Function Generator Capabilities

• Standard waveforms (sine, square, triangle, sawtooth, noise)
• Configurable parameters (frequency, amplitude, duration)
• Test signal injection for calibration and testing
• Dual-channel output simulation

MCP Integration

• 9 MCP tools for instrument control and analysis

Architecture

The server uses a modular TypeScript architecture with:

• Hardware Interface Layer: Abstracts simulation and real hardware
• Signal Processing Engine: FFT, filtering, and analysis algorithms
• MCP Server Core: Exposes functionality through MCP protocol
• Data Store: Handles acquisition storage and caching
• Measurement Engine: Automated parameter analysis
• Protocol Decoders: Digital communication analysis

Quick Start (Windows + Claude Desktop)

Prerequisites

• Windows 10/11 with working microphone
• Node.js (version 18 or higher)
• Claude Desktop

Installation

1. Clone and install

   git clone https://github.com/oscilloscope-mcp/oscilloscope-mcp.git
   cd oscilloscope-mcp
