Description

Ultra-portable Touchscreen Oscilloscope powered by DreamSourceLab ——————————————————————————————DSTouch has the same hardware architecture as desktop oscilloscopes, with a powerful FPGA waveform processing engine and high-speed DRAM storage, which is totally different from MCU-based solutions.1 Compared with MCU-based solutions, DSTouch can achieve Large Storage Depth and High Waveform Refresh Rate. What are the differences between MCU-based oscilloscopes and DSTouchWhat are the differences between MCU-based oscilloscopes and DSTouch For a MCU-based oscilloscope (200MSa/s sample rate and a depth of 128K), maacquisition time at 200MSa/s is only 0.5ms + 10Hz screen refresh rate. The total waveform window time within 1 second is 0.5ms 10 = 5ms.This kind of performance gap is difficult to discern simply from technical specifications, leading to many mixed-quality products in the market. DSTouch DS4T212 has a maacquisition time of 10ms at 200MSa/s With a fixed 60Hz screen refresh rate The total waveform window time within 1 second is 10ms 60 = 600ms.2. Bandwidth and Sampling Rate Bandwidth refers to the signal frequency at which the amplitude response of the analog front-end circuit drops to -3dB for a sine wave.Taking the example of the DS4T212, with a nominal bandwidth of 70M, when a sinusoidal sweep signal ranging from 0 to 100M is inputted it can be observed that the entire frequency range is displayed correctly, with a smooth decrease in amplitude. 70MHz bandwidth DSTouch can still trigger and display 92MHz sine wave signal stably, but according to the -3dB calculation, its bandwidth is still only 70MHz. DSTouch oscilloscopes mark the true real-time sampling rate, instead of confusing the audience with equivalent sampling rates.DSTouch oscilloscopes mark the true real-time sampling rate, instead of confusing the audience with equivalent sampling rates.Square wave is a good way to test the real-time sampling rate, and many low-end oscilloscopes cannot display high-frequency square waves correctly. DSTouch provides multiple interpolation methods to perfectly restore high-frequency square waves.——————————————————————————————————————————————– Storage depth is also an obstacle that low-end oscilloscopes cannot overcome, and it is one of the three most important indicators of oscilloscopes, which seriously affects the actual waveform restoration effect. How to confirm the real storage depth of an oscilloscope? This can be tested using an amplitude-modulated signal with a high carrier frequency (low-frequency envelope, high-frequency carrier). Only oscilloscopes with a sufficient storage depth can correctly capture both the envelope and the high-frequency carrier.Below is a test using a 300Hz amplitude-modulated 10M carrier signal. You can use this signal to verify the storage depth specification of your oscilloscope. Oscilloscopes with insufficient storage depth will not be able to capture such signals.The low-end version of the DSTouch oscilloscope has a storage depth of up to 2Mpts, which is even larger than the depth of some desktop oscilloscopes. And it maintains the same storage depth at full horizontal resolution. The signal captured by DSTouch oscilloscope can be zoomed in or out horizontally after stopping, perfectly reproducing the desired waveform.Lissajous figure in X-Y mode.DSTouch uses EPSON high-precision low-temperature drift crystal oscillator and hardware real-time frequency measurement. A oscilloscope that cannot measure millivolt-level signals is a toy, not a tool.DSTouch can be used to measure tiny signals at the millivolt level, supporting 20MHz bandwidth limitation, is the best tool for power ripple analysis.DSTouch has a minimum vertical sensitivity of 10mv/div, and excellent low noise performance.DSTouch has good input protection, with a voltage input range of up to u00b1200V.
