scope

A command for connecting to supported oscilloscopes, capturing or reading waveforms, measuring them, and saving results as CSV files or plots. An oscilloscope is a device that displays changing electrical signals.

In plain words
What is it for?
Use it with Rigol instruments over SCPI, or with exported CSV files from the DS100 handheld oscilloscope, to detect devices, measure signals, parse data, and create plots.
Why use it?
It reduces manual waveform inspection when investigating voltage, frequency, timing, or other signal problems.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scope scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

命令: /ea scope (示波器)

功能

两条路径:

A. Rigol 示波器实时 SCPI —— 抓取 + 测量,排查模拟波形/电压/频率。 已真机验证:DS1074Z(DS1000Z 系列)。DS2000A 系列(如 DS2302A)命令集通用,但电压换算公式需真机复核(DS2000A 坐标系统不同,见注意事项)。

能力 参数 底层 依赖
波形抓取 --capture :WAV:DATA? + TMC 解析 pyvisa + pyvisa-py
电压/时间轴还原 --capture (val-128)/25*vdiv+voffs + :WAV:XINC? numpy
直接测量 --measure vpp,freq,... :MEAS:ITEM? pyvisa
CSV / PNG --save / --plot numpy + matplotlib + matplotlib
设备识别 --detect *IDN? pyvisa
无硬件自测 --parse-tmc <file> 合成 TMC 块走解析链路 numpy 即可

SCPI 基本通用,主流品牌(Siglent/鼎阳/泰克等)命令集大同小异,换设备只需调 --resource

B. 正点原子 DS100 手持示波器(无 SCPI,U 盘导出 CSV) —— 手动导出波形后解析分析。

能力 参数 底层 依赖
导出 CSV 波形解析 --parse-ds100 <file.csv> 跳过 header/自动探测列 + numpy 测量 numpy 即可
采样率自动提取 --parse-ds100 正则解析 header sampling rate : N numpy
频率/周期/占空比 --parse-ds100 过中值上升沿检测 + 阈值占比 numpy
波形出图 --plot matplotlib + matplotlib

DS100 限制:不支持 SCPI、无官方 PC 软件,USB 仅作 U 盘(卷标 ATK-DSO)。只能在示波器上按 M → Save → CSV 导出原始采样,再用本命令解析。

真机格式(已实测 999.CSV):单行 header CHA(V) probe:X5,sampling rate : 10000,后接单列电压值(每行一个,100000 点)。脚本自动从 header 提取采样率(10kHz)与探头倍率(x5),无需手动指定。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scope is a command published in the GitHub repository jzl-maker/EA-SKILL (4 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,616 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
