The SCPI Reference
Engineers Actually Need
Cross-manufacturer SCPI command database, RF engineering calculators, and PyVISA automation guides — all in one place.
Everything in One Place
No more hunting through 500-page PDFs or vendor-specific tools.
RF Calculators & Converters
Browser-based tools that run entirely client-side. No sign-up, no delay. Built for RF and microwave engineers who need fast, accurate results.
SCPI Command Reference
Searchable SCPI command tables for popular instruments — Keysight, Tektronix, Rigol, and more. Each command includes parameters, return values, and ready-to-run Python + PyVISA code.
Equipment Spec Comparison
Side-by-side specification tables for oscilloscopes, DMMs, power supplies, and more. Compare bandwidth, sample rate, memory depth, and price before you buy.
Test Automation Guides
Step-by-step guides for building multi-instrument test systems with Python and PyVISA. Covers GPIB, USB-TMC, and LAN connections across Windows, Linux, and macOS.
The Gap Nobody Filled — Until Now
Vendor tools like Keysight IO Libraries and TekVISA only support their own instruments. Manufacturer manuals are 500-page PDFs. And there's no independent site that lets you search and compare SCPI commands across manufacturers — until SCPIRef.
