohms function eliminates error-causing thermal effects from cabling and connections.A broad range of built-in functionsfour 4Trigger Link for fast, precise, repeatable triggering of multiple instrumentsBuilt-in scanner mainframe accepts optional switching cards for multi-point testingIEEE-488 bus simplifies controlling a wide range of GPIB instrumentsThe Model 2001’s multiple display capability makes it easy to gather several pieces of information simultaneously from different aspects of a single signal. One of these displays is ideal for power supply monitoring because it shows the DC voltage of the supply’s output, the AC noise level, and the frequency of that noise all at once,which simplifies tracking down the source of the noise and correcting it.Application: Power supply monitoring5fiveIndividualized solutions for specific application needsModel 2000: Get high accuracy without a high price tagThe 61⁄2-digit Model 2000 has unique capabilities that simplify building and upgrading automated production test systems. For example, the built-in limit testing function can be used to sort or grade components or assemblies. It also offers a full resolution reading rate (50 rdg/s) that’s nearly ten times faster than any other meter in its class and a maximum speed of 2000 rdgs/s. Built-in math functions let you make a variety of calculations on the acquired data without a computer controller.Model 2010: Resolve low level signals quickly and accuratelyWith a noise floor of just 100nV RMS, the 71⁄2-digit Model 2010 is designed for high accuracy millivolt- and microvolt-level measurements. It also wraps up all the functions needed for characterizing the resistance, linearity, or isolation of contacts, connectors, switches, or relays in a single instrument.With built-in capabilities like a low power ohms mode, dry circuit testing,offset-compensated ohms, and a 10Ωrange, the Model 2010 DMM is ideal for developing, validating, or production testing sensors, transducers, A/D and D/A converters, regulators, references, connectors, switches and relays.It’s equally appropriate for end-of-life contact testing per ASTM B539-90.Model 2001: Advanced features you never thought a DMM could offerThe Model 2001 couples exceptional accuracy (0.0018% basic),resolution, and sensitivity with measurement and mathematical capabilities rarely found in DMMs. Its internal peak detector can catch 1µs spikes, such as power supply spikes and transients, AC line power surges, and short-duration dropouts on components, as well as up to 1MHz for repetitive signals. With the Model 2001, it’s easy to measure AC peak value, average, and true rms directly to characterizethe signal thoroughly.The Model 2002’s unique one-phase four-wire ohms measurement capability makes it a good solution for high speed production testing of precision resistors. Two high and two low limits can be tied to the status of any of four protected digital outputs, so the Model 2002 can sort or grade the resistors automatically after testing. For QA tests on small samples, the front panel bar graph display makes it easy to determine the tolerances of individual resistors.Application: Precision resistor testingeight 6Model 2002: Truly usable 81⁄2-digit resolutionThe Model 2002 offers the same advanced features andfunctions as the Model 2001, then adds an extra decade ofresolution and broader DC voltage, temperature, and resistanceranges. The Model 2002’s performance is specified for a ±5°Cenvironment, not a ±1°C environment, and no daily re-calibration is required to stay in spec, so it’s ideal for highaccuracy production test applications. An “open lead” detectionfunction helps identify problems that could lead the system topass components that should have failed a test. Built-in digitalI/O capabilities and a pass/fail testing function simplifyconnecting it to a variety of handlers for fast, efficient devicebinning and sorting.Models 2015 and 2016: Audio analysis plus full-featured DMMsEach of these specialized instruments combines audio bandquality measurements and analysis with a full-function 61⁄2-digitDMM for production testing of audio devices and sub-systems.The Models 2016 and 2016-P provide twice the sine wavegenerator output of the Models 2015 and 2015-P forapplications that require test signals greater than 8Vrms. TheModels 2015-P and 2016-P offer additional processing capacityfor frequency spectrum analysis. All four models can measureTotal Harmonic Distortion (THD) over the complete 20Hz to20kHz audio band, as well as compute THD+Noise and Signal-to-Noise plus Distortion (SINAD). These capabilities are criticalfor applications such as assessing non-linear distortion in components, devices, and systems. Five industry-standardbandpass filters are provided for shaping the input signal for audio and telecommunication applications. Refer to theSelector Guide on pages 10-11 for specification information.Refer to the Selector Guide on pages 10-11 to compare the capabilities of different models. Application: THD analysis and frequency response The Model 2015, 2015-P, 2016,The Model 2015, 2016-P, 2016, and 2016-P can provide both time domain andfrequency domain measurements in a single test protocol. Keithley can help youconfigure a system for testing telecommunication devices, such as mobile phones.These instruments can perform a frequency domain analysis of the Total HarmonicDistortion (THD) and the first three harmonics as a function of frequency, as well as atime domain analysis of microphone circuit output voltage as a function of frequency.7nineBuilding blocks for a comprehensive system solution Plug-in scanner cardsTo create test and measurement systems with up to ten measurement points quickly and economically, choose fromthree plug-in scanner cards designed specifically for several Series 2000 DMMs. Just slide one of these cards into theoption slot on the meter’s back panel and you’ll combine scanning and measurement capabilities in a single instrument.The Model 2000-SCAN 10-Channel Scanner Card is designed for use with Model 2000, 2010, 2001, and 2002 DMMs.It supports multiplexing one of ten two-pole or one of five four-pole signals into the DMM and/or any combination oftwo- or four-pole signals.The Model 2001-SCAN Scanner Card is a high speed multiplexing scannercard developed for the Model 2000, 2010, 2001, and 2002 DMMs. This cardtransforms your meter into a high accuracy, high speed ten-channeldatalogger for a variety of mixed-signal applications. Two high speed solid-state channels on the card allow calculating ratio and delta when it’sinstalled in the Model 2001, 2002, or 2010.When used with a Model 2000, 2001, 2002, or 2010 DMM, the Model2001-TCSCAN Thermocouple Scanner Card provides up tonine channels of cold-junction compensated temperaturemeasurements and/or voltage, resistance, and frequencymeasurements. When the card is installed in the Model 2001 or2002, the DMM will linearize type J, K, E, R, S, B, and Tthermocouples automatically. When used with the Model 2001, 2002, or 2010, it allowsmeasuring temperature directly using two- or four-wire RTDs.eight8Need greater switching capacity?Choosing the right switching solution is often crucial to ensuring highmeasurement integrity and productivity in production testing.Keithley’s Applications Engineers can help you determine the mostappropriate configuration for your application.If your application requires more than ten channels of switchingcapacity, consider Keithley’s Series 2700 Integramultimeter/data acquisition/switching systems. The 80-channel Model 2700 and Model 2701 mainframes offer theindustry’s lowest per-channel installed cost in highperformance data acquisition and control packages. A built-inEthernet interface in the Model 2701 makes it the best choicefor distributed applications. With five module slots, the Model2750 simplifies configuring solutions for applications withhundreds of channels. A choice of 12 plug-in modules makesIntegra systems almost infinitely adaptable.Series 7000 switching solutions complement Series 2000 DMMswhen building multi-point test systems. The 80-channel Model7001 High Density Switch System will accept a widevariety of switching cards for signals up to 2GHz.Similarly, the Model 7002 Switch Mainframe willsupport up to 400 channels or crosspoints, with aunique interactive channel status display. Bothmainframes are compatible with Keithley’s line ofmore than 40 Series 7000 Switching Cards.The two-slot Model 7002-HDSwitch Mainframe combinesthe channel density of the Model 7002with the half-rack footprint of the Model 7001.Two new high density switch cardsmainframe let you create a system with upto 384 matrix crosspoints or 320multiplexer channels.9nineVisit or call your local office for more information on our other switching solutions (p. 9). ten1011elevenSpecifications are subject to change without notice.All Keithley trademarks and trade names are the property of Keithley Instruments, Inc.

利用吉时利高功率系统数字源表®源测量单元（SMU）仪器对功率半导体器件进行测试概述电子控制与电子功率转换在各行业(如发电、工业马达驱动与控制、运输及IT) 发展迅速，正推动着功率半导体器件设计与测试的增长。

为了证明技术改进，必须对新器件与现有器件能力进行对比。

非硅半导体材料的使用需要采用新工艺，而且，为了可持续发展，这些新工艺必须能够交付已知的结果，并具有高产量。

随着新器件设计的发展，必须对诸多器件进行更长周期的可靠性测试。

因此，测试工程师必须找到具有高精度、可扩展和高费效比的测试设备。

功率模块设计工程师——分布式功率半导体器件用户——正致力于半导体器件测试工作。

为了开发DC-DC转换器、逆变器、LED控制器、电池管理芯片以及诸多其他器件，他们在设计中采用分立半导体器件。

为了实现更高的电源效率，他们必须对来自供应商的器件进行质量检验，确保其符合应用环境的要求，并预测器件对功率模块效率的影响，最后验证最终产品的性能。

吉时利源测量单元（SMU）仪器，可为器件测试工程师及功率模块设计工程师提供测量所需的工具。

不论他们对曲线跟踪仪、半导体参数分析仪或示波器是否熟悉，都能简单而迅速地得到精确的结果。

本应用笔记介绍了某些最常见的测试、相关挑战以及吉时利源测量单元（SMU）仪器怎样简化测量流程，特别是与吉时利参数曲线跟踪仪配置进行集成时。

功率器件特性分析背景开关电源是电源管理产品中使用的常见电子电路。

在最简单的开关电源（图1）中，其主要组成包括半导体（如功率MOSFET）、二极管和一些无源元件（包括电感和电容）。

许多开关电源还包括变压器，用于实现输入和输出之间的电子隔离。

半导体开关和二极管以受控的占空比轮流导通和关断，生成期望的输出电压。

在对电源效率进行评估时，理解开关损耗（在器件改变开关状态的短暂时间内出现的能量损耗）和导通损耗（当器件处于开启或关闭状态时出现的能量损耗）非常重要。

基于吉时利源测量单元（SMU）仪器的解决方案，可以帮助测试工程师对影响传输损耗的器件参数进行评估。

环境条件进行校准程序要求的环境条件：•环境温度23°C±5℃，•相对湿度低于80％，除非另有说明。

预热时间K2000型万用表进行校准之前至少预热一个小时。

如果仪器已受到极端温度（上一节中所述的范围之外），需要另外的额外时间以便使仪器的内部温度稳定。

通常情况下，每超出规定的温度范围10℃（18℉），需要另外增加一个小时的稳定时间。

此外，测试设备也需要按制造商所指定的最低时间进行预热。

电源要求：K2000型万用表需要100V/120V/220V/240V±10％，频率45赫兹到66赫兹或360赫兹到440赫兹的交流电源。

校准注意事项：当执行校准程序时：•确保适当预热设备，并连接到相应的输入插孔。
