# Overview

`instro` provides high-level, vendor-agnostic interfaces for common lab
instruments. Each instrument type defines a standard API that works across multiple hardware vendors.

| Class | Description |
| --- | --- |
| [`InstroDAQ`](https://dev.nominal.io/instro/ref/instruments/daq.md) | Data acquisition systems |
| [`InstroDMM`](https://dev.nominal.io/instro/ref/instruments/dmm.md) | Digital multimeters |
| [`InstroPSU`](https://dev.nominal.io/instro/ref/instruments/psu.md) | Programmable power supply units |
| [`InstroELoad`](https://dev.nominal.io/instro/ref/instruments/eload.md) | Electronic loads |
| [`InstroScope`](https://dev.nominal.io/instro/ref/instruments/scope.md) | Oscilloscopes |
| [`InstroFlowController`](https://dev.nominal.io/instro/ref/instruments/flowcontroller.md) | Flow Controllers |
| [`I2CInterface`](https://dev.nominal.io/instro/ref/instruments/i2c.md) | I2C bus communication devices |
| [`InstroAWG`](https://dev.nominal.io/instro/ref/instruments/awg.md) | Arbitrary waveform generators |
| [`InstroSDR`](https://dev.nominal.io/instro/ref/instruments/sdr.md) | Software defined radios (unstable) |

Each instrument page includes the interface, configuration types, driver base classes,
and vendor-specific driver implementations. Errors raised by instrument methods are
documented in [Exceptions](https://dev.nominal.io/instro/ref/library/exceptions.md).

## Supported devices

The table below is included verbatim from the repository README, so the two can’t drift.

The Modbus and EtherNet/IP rows are covered under [Protocols](https://dev.nominal.io/instro/ref/protocols.md).
Community-contributed drivers are documented in the
[instro-contrib guide](https://dev.nominal.io/instro/library/contrib.md) rather than this reference.
