該設計分享的是Digilent同軸適配器板（BNC Adapter Board），該BNC 適配器是一個簡單的插件板，主要與Digilent Analog Discovery 2配合使用，您可以使用標準BNC測試終端接口與袖珍示波器探頭聯(lián)合使用。該BNC 適配器板分別提供兩個示波器通道，交流耦合和直流耦合。

同時附件內(nèi)容“相關文件”分享了口袋式示波器 BNC 適配器板課程，課程大概內(nèi)容如下：
課程主要介紹如何快速起步上手使用Analog Discovery這款可支持LabVIEW的口袋式虛擬儀器產(chǎn)品。包括如何借助WaveForm軟件來配置AD，以及如何利用AD各類強大的口袋儀器功能來構建和測試模擬數(shù)字電路。
口袋式示波器 BNC 適配器板更多介紹如下：
Each channel of the oscilloscope can be selected as AC or DC, coupled by adjusting the jumper that is located behind that channel’s BNC input connector. In addition, the two AWG channels are equipped with BNC terminations, and each channel can have either the 50-ohm or the 0-ohm termination selected. This enables the user to match the Analog Discovery’s output impedance with standard 50-ohm test leads or to be directly tied to the lead. Additionally, the adapter board takes the oscilloscope bandwidth from 9 MHz (wire harness) to 30 MHz on the Digilent Analog Discovery 2.
Features:
- Allows the use of standard BNC-terminated test leads and probes on your Analog Discovery
- Selectable AC and DC coupling to oscilloscope probes
- Selectable 50-ohm or 0-ohm output impedance on arbitrary waveform generator (AWG) channels
- With the Discovery BNC, the differential scope inputs of the Analog Discovery become single-ended with the negative input connected to the ground
