FeelTech FY2300 20M Arbitrary Waveform Tools

Python tools for working with the FeelTech FY2300 20M function / arbitrary waveform generator.

This repository currently includes three main components:

1. fy2300_serial.py
   A Python serial library for controlling the FY2300 through ASCII commands validated with real hardware.

2. fy2300_gui_simple_v3.py
   A simple Tkinter GUI that lets users:

   • configure common waveforms,
   • adjust frequency, amplitude, offset, and duty cycle,
   • select 0 dB / 20 dB attenuation,
   • load an arbitrary waveform from an oscilloscope CSV file,
   • upload it to the FY2300 using arb2.

3. EMISION_SintReal_fy2300_RUIDO.py
   A functional example that takes a real segment from SDS00004.csv, adds controlled white noise, and uploads it as an arbitrary waveform.

Motivation

When working with existing FeelTech-related repositories, we found that arbitrary waveform data upload did not correctly solve our specific use case for the FY2300 20M, especially when trying to reproduce a real waveform measured with an oscilloscope.

For that reason, this project was built around a workflow that was actually validated in the lab:

• arbitrary waveform upload through upload_waveform(...),
• playback through arb2,
• frequency, amplitude, offset, duty, attenuation, and trigger control from Python,
• and a simple GUI so that other users can reuse the tool without editing the scripts directly.

Requirements

• Python 3.10+
• numpy
• matplotlib
• pyserial

Installation:

pip install -r requirements.txt

Quick start

1) GUI

python fy2300_gui_simple_v3.py

The GUI allows you to:

• test COM port communication,
• configure a common waveform on the main channel (CH1),
• load a signal segment from a compatible CSV file,
• upload it as arb2,
• preview the waveform locally before sending it to the instrument.

2) Real waveform example

python EMISION_SintReal_fy2300_RUIDO.py

This script:

• reads SDS00004.csv,
• extracts a time segment,
• adapts it to 2048 points,
• adds mild white noise,
• uploads it as an arbitrary waveform to the FY2300.

Important notes

• The current implementation is focused on the main channel (CH1).
• Instrument attenuation directly affects the observed output amplitude.
  Always verify whether the generator is set to 0 dB or 20 dB.
• The library was built for a specific workflow validated with real hardware, not as a universal wrapper for every FeelTech model.
• Before using this software with laboratory equipment, read DISCLAIMER.md.

---

Suggested future improvements

• formal CH2 support,
• GUI presets,
• reading current instrument parameters,
• packaging as an installable Python module,
• automated tests with bench hardware.
