 # SDG2042X-PyQt-GUI-for-Linux
 
 A simple cross‑platform (Linux tested) GUI for controlling the **Siglent SDG2042X** function generator over LAN.
+
+## Features
+- Connect via LAN (raw SCPI over TCP, port 5025)
+- Basic waveform setup (SINE, SQUARE, RAMP, PULSE, NOISE, ARB, DC)
+- Control frequency, amplitude, offset, and phase
+- Output ON/OFF toggle
+- Burst configuration (mode, cycles, delay, trigger source)
+- Sweep configuration (linear/log, start/stop frequency, time, direction)
+- ARB Manager (not fully tested yet):
+  - List built‑in and user waveforms
+  - Upload `.bin` or `.csv` waveforms to USER memory
+  - Download USER waveforms from the generator
+  - Set selected waveform to active channel
+
+## Requirements
+- Python 3
+- PyQt5 (`pip install pyqt5`)
+
+## Usage
+```bash
+python3 sdg2042x_gui.py [options]
+```
+
+### Options
+- `-ip <addr>` or `--ip <addr>` : Prefill IP address field
+- `-h` or `--help` : Show help
+
+Example:
+```bash
+python3 sdg2042x_gui.py -ip 192.168.1.120
+```
+
+## Notes
+- Tested with Siglent SDG2042X firmware supporting SCPI commands.
+- Communication uses SCPI over TCP/IP; no VISA or NI libraries required.
+- ARB file formats: use Siglent EasyWaveX to prepare `.bin`/`.csv` if needed.
