+# NQRduck Module: Spectrometer LimeNQR
+This module is a part of the NQRduck project. It is a submodule of the [spectrometer module](https://github.com/nqrduck/nqrduck-spectrometer) for the NQRduck project. It is designed to be used with the [NQRduck](https://github.com/nqrduck) project.
+
+The module provides a Graphical User Interface (GUI) for the control of the LimeSDR based spectrometer. It is designed to be used with the NQRduck project. The GUI is based on the [PyQt5](https://pypi.org/project/PyQt5/) library
+
+The  original code for the control of the LimeSDR based spectrometer was part of the paper by A. Doll; Pulsed and continuous-wave magnetic resonance spectroscopy using a low-cost software-defined radio. AIP Advances 1 November 2019; 9 (11): 115110. https://doi.org/10.1063/1.5127746. More information about the original code can be found in the [LimeDriver](https://github.com/nqrduck/limedriver) project.
+
+The currently supported LimeSDR devices are:
+- LimeSDR Mini v2.0 (probably also v1.x, but not tested)
+- LimeSDR USB
+
+## Installation
+
+###  Requirements
+- [LimeSuite](https://wiki.myriadrf.org/Lime_Suite)
+- [HDF5](https://www.hdfgroup.org/solutions/hdf5/)
+
+You can find more information about the installation of dependencies in the [LimeDriver](https://github.com/nqrduck/limedriver) project.
+
+Additional dependencies should be installed  by the pyproject.toml file when installing this module.
+
+## Setup
+To install the module you need the NQRduck core. You can find the installation instructions for the NQRduck core [here](https://github.com/nqrduck/nqrduck).
+
+Ideally you should install the module in a virtual environment. You can create a virtual environment by running the following command in the terminal:
+```bash
+python -m venv nqrduck
+```
+
+You can install this module and the dependencies by running the following command in the terminal:
+```bash
+pip install .
+```
+
+## Usage
+The module is used together with the NQRduck [pulseprogrammer](htpps://github.com/nqrduck-pulseprogrammer) module.
+
+
+### Notes
+- When using the LimeSDR USB use the TX Matching: 0 and RX Matching: 0 for  frequencies below  1.5GHz in the settings of the module. 
+- For the LimeSDR Mini 2.0 use the TX Matching: 2 and RX Matching: 2 for frequencies bellow 1.5GHz.
