For users looking to extend the functionality of the HDS2102S, a community-driven software called is available. It acts as a much faster external PC-based user interface for the oscilloscope, capable of acquiring data at a significantly higher rate (up to 100 readings per second) than the official OWON software. It was specifically tested working with the HDS2102S on firmware version 1.5.1. : Certain older models use a "Gigadevice" with

He reloaded his saved configuration, which restored channel labels, probes, and measurement presets. He ran a quick sanity check: a 1 kHz square wave from the function generator into Channel 1, channel 2 tied to ground. The trace was steady, measurements matched the generator to within expected tolerance, and trigger behavior looked normal.
