: Attach your probe to the signal source. Always connect the ground clip to the circuit ground first.

The DOS1102 features a USB port on the front. You can save screenshots (BMP) or waveform data (CSV) directly to a flash drive for reports or further analysis on a PC. Math Functions: hanmatek dos1102 manual
: Check the CH1/CH2 menu and ensure the software probe multiplier matches your physical probe switch setting (1X vs 10X). Factory Reset (Self-Calibration)
Triggering is often the most misunderstood concept in oscilloscopes, and the DOS1102 manual provides several modes to stabilize waveforms. : Attach your probe to the signal source
The is a highly popular, budget-friendly 2-channel digital storage oscilloscope [1]. It features a 110 MHz bandwidth and a 1 GSa/s sampling rate [1].
Press the button on the top right of the panel. The scope will automatically configure the timebase and voltage to show a clean square wave. Examine the shape of the square wave on the screen: You can save screenshots (BMP) or waveform data
Controls the time base (sec/div) and horizontal position.
button to access a menu of 30+ automatic measurements, including Frequency, Peak-to-Peak Voltage ( cap V sub p p end-sub ), RMS, and Duty Cycle. Cursor Measurements: For manual precision, press
So open the cover and let the screen glow. The manual is not just instructions; it’s a small atlas to the invisible. Follow its maps, tune its colors, and you’ll find that each waveform is a sentence, and every measurement, a sentence understood.
