# About

The **nirfmx-python** repository generates Python bindings (Application Programming Interface)
for interacting with the RFmx Products.

**nirfmx-python** follows [Python Software Foundation](https://devguide.python.org/#status-of-python-branches)
support policy for different versions.

## RFmx WLAN Generation Python API Status

| Item                         | Details                      |
|------------------------------|-------------------------------|
| **Driver Version Tested**    | [2026 Q3](http://www.ni.com/downloads/)                      |
| **Supported Python Versions**| Python 3.9+ (64-bit)    |
| **Documentation**            | [RFmx WLAN Generation Docs](https://nirfmx-python-nirfmxwlangen.readthedocs-hosted.com/en/latest/) |


## Documentation

You can find the latest API documentation for the **nirfmx-python** package
on [Read the Docs](https://nirfmx-python-nirfmxinstr.readthedocs-hosted.com/en/latest/)

Refer to the [RFmx User Manual](https://www.ni.com/docs/en-US/bundle/rfmx/page/user-manual-welcome.html)
for an overview of RFmx, system requirements, troubleshooting, key concepts, etc.


## Operating System Support

**nirfmx-python** supports Windows systems where the supported drivers are 
installed. Refer to [NI Hardware and Operating System Compatibility](https://www.ni.com/r/hw-support) for 
which versions of the driver support your hardware on a given operating system.


## Installation

You can use [pip](http://pypi.python.org/pypi/pip) to download [nirfmxwlangen](https://pypi.org/project/nirfmxwlangen/) and install it.
    
    $ python -m pip install nirfmxwlangen

To also install gRPC support for remote NI gRPC Device Server communication:

    $ python -m pip install "nirfmxwlangen[grpc]"

## Upgrade

You can use [pip](http://pypi.python.org/pypi/pip) to upgrade [nirfmxwlangen](https://pypi.org/project/nirfmxwlangen/) package using following command:

    $ python -m pip install nirfmxwlangen --upgrade


## License

This project is licensed under the MIT License. While the source code is not publicly released,
the license permits binary distribution with attribution.

**Note:** This Python driver depends on several third-party components that are subject to separate
commercial licenses. Users are responsible for ensuring they have the appropriate rights and licenses
to use those dependencies in their environments.


# gRPC Features

For driver APIs that support it, passing a GrpcSessionOptions instance as a parameter to nirfmxinstr.Session.__init__() is subject to the NI General Purpose EULA.


# SSL/TLS Support

The server supports both server-side TLS and mutual TLS. Security configuration is accomplished by setting the `server_cert`, `server_key` and `root_cert` values in the server's configuration file. The server expects the certificate files specified in the configuration file to exist in a `certs` folder that is located in the same directory as the configuration file being used by the server. For more detailed information on SSL/TLS support refer to the [Server Security Support wiki page](https://github.com/ni/grpc-device/wiki/Server-Security-Support).


## Support and Feedback

For support with Python API, hardware, the driver runtime or any other questions,
please visit [NI Community Forums](https://forums.ni.com/).

## Numpy array size handling in RFmx APIs

The numpy arrays are passed in pre-allocated. If the pre allocated array size does not match the actual array size returned by the measurement, the array is automatically resized to fit the data, which may invalidate the previously created view. Passing an empty array (size 0) is fine; it will be resized as needed.
