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.

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

⚠️ Important notes from my verification:

Do not interrupt power during the update
Re-calibrate the probes and self-cal after updating (Settings → Self Cal)
User data/saved waveforms were not lost, but backup is still wise

🔁 Rollback possible? The official update tool does not support downgrading to older firmware versions, so update only if the fixes apply to your use case.

Updating the firmware on an Owon HDS2102S requires extreme caution because hardware versions (HW) and serial numbers dictate compatibility. Attempting to install the wrong version can permanently brick your device. Critical Pre-Check

Before attempting any update, you must identify your current version and hardware:

Check Current Version: Navigate to the System or About menu on your device to find your current firmware (e.g., V1.x.x, V2.x.x, V4.x.x). Verify Compatibility:

Firmware versions are not interchangeable across mainboard versions. For example, a V1.x.x unit cannot be upgraded to V2.x.x.

Updates often depend on specific serial number ranges (e.g., 2152xxx). How to Perform the Update

If you have verified a compatible file from an official or verified source:

Download Official Files: Visit the Owon Download Center and filter by the HDS200 Series and Latest Firmware. Prepare the USB Drive: Format a USB flash drive to FAT32.

Copy the firmware file (usually ending in .bin or .upd) to the root directory of the drive. Do not put it in a folder. Initiate Update: Power off the device. Connect the USB drive using the provided adapter cable.

Power the device on. Depending on your version, it may auto-detect the file or require you to navigate to System > Update.

Wait for Completion: Do not power off or disconnect the device during the process. The unit will typically restart once finished. Important Warnings

Manufacturer Advice: Owon has occasionally advised users via email not to upgrade if the current firmware is stable, as some units ship with the latest supported version for their specific hardware.

Verified Fixes: Firmware version 1.51 is known to fix specific display discrepancies at the 2ns/div horizontal range.

Support: If you cannot find a version matching your serial number on the website, it is highly recommended to email Owon Support with your model and serial number to request the correct file.

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. 🔧 OWON HDS2102S – Verified Firmware Update Available

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

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.

1. Executive Summary

The firmware update for the OWON HDS2102S Handheld Digital Storage Oscilloscope has been successfully applied and verified. The device is now operating on the target firmware version with all core functions (oscilloscope, multimeter, and signal generator) confirmed operational.

Step 2: The "Hidden" File System Trick

Here is where most people fail. You cannot just drag and drop the .bin file onto a large USB drive.

The verified method:

Format a USB 2.0 drive (4GB or 8GB max) to FAT32. ExFAT/NTFS will fail silently.
Create a folder on the root of the USB drive named: owon
Inside the owon folder, place the firmware file: HDS200_20240820.bin
Crucially: Rename the file to hds200.bin (lowercase). The bootloader is case-sensitive.

Final USB path: E:\owon\hds200.bin
