: Features independent "Vertical Position" and "Scale" knobs for both Channel 1 and Channel 2, along with a Math button for operations like FFT, addition, and subtraction.

The interface is divided into several dedicated control areas for intuitive navigation:

The is a budget-friendly, ultra-thin 2-channel digital storage oscilloscope featuring a 110MHz bandwidth and a 1GSa/s real-time sampling rate . It is widely used by hobbyists and engineers for its compact design, 7-inch high-definition color display, and versatile measurement functions. Key Technical Specifications Bandwidth Channels Sampling Rate 1 GSa/s (500 MSa/s per channel) Display 7-inch TFT LCD, 800 x 480 pixels Storage Depth 10K sampling points Vertical Sensitivity 5 mV/div to 5 V/div Time Base Range 2 ns/div to 1000 s/div Operational Guide & Controls

: Always calibrate your probes before use. Connect the probe to the BNC input and the built-in compensation pin (usually 1kHz square wave) and adjust the probe's trimmer capacitor until the waveform is perfectly square.

: Includes a "Horizontal Scale" knob for the time base and a "Horizontal Position" knob to adjust trigger placement.

: Used to select menu items or set specific values when a symbol appears on the screen.

: To maintain accuracy, the DOS1102 supports a self-calibration routine. Disconnect all probes and select "Self-Calibration" from the utility menu; the process typically takes a few seconds.

: Supports Edge and Video trigger types with Auto, Normal, and Single modes. The "Trigger Level" knob adjusts the voltage at which the scope captures the signal.
