-# 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.
