About SCPIRef

SCPIRef is a free, browser-based reference platform built for RF and measurement automation engineers. It brings together SCPI command databases for popular test instruments alongside practical RF engineering calculators — all in one place, without requiring a login or installation.

Why SCPIRef?

Writing test automation scripts means constantly hunting through hundreds of pages of instrument programming manuals. SCPIRef aggregates that information into a fast, searchable format with Python + PyVISA code examples ready to copy — so you can focus on writing the test, not finding the command.

What's on the Site

SCPI Command Reference — Searchable command tables for Keysight and other manufacturers, organized by category with parameter descriptions and examples.
RF Calculators — Browser-based tools for dBm↔Watt conversions, VSWR/Return Loss, and more. No server, no sign-up.
Equipment Comparison — Side-by-side spec comparisons for common RF test instruments.
Automation Guides — Practical guides for Python + PyVISA test automation workflows.
