The following tests were conducted to ensure the integrity of the update:

When the lab lights hummed awake at 07:30, Jun poured a final cup of coffee and sat at the bench where his Owon HDS2102S oscilloscope waited. It had been a dependable instrument for three years: 20 MHz, dual-channel, the little white scope that had caught more flaky circuits than he could count. Today it had a job that felt small but mattered — verify a firmware update that promised a subtle but crucial fix to channel-trigger timing.
The official Owon upgrade utility runs exclusively on Windows (7, 10, or 11).
: The GitHub project "owowon," an alternative PC-based UI for the HDS series, has been successfully developed and tested exclusively with the HDS2102S running official firmware version V1.5.1 . This confirms that the V1.5.1 file from OWON is functional and can be used as a base for development work.
A 50 MHz signal at the 2ns/div setting incorrectly spanned 8 divisions (16ns period), showing inaccurate data.
If you are currently experiencing specific issues with your oscilloscope, I can help you troubleshoot. Could you tell me: What is displayed in your System menu? What specific symptoms or bugs is your scope showing?
Ensure the firmware you downloaded explicitly matches your hardware revision (e.g., V1.x vs V2.x). Step 2: Download and Install the Official USB Drivers
The most critical thing to verify is this: Owon does not universally recommend updating the firmware on every
: A user on the EEVblog forum received a new HDS2102S with V4.3.0 but found only V1.5.1 on the support page. The community quickly identified that the major version numbers indicate different hardware revisions , confirming the firmware files are not interchangeable . A direct query to OWON support on this matter resulted in a clear statement: " There is not latest firmware version for HDS2102S on our website, don't upgrade any of firmware. "
Once complete, the software will display a "Success" or "Upgrade Completed" dialogue box. Step 5: Post-Update Validation and Calibration
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
