How should we judge the performance of an oscilloscope?

An important application of an oscilloscope is as a tool for debugging problems. Therefore, the ability to quickly find abnormal events is an important criterion for evaluating the performance of an oscilloscope. The GDS-1042 series digital storage oscilloscope is a general-purpose 40MHz, 2-channel oscilloscope designed for the education market and general maintenance work. The user-friendly operation interface and the entire series use an A+ grade 5.6” TFT color display, which not only provides high-definition image quality, but also has a wide viewing angle that can quickly and accurately identify the measurement signal when observing the waveform.

GDS-1042 Digital Storage Oscilloscope Features:

1. 250Msa/S real-time sampling rate;

2. 25GS/s equivalent sampling rate;

3. Up to 10ns peak detection;

4. 5.6-inch color TFT display;

5. Store and call settings and waveforms;

6. Automatic measurement of 19 sets of parameters;

7. Multi-language menu;

8. Mathematical operations: addition, subtraction, FFT;

9. Edge, video, pulse width trigger;

Digital oscilloscopes have unique advantages such as waveform triggering, storage, display, measurement, and waveform data analysis and processing, and their use is becoming increasingly popular. Due to the large performance difference between digital oscilloscopes and analog oscilloscopes, if used improperly, large measurement errors will occur, thus affecting the test task.

With the development of electronic technology, digital oscilloscopes have greatly expanded their working capabilities with digital technology and software. The shortcomings of early products such as low sampling rate, large dead time, and low screen refresh rate have been greatly improved. Modulated signals, communication eye diagrams, video signals and other composite signals that were previously difficult to observe are becoming easier to observe. Digital oscilloscopes can calculate and analyze data, and are particularly suitable for capturing all the details and abnormal phenomena generated in complex dynamic signals. Therefore, they have been widely used in scientific research and industrial production. In order to make the digital oscilloscope work in a qualified state, it is an urgent task for test engineers to regularly, quickly and comprehensively calibrate the oscilloscope to ensure its traceability.
