在研发实验室中，371A用于表征功率器件的新设计，提取SPICE参数，故障分析和数据表生成。
在制造测试中，371A用于验证设备质量和过程监控。
371A用于进站检查，以验证功率设备的性能并执行故障分析。
可以从功能齐全的前面板或通过GPIB进行所有测量的交互式控制。可以使用多种存储方法来调整，存储和调用操作参数，包括371A非易失性存储器，内置MS DOS兼容软盘或外部控制器。
371A提供三种光标测量模式。点光标可在任何点上直接显示屏幕上的电压，电流，gm或DC beta值。Window光标可以放置在两条曲线之间以测量小信号beta或gm，也可以用于可视化通过/不通过测试。功能线光标提供斜率或截距值的屏幕读数。
在扫描测量模式下，371A将自动构建一系列曲线，同时以低占空比脉冲激励设备。借助此功能，可以显示功率曲线，而不会使设备过热。
测试夹具是标准附件，可提供安全的设备外壳，以确保操作人员在测量期间得到保护。该测试夹具可容纳标准的A1001至A1005适配器（带开尔文感应），3针适配器（无开尔文感测）以及A1023和A1024表面安装适配器。
Tektronix 371A, the industry leader in high power curve tracers, is used for testing a wide variety of power semiconductors. It performs DC parametric characterization of thyristors, SCRs and power MOSFETs.
The high voltage collector mode permits testing the Off-characteristics of a device up to 3,000 volts. The pulsed high current collector mode provides output current pulses greater than 400 amps peak for testing On-characteristics. It also permits high power testing up to 3,000 watts.
In the R&D lab, the 371A is used for characterization of new designs of power devices, extraction of SPICE parameters, failure analysis and data sheet generation.
In manufacturing test, the 371A is used to verify device quality and process monitoring.
The 371A is used for incoming inspection to verify power device performance and perform failure analysis.
Interactive control of all measurements can be done from the full featured front panel or over the GPIB. Operating parameters can be adjusted and stored and recalled using several storage methods including the 371A nonvolatile memory, the built-in MS DOScompatible floppy disk or to an external controller.
The 371A provides three cursor measurement modes. The Dot cursor provides direct screen readout of voltage, current, gm or DC beta at any point. The Window cursor can be positioned between two curves to measure small signal beta or gm, and can also be used for visual go/no-go tests. The Function Line cursor provides screen readout of a slope or intercept value.
In the sweep measurement mode, the 371A will automatically construct a family of curves while stimulating the device with low duty-cycle pulses. With this capability, power curves can be displayed without excessive heating of the device.
A test fixture is a standard accessory that provides safe device enclosure to ensure operator protection during measurements. The test fixture accommodates standard A1001 through A1005 adapters with Kelvin sensing, 3-Pin adapters without Kelvin sensing and the A1023 and A1024 surface mount adapters.
