Control any GPIB instrument through conversation — multimeters, oscilloscopes, power supplies, signal generators.
Get Started Tool Reference

22 Tools

Four tool categories covering the full stack: bridge management, bus operations, instrument interaction, and low-level diagnostics.

Multi-Bridge

Connect serial, TCP, and WiFi bridges simultaneously. Run cross-bus workflows with concurrent access across independent GPIB buses.

Zero-Config Discovery

Auto-scan buses on connect. Instruments are identified via *IDN? and registered for immediate use. No manual address mapping required.

Safety-Aware

Per-bridge locking prevents bus collisions. Configurable inter-command delays protect against ESP32 brownout. Init sequences enforce deterministic state.
