Firmware for the HDS2102S is strictly hardware-version bound. OWON HDS 200 Handheld Oscilloscope w/ builtin DMM/AWG To update the firmware on your Owon HDS2102S
The Owon HDS2102S is a highly popular 3-in-1 handheld device, combining a 100MHz oscilloscope, a multimeter, and a waveform generator into one portable unit. However, staying up to date with the latest firmware updates is essential for maintaining accuracy and unlocking new features.
Updating your device can resolve specific technical issues, such as the widely reported 2ns/div display discrepancy, where older firmware versions incorrectly spaced graticules at high-speed horizontal ranges. Essential Preparation Before Updating
Before attempting a firmware flash, you must identify your device's specific hardware revision. Firmware versions for the HDS200 series are not universal; they are strictly tied to specific serial number ranges and hardware versions.
Check Your Current Version: Navigate to the System menu on your scope to find your current firmware (e.g., V1.5.1 or V4.7.1).
Hardware Compatibility: Versions starting with the same number (e.g., V4.x.x) can typically only be updated to other versions within that same "V4" branch.
Manufacturer Warning: Some hardware revisions, specifically those with older flash chips like "Gigadevice," may have read-only OTP ROM and are considered "NOT upgradable". Step-by-Step Update Guide
The Owon HDS2102S uses a Mass Storage Class (MSC) method for updates, making it relatively straightforward if you have a PC.
