+# gain_viz
+
+**gain_viz** is a Python-based web application for adjusting RF gain settings and visualizing their effect in real-time. It integrates with USRP and SCM devices, providing live IQ time-series and spectrum visualization.  
+
+---
+
+## Features
+
+- Adjust **USRP Tx/Rx gains** and **SCM Tx/Rx gains** from a web interface.  
+- Live IQ **time-series plot** in milliseconds.  
+- Live **spectrum visualization** (waterfall / spectrogram).  
+- Fast refresh for near real-time feedback.  
+- Responsive and clean web interface built with HTML/CSS/JS.  
+
+
+
+## Installation
+
+Make sure you have **Python 3.8+** installed.
+
+1. Clone the repository:
+
+```bash
+git clone https://riahub.ai/gael/gain-viz.git
+cd gain-viz
+```
+
+2. Build and install
+
+```bash
+pip install --upgrade build
+python3 -m build
+pip install dist/gain_viz-0.1.0-py3-none-any.whl
+export PATH=$PATH:~/.local/bin
+source ~/.bashrc
+
+
+```
+
+## Usage
+
+Run the application
+```bash
+gain_viz
+```
+
+Open your browser at http://localhost:5000
+
+
+- Toggle the gain switches to enable input fields.
+- Enter new gain values and press Update Gains.
+- Observe the effect on the time-domain IQ plot and spectrum.
