Verified Firmware Updates for the OWON HDS2102S Updating the firmware on the OWON HDS2102S
handheld oscilloscope is a critical maintenance step that can resolve hardware-level display bugs and improve measurement accuracy. However, unlike standard consumer electronics, these updates are highly hardware-specific and require careful verification to avoid bricking the device. Why Update? Key Fixes and Improvements
The most significant verified fix in recent firmware versions (such as ) addresses a major horizontal display discrepancy Original Issue
: In the 2ns/div range, graticules were incorrectly spaced, leading to inaccurate frequency readings (e.g., a 50 MHz signal appeared as 16ns instead of the correct 20ns). Verified Fix
: Version 1.5.1 corrected this scaling, ensuring that 50 MHz signals are properly timed across the 10-division display. Performance Stability For Devices Using an SD Card :
: Newer firmware versions also improve digital trigger robustness and hysteresis settings, making the device more reliable in electrically noisy environments. Critical Pre-Update Verification
Before attempting an update, you must verify your specific hardware version. OWON uses different firmware tracks for different manufacturing batches, and they are not cross-compatible Check Current Version
: Navigate to the "System" menu to find your current firmware string. Major Version Lock : If your device is on a
track, it can only be updated to other V4 versions. You cannot "downgrade" to V1 or V2 tracks, nor can older V1 hardware typically use V4 firmware. Hardware Compatibility
: Certain older models use a "Gigadevice" with OTP (One-Time Programmable) SecureRom that may be physically non-upgradable. Verified Update Procedure
If you have confirmed a compatible update is available from the official OWON Download Center , follow these verified steps: Software Prep : Download the Launcher.exe or update tool provided in the firmware package. Driver Installation : Connect the
to your PC via USB. Ensure the USB drivers are correctly identified in your PC's Device Manager Enter Update Mode Set the USB mode to in the device's system menu. Some versions require copying a file (e.g.,
) directly to the device's root directory while it is mounted as a removable disk. Other versions use the PC software to put the device into bootloader mode
by turning it off and then on while the software is "waiting".
: Once the progress bar finishes, the device will typically reboot automatically. Press on the device to confirm and finalize the installation. Important Safety Warning Official OWON support has occasionally advised users not to upgrade
if no specific issue is being experienced, stating that the latest versions for certain serial numbers may not be publicly posted. If your device is functioning correctly and does not show the 2ns/div display bug, it is often safer to remain on the factory-installed firmware. or locate the exact firmware file based on your device's serial number?
To verify and potentially update the firmware of an OWON HDS2102S device, follow these steps. Note that specific steps may vary depending on the device's model and the firmware version you are updating to. Always refer to the official OWON documentation or support resources for the most accurate and detailed instructions.
