SCPI Examples for Test & Measurement Equipment

A collection of Python examples demonstrating how to control and interact with test and measurement equipment using SCPI (Standard Commands for Programmable Instruments) commands.

Overview

This repository contains practical examples for automating and controlling various test and measurement instruments. Currently focused on oscilloscope control, the examples demonstrate common tasks and best practices for instrument automation.
