#Sainsmart oscilloscope software#

In the software thereвЂ™s a decode feature for I2C.

I believe I need a different probe to truly see the microstepping on the oscilloscope. They allow for quieter operation and better prints by extending the 16 steps to 256 micro steps. The drivers can be upgraded to Trinamic stepper drivers. Typically they come with inexpensive A4988 stepper drivers. They have a voltage spike and dip.ДЄs you guys know I do a lot with 3D printing. The nice looking square wave is not as nice as I thought. I played around with all the buttons and knobs and drilled down and found this. I then hit reset and auto and software greeting me with this waveform.

Next thing I did was breakout my Arduino UNO and wrote a little code to test with:ДЇirst I set the proper probe setting. I ended up taking a sharpie and labeling the probes. It took a minute to figure that the A probe is farthest away from the calibrating terminal.

#Sainsmart oscilloscope manual#

I got the software and manual from the SainSmart wiki. I started by reading the included manual and found it is strictly for the probe. I was only able to play back exactly what I recorded. IвЂ™m not sure what recording format it is I was assuming it was going to be a text file and record everything. Once the measurements were recorded I could open and play, or I could step through the frames. I was not able to stop a recording once it started. It has the ability to record in the top right. Then we have the time knob and voltage knobs for channel A and B.

Test impulse response of filters and systems.

Characterize noise in DC power supplies.

Measure harmonic content and distortion in systems.

Using the FFT math function on a time domain signal provides the user with frequency domain information and can provide the user a different view of the signal quality, resulting in improved measurement productivity when troubleshooting a device-under-test. There are a variety of uses that can benefit from viewing the frequency spectrum of a signal. What is the FFT (Fast Fourier Transform) math function of an oscilloscope useful for? All of them seemed self explanatory to me and were easy to understand what they did except the FFT button. On the right side of the screen from the top is reset view, zoom in, ruler measurement, cursor measurement, zoom in only on the x-axis, FFT fast Fourier transformation, save as text, save as JPEG, color mod, and finally show hide grid. Across the bottom of the screen are the automatically calculated values calculated values. I took this opportunity to calibrate the probe and made the square wave look as best I could. I connected the probe to the calibration terminal, clicked start device and I started getting readings on the screen.

No additional driver was needed and already built into Windows. Installing the software was painless and because I was on Windows 10. SainSmart DS802 Software Click to Enlarge Click to Enlarge After a little bit of googling the chips on board (Cypress CY7C68013A + Altera MAX-II CPLD) the DS802 looks like it is a prime candidate for hacking to add features and allow open source software. The main oscilloscope park and USB DAQ interface. So you can see this is a two-part device.

Automatic measurement: Maximum, minimum, peak-to-peak, frequency, average, RMS, rise time, positive pulse width, negative pulse width, duty cycle.

Trigger mode: Auto, regular, single trigger.

Trigger condition: Hardware trigger Trigger level + rising edge / falling edge trigger.

Voltage range: В±5v, expandable to В±50v with x10 probe, to В±500v with x100 probe (provided yourself).

Maximum sampling rate: 80 MSps per channel.

Output: 1k HZ amplitude 1.5V, 50% duty cycle square wave signal.

This is written from a perspective of a complete noob.

But we never really went into much depth and only looked at the signals generated by a signal generator. I used an oscilloscope in high school in a class called principles of technology. How the heck do I review an oscilloscope. A couple weeks later it arrives and my anxiety kicks in. I can get my nerd on and troubleshoot all kinds of things. When SainSmart asked to review the DS802, I was pretty excited. I have always wanted to have an oscilloscope and add it to my tools. Today weвЂ™re going to look at the SainSmart DS802 Dual-channel oscilloscope.
