When you do not want to spend a high price to buy a traditional oscilloscope, a signal generator and a logic analyzer. The highlighting advantages are the optional modular structure and high performance price ratio. It can be extended to achieve oscilloscope, signal generator and logic analyzer triple main functions by inserting different sub-modules.
Comes only with what’s in the photos, PDF manuals still available online.
the software works fine with widows 10 and the driver installed automatically. sainsmart dds120 pro 20mhz pc based usb digital storage portable oscilloscope. Cosmetically in excellent condition, no packaging, It looks as though has not been used at all, it came from a storage unit auction that also had a lot of new electronic items. sainsmart dds line, offerfunctionality for small.
5.8V in 2V/div and 5.6V in 1V/div thumb ruled instead of 4.93V.USB PC Oscilloscope Sainsmart DDS-140 with Logic Analyzer Module.
Depending on the selected V/div it was too high, i.e. With DC selected I didn't notice any "out Of Range" too. The advantages are the optional modular structure and high performance price ratio. Rising/falling seems fine, trigger level is a little mystery, only no trigger was working. Customer reviews: 14 ratings Product description SainSmart DDS140 is a medium-performance oscilloscope which can be extended to achieve oscilloscope, signal generator and logic analyzer triple main functions by inserting different sub-modules. With AC selected, Voltage is fine, 4.93 V differed between 4.89 and 4.97 V, triggerpoint is the middle vertical line. No more "Out of Range" with 5V, all signals were shown and sometimes they were triggered too. Loupe same crap, use with care, no side shifts 4. Slew rate / steep curves same bullshit, even 100 Hz rectangles show rounded edges. It displays 16 MHz same known shit but it displays.

ON Sainsmart's HP I found an older version of DDS140.exe (v 1.2) inm Analyzer/Generator sections offered as The Newest Version 1.USB PC Oscilloscope Sainsmart DDS-140 with Logic Analyzer Module.
I did a few quick checks only, all seemed ok. Should I return it? Or fuck the warrenty, open it and try for tuning up? Yesterday I soldered q&d an AVR-DDS, it's quality isn't the very best but not as shitty as on my poor screen With these curves I wouldn't complain On youtube I found a video where the 1kHz test signal looks like it should, so maybe my device is faulty Monday crap. Depending on signal and noise the value decreases mostly between 20% and 40%. Allows the user to scroll between bmp images on a SD card using SD Class and Custom event handlers to suit the non genuine chip on the Sainsonic Screen.
Here's an example I wrote with modified demo code of how to deal with the Touchscreen chip on the Sainsmart. Changing to 200mV/div should halve the value. I've been using a sainsmart, Has a dodgy chip that doesn't work with the Utouch class. Depending on signal form and noise the value raises about 10-30%. result > 6.5V -> blank screen, loud beeps and permanently flashing warning "Out of range!" 2nd, relative value, by 10 divided signal in 100mV/div area Changing the screen divider to 50mV/div should double the value. Two examples: 1st, absolute value, USB Voltage / AVR supply, roundabout 5V (4.8V - 5.13V may occur) 5Volts are "transformed" to 6.4V - 6-5V., three possible scenarios: - resulting voltage curve will be displayed - 6.4V Curve is displayed and a wrning message is blinking, sometimes paired with beeps. As long as I'm able to work bugs and glitches are a only a minor problem. within the loupe func you should be able to scroll left and right.unfortunately the arrows are greyed out always.

At least there are two probs, HW and SW! For ex. SainSmart DDS Series User Manual (Software) For Oscilloscope.
