Overview

R.A.M.F. Diagnostic is a Chrome browser extension designed to monitor and diagnose satellite set-top boxes on a local internal network. It connects to the device via its IP address and provides real-time SNR (Signal-to-Noise Ratio) measurements, spectrum analysis, and detailed transponder reports — all from within the browser.

The extension is intended for use by satellite technicians and enthusiasts who want a convenient, browser-based diagnostic interface for the SR-525HD device.

Installation

Since this extension is not published to the Chrome Web Store, it must be loaded manually as an unpacked extension.

1. Download or clone this repository:

   git clone https://github.com/Csnyi/RAMFstbDiagnostic.git

2. Open Chrome and navigate to:

   chrome://extensions/
   

3. Enable Developer mode (toggle in the top-right corner).

4. Click “Load unpacked” and select the root folder of this repository (the one containing manifest.json).

5. The extension will appear in your Chrome toolbar.

---

Usage

1. Connect — Enter the IP address of your SR-525HD device and click the Connection button. The extension will attempt to connect to the device on your local network.
2. Spectrum Report — Once connected, select a satellite from the list and click Create Report to start a full transponder scan. The results are displayed as interactive CNR and RSSI charts.
3. SNR Measurement — Switch to SNR mode, enter the transponder parameters (frequency, symbol rate, polarization, LNB settings, DiSEqC port), and optionally set a measurement duration in minutes. Click Start to begin live SNR monitoring. Click Stop to end the measurement.
4. Export — After a measurement, export the collected data to JSON (for later re-import) or directly to an Excel file.
5. Load Saved Reports — Use Open JSON to load a previously exported report and re-view the charts and data tables.

Note: If no measurement duration is set, the SNR measurement runs until you manually stop it with the Stop button.
