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
: 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?
Upgrading the firmware on the Owon HDS2102S is a precise process that can resolve significant performance issues, such as the widely documented 2ns/div display discrepancy. However, proceed with caution: Owon support often advises against updates unless you are targeting a specific fix, as newer firmware is strictly hardware-version dependent. Verified Firmware Fixes
Horizontal Scale Fix: Updating to v1.5.1 or higher resolves a bug where 50 MHz signals displayed incorrectly at the 2ns/div range. owon hds2102s firmware update verified
Measurement Units: Recent updates (e.g., v4.7.1) have added the ability to display vertical units in Amperes, which is helpful when using current clamp meters. Before You Start: Compatibility Check
You must match your firmware version precisely to your hardware. Updating with an incompatible file can lead to "Upgrade Error 4" or a bricked device.
Check Version: Navigate to System > System > Page 2 > About on your device. Version Chains:
If you are on v1.x.x, you can typically only upgrade to other v1.x.x versions.
If you are on v4.x.x, updates often transition from v4.1.0 toward v4.7.1 or v4.9.0. Verified Update Procedure
Download Official Files: Visit the Owon Download Center and search for your specific HDS200 series model.
Enable MSC Mode: Connect your scope to a PC via USB. On the scope, go to System > USB and select MSC (Mass Storage Class). The device will appear as a removable drive.
Transfer File: Copy the firmware file (e.g., Scope.upp) directly to the root of the removable drive.
Initiate Flash: Power the scope off and then back on. The device will automatically detect the file, perform the upgrade, and shut down once finished.
Verify: Power it back on and check the version number in the System menu. Community Tools & Alternatives
Owowon UI: For users looking for faster data acquisition (up to 100 readings per second), the Owowon GitHub project offers a custom Windows interface tested specifically with HDS2102S v1.5.
Historical Archive: Community-maintained hardware and firmware logs can be found on GitHub by fuho, detailing board dates and specific serial number ranges for safe matching.
If you'd like, let me know your current firmware version or the hardware date from your system menu, and I can help you verify if a specific update like v1.5.1 or v4.7.1 is safe for your unit.
The Owon HDS2102s firmware update improves trigger stability, signal generator performance, and multimeter speed, with updates best sourced from the official website. Essential pre-update steps include maintaining a 70% battery charge and using a data-capable USB-C cable to connect to a PC in storage or software update mode.

has received critical acclaim as a budget-friendly 3-in-1 handheld tool, particularly after a verified firmware update resolved a notorious display bug. Earlier versions suffered from an incorrect graticule spacing at the 2ns/div horizontal setting, which made a 100 MHz signal appear as 125 MHz. Verified Firmware Improvements
The most significant verified fix came with version 1.51, which corrected the 2ns/div display issue. Subsequent updates like v4.7.1 have further enhanced the device by adding RMS measurements and fixing dual-channel trigger bugs. Performance & Usability Review Multimeter & Generator: The Verified Firmware Updates for the OWON HDS2102S Updating
integrates a 20,000-count DMM and a 25 MHz arbitrary waveform generator (AWG), both of which are highly rated for their accuracy.
Portability: Users frequently cite its battery-powered nature as a major advantage for field work, such as HVAC maintenance or on-site embedded system troubleshooting.
Hardware Sensitivity: Unlike some competitors, Owon's firmware updates are strictly tied to specific hardware versions. Attempting to flash firmware meant for a different PCB version (e.g., v2.20 vs. later models) can brick the unit. Community Feedback
