A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides.
The input analogue signal is sampled and then converted into a digital record of the amplitude of the signal at each sample time. The sampling frequency should be not less than the Nyquist rate to avoid aliasing. These digital values are then turned back into an analogue signal for display on a cathode ray tube (CRT), or transformed as needed for the various possible types of output—liquid crystal display, chart recorder, plotter or network interface.
1) Siglent Technologies SDS1052DL
SDS1000DL+ is a dual-channel universal digital oscilloscope, available in 50 MHz bandwidth. It includes a 32 kpts memory depth that helps to ensure accurate waveform resolution and to capture longer signal lengths. With its 7 inch TFT-LCD (800*480) screen, there is adequate screen space to help better see and analyze waveform details. Along with a 500 MSa/s sampling rate, the SDS1000DL+ supports 32 parameters measurements and common mathematical operations to speed up complex / repetitive measurements.
All specification applies to 10X probe and All the SDS1000DL Series Digital Storage Oscilloscopes. To verify that the oscilloscope meets specifications, the oscilloscope must first meet the following conditions:
● The oscilloscope must have been operating continuously for thirty minutes within the specified operating temperature.
● You must perform the Do Self Cal operation, accessible through the Utility menu, if the operating temperature changes by more than 5° C.
● The oscilloscope must be within the factory calibration interval
