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

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

handheld oscilloscope has an established firmware update process that resolves critical bugs, most notably fixing a display timing issue where a 2ns/div setting previously showed incorrect waveforms. Verified Update Procedure

Updating the firmware involves putting the device into a "Mass Storage Class" (MSC) mode so a computer can recognize it as a removable drive.

Preparation: Download the correct firmware file (e.g., Scope.upp) specifically for your model from the Owon Download Center. Enter Upgrade Mode: Power on the device. Press the System button and navigate to System > Upgrade Establish PC Connection: Connect the to your PC via a USB-C cable. In the system menu, toggle the USB setting to MSC. Transfer & Install:

The device will appear as a removable disk on your computer. Copy the firmware file to this disk.

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.

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). Safety Precautions

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

is a task that requires careful verification of your current hardware and software versions, as updates are not cross-compatible across different main version branches. Key Firmware Facts & Verified Issues

Version Compatibility: If your scope has a version starting with V4.x.x, you can only update to other V4 versions. Attempting to use V1.5.1 or V2.0.4 on a V4 unit will fail and potentially brick the device.

Resolved Display Bug: Earlier units (pre-V1.51) had a display discrepancy where the 2ns/div horizontal range showed incorrect timing (actually 2.5ns/div). This was verified to be fixed in firmware V1.51.

Availability: Official downloadable updates for V3 and V4 branches are often not public. OWON support has occasionally advised users with these versions not to attempt updates unless a specific bug is present.

New Features: Recent updates (such as V4.7.1+) have introduced Ampere units for vertical measurements, useful for clamp meter users, and renamed certain commands (e.g., SQR to RMS). Verified Update Procedure

According to user reports and technical guides, the upgrade process follows these steps:

Check Version: Navigate to the System menu on the HDS scope and select System (F2) to view your current version.

Enable USB Mode: In the System menu, set the USB mode to MSC (Mass Storage Class).

Transfer File: Connect the device to a PC. A removable disk will appear. Copy the .upp firmware file (e.g., Scope.upp) directly to the root of this disk.

Execute: Power the scope off and back on. The device will automatically run the upgrade and shut down when finished. Where to Find Files

Official Portal: Check the OWON Download Center for the latest general releases.

Community Archives: For older or specific version branches, the EEVblog forum and GitHub archives are the primary sources for verified firmware files.

VERIFICATION REPORT

Device: OWON HDS2102S Status: Firmware Update Verified Date: [Current Date]

Step 5: Post-Update Checks (Did it work?)

After the reboot, go to Utility > System Info.

Confirmed fixes in the latest build (v20240820):

  • ✅ FFT responsiveness: No more 10-second lag when switching bands.
  • ✅ Multimeter logging: The PC connection no longer drops randomly.
  • ✅ Chinese/English toggle: No more half-translated menus.

One regression: The battery percentage indicator seems slightly jumpy (20% -> 45% instantly). This is cosmetic.

Step 3: The "Unplug to Update" Sequence

Do not power on the scope normally.

  1. Power off the HDS2102S completely.
  2. Insert the USB drive.
  3. Press and hold the "F1" button (leftmost softkey).
  4. While holding F1, press the Power button.
  5. Keep holding F1 for 5 seconds, then release.

What you should see: A white text bootloader menu appears (not the normal blue waveform screen).

Step 4: Verification

The update takes about 90 seconds.

  • Good: You will see "Erasing... Writing... Verifying... PASS"
  • Bad: "File not found" (check the owon folder name) or "CRC Error" (bad download).

Once it says "PASS", power cycle the device normally.

OWON HDS2102S Firmware Update: A Verified Walkthrough (No Bricking Allowed)

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.

Verification

  • Verify Update: After the update process is complete, restart your device if prompted. Then, go back to the settings or system information menu to verify that the firmware has been updated to the latest version.
