Unlike open-source scopes (e.g., Rigol hacked firmware), the DSO2512G firmware is closed-source and only provided by FNIRSI.
Measurement comparisons show that with custom firmware, the -3dB point moves from 12MHz to over 17MHz. Some users achieve 20MHz by replacing input capacitors physically, but the firmware removes software-imposed filtering.
Lower the baud rate in your flashing software and try again.
: While marketed at 120MHz, expert testers on EEVblog suggest the effective bandwidth is closer to 35-40 MHz with standard probes. dso2512g firmware
Fine-tunes the automatic measurement readouts (Vpp, Vmax, Frequency, Duty Cycle) to reduce error margins. Prerequisites: What You Need Before Updating
(Note: I can also fetch related search-term suggestions to help refine what you need.)
Understanding is essential for users looking to fix bugs, improve UI performance, add features, or customize the waveform generator capabilities. This article serves as a comprehensive guide to the DSO2512G firmware ecosystem. 1. What is the DSO2512G Firmware and Why Update? The firmware is the internal operating system running the Unlike open-source scopes (e
: Use the "Normal" trigger mode to keep the last captured signal on the screen when pressing the Stop button. If you'd like, I can help you: Draft a specific post for a forum like EEVblog or Reddit.
Disconnect all probes and run the "Self-Calibration" routine from the system menu. Driver missing or bad cable.
This can sometimes be triggered by pulling specific pins (like CS on the SPI flash) low during startup, allowing you to rewrite the flash memory via USB. 📈 Optimization Tips Lower the baud rate in your flashing software and try again

Adding cursor measurements for screenshots, math functions, and generating waveform CSV files for external analysis.
Press and hold the designated update button combination (on most DSO2512g revisions, this involves holding down the or "AUTO" button while sliding the power switch to ON ).
The firmware update was supposed to fix the FFT roll-off. Instead, it had introduced something strange: a single anomalous sample that appeared only at 3:17 AM UTC, Channel A, 10x probe, 50 ms/div. A spike that shouldn’t exist—yet persisted across power cycles, battery pulls, and even a full eMMC reflash.
The most interesting "hidden" feature in the 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
