This is especially useful when you're trying to analyze infrequent events or capture long bursts of data. With 14 Mpts of memory, you can zoom in on specific sections of your waveform without losing resolution. This gives you a ton of flexibility when it comes to analyzing complex signals. Another great feature is the 7-inch color display. The large display makes it easy to see all four channels simultaneously, and the color coding helps you distinguish between the different signals. The display is also bright and clear, even in brightly lit environments. This is a significant improvement over older oscilloscopes with smaller, monochrome displays. The SDS1104X-E also includes a built-in function generator. This is a handy feature that allows you to generate various test signals, such as sine waves, square waves, and ramp waves. The function generator can be used to stimulate your circuits and test their response. This can be incredibly useful for troubleshooting and verifying the performance of your designs. Finally, the SDS1104X-E has a variety of triggering options. Triggering allows you to synchronize the oscilloscope's display to a specific event in your circuit. This is essential for capturing stable and repeatable waveforms. The SDS1104X-E supports a wide range of triggering modes, including edge triggering, pulse triggering, and logic triggering. This gives you the flexibility to trigger on just about any type of signal. Overall, the Siglent SDS1104X-E offers a comprehensive set of features and specifications that make it a great choice for a wide range of applications. Whether you're a hobbyist, student, or professional, this oscilloscope has something to offer.
