Required Software & Files:
HDS2102S_Vx.x.x.upd or HDSpkg.bin.CertUtil in Windows).If you own an OWON HDS2102S—the handy 2-in-1 handheld oscilloscope & multimeter—you know it’s a solid piece of kit for field work and low-voltage debugging. However, like any Chinese test equipment, the stock firmware can be buggy (slow FFT, weird trigger behavior, or language glitches).
I recently went through the process of updating the firmware on my HDS2102S. Spoiler: It worked perfectly.
Here is the verified process I used, including the pitfalls to avoid.
Do not power on the scope normally.
What you should see: A white text bootloader menu appears (not the normal blue waveform screen).
The mini CD that came with your scope is likely outdated. Do not use it.
Go directly to the OWON website (owon.com.cn) or their official AliExpress store page. Note: OWON’s site navigation is terrible. Search for “HDS2102S” directly.
As of this post, the verified stable version is: HDS200_20240820.bin (Size: ~2.3MB). Always check the date stamp.
The firmware update for the OWON HDS2102S is VERIFIED SUCCESSFUL. The device is cleared for operational use.
Verified by: [Your Name/Title] Signature: ____________________
The Owon HDS2102S firmware update is a critical maintenance step primarily used to resolve a known horizontal display bug at the 2ns/div time base. However, official firmware distribution is strictly tied to specific hardware revisions and serial numbers, meaning there is no "universal" latest version for all units. Key Verified Fix: 2ns/div Display Issue
Reviewers have verified that updating to at least version 1.5.1 (for compatible hardware) fixes a significant scaling error:
The Bug: A 50 MHz signal at the 2ns/div setting incorrectly spanned 8 divisions (16ns period), showing inaccurate data.
The Verified Fix: After the update, the same signal correctly spans 10 divisions for a full waveform (20ns period), aligning with the true 50 MHz frequency. Critical Warning: Firmware Compatibility
Do not attempt to flash any firmware found online without first verifying your unit's current version and hardware generation.
Version Locking: Units running V1.x, V2.x, V3.x, or V4.x are generally not compatible with each other. For example, if your unit has V4.3.0, you cannot "upgrade" it with V1.5.1 or V2.0.4 files.
Hardware Changes: Older units used Gigadevice flash chips that are often non-upgradable due to hard-coded checksums, while newer units (hardware V3.0+) use Macronix chips that support updates.
Official Stance: Owon has occasionally advised users via email not to upgrade if no version is specifically listed for their serial number on the Owon Download Center. Verified Update Methods
Two primary methods have been documented by the community for the HDS200 series: Mass Storage (MSC) Method: Set the USB mode to MSC in the system menu.
Connect to a PC; the scope will appear as a removable drive. Copy the Scope.upp firmware file to the root directory. Restart the device to trigger the automated update. Bootloader/Tool Method:
Uses specialized flashing software provided by the manufacturer (often found on Onetech).
Requires manual installation of USB drivers and putting the device into bootloader mode by cycling power while connected to the PC. Known Firmware Versions OWON HDS 200 Handheld Oscilloscope w/ builtin DMM/AWG

Power the scope Off and then back On. It will automatically install the update and shut down once finished.
Verification: Power on the device and check the version number in the System menu (e.g., version 1.5.1 or later) to confirm success. Key Benefits of Updating
Accuracy Fix: Corrects graticule spacing at high speeds (2ns/div), ensuring signals like 50 MHz are displayed with the correct period.
Enhanced Features: Newer versions (such as v4.7.1+) have been noted to include or improve features like RMS measurements and "auto" button stability.
Stability: Bug fixes for CSV file exports and system-level crashes reported in earlier versions.
Note: Always match the firmware to your device's specific serial number range, as some hardware revisions may not be compatible with all firmware versions.
Updating the firmware on your Owon HDS2102S handheld oscilloscope is a critical maintenance step to resolve known display bugs and unlock new measurement features. Using a verified update process ensures you don't accidentally "brick" the device by using incompatible files. Why Update Your HDS2102S? Preparing for the Firmware Update Before you start
Recent verified updates address specific hardware-software synchronization issues that affected early units:
Timebase Accuracy: Fixed a prominent bug where the 2ns/div horizontal setting incorrectly displayed a 50 MHz signal as having a 16ns period instead of 20ns.
Enhanced Measurements: Newer versions like V4.7.1 and above have introduced RMS measurements and added vertical units in Amperes, which is particularly useful for users working with clamp meters.
Trigger Stability: Fixed 2-channel trigger bugs that occurred when using multiple inputs simultaneously. Verified Firmware Versions (2024-2025)
The HDS200 series uses different hardware branches. You must match your update to your current Main Version Number found in the System menu.

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.,
