ArbWave30 – 30MHz 任意波形发生器 | FPGA + 高速DAC | SCPI 可控

方波满幅输出波形: > 当前版本方波有约 13.5% 的过冲,为滤波器群延时特性所致,后续将通过优化通道设计解决,详见重构滤波器调试笔记。

经上图数据可计算出[^1]: THD ≈ -60.2 dBc @10MHz, SFDR[^2] ≈ 63.26 dBc @10MHz

[^1]: 由于示波器自身产生的谐波不可忽略,该值仅供参考,实际值需频谱分析仪复测。

[^2]:SFDR 分为两种定义:1、含谐波;2、不含谐波。由于表中没有非谐波分量,故采用第一种定义。

当前你可以浏览 docs/ 中的设计文档,了解详细的技术规格和设计思路; 或查看 hardware/ 中的原理图和 PCB 设计文件与 firmware/ 中的代码框架,了解硬件与软件的构成,并提出您的宝贵意见。

这意味着: - 你可以自由使用、修改、分享固件代码,但任何衍生代码也必须以 GPL-3.0 开源。 - 你可以基于硬件设计文件制作、分发物理设备,但必须同时开源你对设计文件的修改,并保留署名。 - 你可以复制和修改文档,但必须同样以 CC BY-SA 4.0 分享,并注明原作者。

Control board: common questions

What microcontroller does the Control board use?

The Control board is built around the STM32F411CEUx, from the STM32 family.

How big is the Control board?

The Control board measures 100 × 90 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Control board?

134 components, from 56 distinct parts. The full bill of materials is listed on this page.

Where can I download the Control board design files?

From the EERNINUO/ArbWave30 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Control board design in my own project?

Yes, under the terms of its GPL-3.0 license, which EERNINUO chose for the repository.

Can I test firmware for the Control board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
