我们经常谈论的是，尽管Digilent的便携式仪表设备are commonly used in professional environments, originally these tools were created for education. Our founders wanted a way to let every single student see the signals in their systems anytime they needed, while not necessarily being confined to the lab. This way students could learn on their schedule and accelerate discovery. This also helped supplement the time needed in the dedicated lab, while strengthening the practical knowledge base of students through hands-on experimentation.
在继续致力于教育的同时，我们还花费了10多年的时间来添加功能并增长我们的仪器软件工具集，波形，使其更适用于专业用户。在过去的几年中，我们通过介绍了这项努力波形活软件，以及通过引入硬件中的这项工作Digital Discovery，各种适配器，以及OpenScope MZ。这可能会使学者可能感到困惑。所以今天我要去硬件is right for whichclassroom。
Course: Analog Circuits
硬件：这模拟发现
在整个模拟电路课程中，学生将需要各种工具，其中许多工具可以在模拟发现。最常使用的可能是示波器工具，可以查看他们将要学习的电路和组件的输出。此外，他们将需要一个波形生成器来为这些电路提供输入。尽管模拟发现的主要连接方式是飞丝，加上BNC Adapter，可以使用传统探针，并且范围的带宽增加到30MHz。
When students move on to designing filters, the traditional method of obtaining the frequency and amplitude response can be used to demonstrate the process. In addition, the Network Analyzer provides the ability to sweep the frequency range and automatically plot these responses, which significantly decreases iteration time.
这模拟发现2还提供了一个基本的电力供应和电压表,for when -5V to +5V power and simple voltage measurements are needed.
课程：FPGA设计/数字逻辑
硬件：数字发现
During a student’s time in an FPGA design course, they will learn theory, design and analysis methodologies, and apply this knowledge to a variety of FPGA designs. Naturally, part of this process includes failure and iteration. So students can simulate their designs, however, even then there will be timing and other factors that won’t be seen in simulation. TheDigital Discoveryprovides a Protocol Analyzer, Logic Analyzer, and Pattern Generator in one tool gives students the opportunity to view the signals in their designs at any point in the design process, not just through simulation. Seeing the signals, and viewing the decoded data, creates the opportunity to decrease the unnecessary barriers to understanding the problem and decrease time spent iterating on the design. The Digital Discovery also provides sample rates of up to 800 MS/s, up to 32 Channels, and selectable logic level, making it a more versatile Digital Design tool than the same instruments on the Analog Discovery.
课程：芯片和嵌入式控制的系统
硬件：数字发现
For the same reasons that theDigital Discovery是FPGA设计和嵌入式开发的正确选择，它是芯片课程中系统的绝佳选择。让学生有机会查看其设计中的信号并将代码连接到实际行为，从而更深入地了解概念和设计。
Course: Embedded Systems
这俩模拟发现和Digital Discovery是本课程的好候选人。两者都合并了逻辑分析仪，该仪为学生提供了观看和分析显示时间，协议和电动机信号的机会。此外，他们都有一个协议分析仪，用于模拟UART，I2C，SPI和CAN信号，以及用于生成已知输入的模式生成器。
这choice between the two depends on a number of factors. Does the course also require analog instruments, which are available on the Analog Discovery? Or does the course require a higher sample rate than 100MS/s, which the Analog Discovery can provide?
If leaning toward the Digital Discovery, make sure to check if the course requires selectable logic levels and other settings found on the Digital Discovery when making your decision. Additionally, one must take into consideration if the course requires more channels than the 32 found on the Digital Discovery.

这模拟发现’s Oscilloscope and WaveForm Generator tools can be used to analyze an approximated impulse response, as well as the step response of a system, and demonstrate convolution. The Spectrum Analyzer on the Analog Discovery can be used to visualize the spectrum of various periodic signals in order to compare expected results based on computation.

这WaveForm Generator on the Analog Discovery can be used to supply known inputs to the control system in order to test its design. In addition, the Network Analyzer provides a quick way to view the frequency response (transfer functions) for characterization and comparison to theoretical models.
Overall, the Analog Discovery can also be used in many additional upper-division courses. To read more about its use in these courses, check out本文在Asee发表。
如上所述，Digilent的便携式仪表线中的每个设备都包含许多提供其台式功能功能的工具。总共，模拟发现提供了13个仪器，数字发现提供了5个以更高规格的数字仪器。This makes them great devices for student-owned instrumentation, as well as flipped classrooms and remote learning.This can effectively increase the availability of classroom spots to students, and remove unnecessary situational barriers to learning.
