Dso2512g Firmware 'link' Review

The most interesting "hidden" feature in the Zeeweii/SigPeak DSO2512G firmware is its undocumented overclocking mode, which allows you to manually widen the sample rate for better performance on higher frequency signals.  Notable Firmware Features 

• V1.0.5: Stable, but lacks signal generator advanced features.
• V1.1.0: Introduced FFT improvements. Some users report slower UI.
• V1.1.2: Widely considered the "Goldilocks" version—stable, fast, and all features working.
• V1.2.0 (Beta): Adds new triggers. Not recommended for professional use.
