Two Measurement Modes: Digitizing or Integrating Precisely characterize transient and steady-state behavior, including rapidly changing thermal effects,with the two measurement modes in the Model 2657A. Each mode is defined by its independent analog-to-digital (A/D) converters. The digitizing measurement mode provides speeds up to 1μs per sample. The dual 18-bit digitizers allow you to capture voltage and current transients simultaneously. In the integrating measurement mode, the dual 22-bit integrating analog to digital converters allow more precise measurement of voltage and current. Two A/D converters are used with each measurement mode, one for current and the other for voltage, that run simultaneously for accurate source readback that does not sacrifice test throughput.   Expansion Capabilities Through TSP-Link® technology, the Model 2657A can be linked with other Series 2600A instruments to form a larger integrated system with up to 32 nodes. Precision timing and tight channel synchronization are guaranteed with built-in 500ns trigger controllers. The fully isolated, independent channels of the SourceMeter instruments make true SMU-per-pin testing possible. High Power Device Test Fixture The Model 8010 High Power Device Test Fixture provides safe and easy connections for testing packaged high power devices at up to 3000V or 100A. The Model 8010 provides connections for a high voltage SourceMeter instrument (Model 2657A), one or two high current SourceMeter instruments (Model 2651A), and three low power SourceMeter instruments (other Series 2600A or Model 4200-SCS SMU instruments). This allows devices with two terminals (diodes) or three terminals (transistors) or even four or five terminals to be characterized safely and accurately. The Model 8010 has full interlock capability for up to six SourceMeter instruments. The Model 8010 has integrated protection circuits that protect the low voltage SourceMeter instruments from high voltages the Model 2657A can output should a device fault occur. The Model 8010 includes both a high current (100A) and a high voltage (3000V) test socket. Various replacement test socket modules are available, including TO-247, TO-220, axial lead, and a blank socket module that allows building a custom socket. In addition to standard banana jumpers, the Model 8010 has rear-panel scope and thermal probe ports to simplify system integration.   *Keithley’s Chinese Website：http://www.keithley.com.cn/    

The Model 2657A is a high voltage, high power, low current source measurement unit (SMU) instrument that delivers unprecedented power, precision, speed, flexibility, and ease of use to improve productivity in RD, production test, and reliability environments. The Model 2657A is designed specifically for characterizing and testing high voltage electronics and power semiconductors, such as diodes, FETs, and IGBTs, as well as other components and materials in which high voltage, fast response, and precise measurements of voltage and current are required. The Model 2657A joins Keithley’s Series 2600A family of power semiconductor characterization and test solutions to offer the highest power and best low current performance in the industry. These custom-configurable solutions are supported by the industry’s most powerful parametric characterization software platforms to grow with you as your applications evolve.   The Model 2657A, like every Series 2600A SourceMeter instrument, offers a highly flexible, fourquadrant voltage and current source/load coupled with precision voltage and current meters.

4200- PIV 包 无需重新布线或切换，可以给 DUT 引脚提供直流和脉冲能力。这种能力的关键是4200-RBT远程 偏置 T 型接头 ，它采用无源电器元件将低频直流信号和高频脉冲信号相结合。 4200-RBT的连线是SMA同轴电缆，它将连接到很多RF和直流探针设备上。 直流探针互连 对于直流结构，内含的适配器电缆（ 4200- PRB -C ，图14）将SMA转换为直流设备上的双SSMC连接。     图14.     4200-PRB-C 4200脉冲SMA至SSMC的Y适配器 许多探头设备在探针支架上是 SSMC 的连接 Cascade DCM- 2xx开尔文直流探头设备 Suss  Microtec的探头尖端 Signatone SCA- 50的同轴探头 美国探测及技术 74CJ系列同轴探头支架 靠近探头尖部，为SSMC接头的任何探针互联系统 这些SMA至SSMC“Y”适配器电缆适合于以直流结构标称的晶圆上的 脉冲 IV 测试 。这些“Y”电缆不适于更高频率的设备。没有指定频率的上限，这是因为实际设备和探头的配置对测试会有显著的影响。一般情况下，当使用直流探头连接和 4200- PRB - C 电缆时，任何高于1GHz Ft的设备可能会发生振荡。   射频探针互连 如果设备是射频布局（G-S-G），那么“Y”适配器电缆和直流探针设备很可能不够用。 在 RF G-S-G 焊盘布局的情况下，不使用4200-PRB-C “Y”电缆，只需使用4200-PIV包提供的较短的SMA电缆（6寸/15厘米），用此电缆会直接将 4 200-RBTs 与RF设备（下文中图16）相连。请注意，具有功率分配器的4200 -RBT连接到门极。   图16.     远程偏置T型接头至RF的RF G-S-G的脉冲IV连接   了解更多信息  要想了解有关4200-PIV脉冲IV包或者吉时利其他系列数字源表的更多信息，请点击 http://www.keithley.com.cn/products/dcac/voltagesource/?mn=4200-PIV ，或登录 吉时利官方微博 （ http://weibo.com/keithley ）与专家进行互动。 4200-PIV包http://www.keithley.com.cn/products/dcac/voltagesource/?mn=4200-PIV DUT http://www.keithley.com.cn/events/proddemos/27xxdemo/demoimages/PD1_DUT.jpg/view 4200-PRB-C http://www.keithley.com.cn/products/semiconductor/parametricanalyzer/4200scs/?mn=4200-PRB-C 双SSMC至SMA电缆http://www.keithley.com.cn/products/dcac/waveform/?path=4200-PRB-C/RELPRD_4200-PRB-C 4200-PIV  http://www.keithley.com.cn/products/dcac/voltagesource/?mn=4200-PIV
