Product 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.

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.

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.

--------------------------------------------------------------------------------------------------------------------------------------------

1

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.

1

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.

1

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.

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.

1

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 ±200V.

This scope uses an FPGA + Arm microcontroller combo and excellent memory depth to achieve truly remarkable performance. The boot time is nearly instantaneous, the touch screen and intuitive layout make usage a breeze, and the wave display is superbly fluid and accurate, with the end result being a tiny beast of an instrument. There are several good articles and other info on the web about these that are worth checking out. Highly recommended!

DSTouch DS4T1012 model.Astonishingly good. Actually does what it says.Been researching affordable high performace little scopes for years, so finally bought this one.My first digital scope that outperforms my old textronix 100MHz CRT scope.Real specs without the hype.Just nitpicking, wish the XY mode was more versatile, good for lissajous patterns, not a curve tracer.Grid matrix very dim, like in the photos, but the cursors conveniently give you vertical and horizontal precision digital measurements without eyeballing per division.5 stars.
