Additionally, you can access the function through this menu. FFT converts a time-domain signal into its frequency components. This is invaluable for detecting audio distortion, Analyzing power supply noise, or inspecting harmonic frequencies in switching circuits. Saving Data to a USB Drive To save waveforms for a lab report or remote diagnosis:
Forces a trigger event regardless of whether the signal meets the trigger criteria. This is helpful for examining DC signals or unknown waveforms. Initial Setup and Probe Calibration
Choose your storage type: (binary waveform data), Setup (scope settings), or Picture (PNG/BMP screenshot). Select the target directory and press Save . Troubleshooting Common Issues
Once synced, you can use the software to take high-resolution screenshots for lab reports, print data waveforms, or export raw CSV data points into software like Microsoft Excel or MATLAB for advanced mathematical plotting. 8.

A: The DOS1102 is the standard 2-channel digital oscilloscope. The DOS1102S model is an upgrade that includes a built-in, fully integrated arbitrary waveform generator, turning it into a 2-in-1 test and measurement device. For a detailed comparison, it is best to review the dedicated manual and specification sheet for each model. Additionally, you can access the function through this menu

The Hanmatek DOS1102 allows you to export screenshots and data matrices via its rear USB device port. Software Installation Saving Data to a USB Drive To save
Attach the hook tip of the probe to the "Probe Comp" terminal (usually a small metal loop on the bottom right of the front panel providing a 5V, 1kHz square wave). Connect the alligator ground clip to the ground terminal loop.
Connect the probe to the terminal, a small metal pin usually near the bottom right, which outputs a known square wave signal. Use the AutoSet button to get a stable waveform. Then, use the provided adjustment tool (a small plastic screwdriver) to turn the trimmer screw on the probe until the square wave's corners are perfectly sharp and flat, without any rounding or overshoot.
