Hi,
I hope to have posted this on the appropriate section. I have just signed as new member so bear with me if I do not know how this forum works.
I have just purchased a USB Oscilloscope DSO-2090 and am having a hard time making it work. I have not used an oscilloscope since university and never used a USB Osc. The user manual this unit came with it is unseless. Perhaps assumption is made buyer is familiar with how to use it? Here it is my problem.
The unit came with one cable that connects Osc. to computer but at the computer end has 2 usb one red and one black. I connected only black usb to the computer and the light is flashing (on Osc.). I tried to make measurements after installing software but it is not measuring correctly. Measuring DC signal and shows sine wave on the screen!!!! Voltage measurement is also off. Should I connect both USBs (black and red)to the computer? I was tempted to do this but did not want to take risks as it may ruin Osc.
Does anyone know where I can download a manual on how to connect this to computer and how to take measurements? Your help is appreciated.
