The LJStreamUD is a software produced by Labjack that shows selected channels in a graph and then write it in a file. We used it to acquire data, so we could see the ECG waves in the computer.
You can choose the number of channels that you would like to display, so by default the Channels are 4 that corresponds to AIN0, AIN1, AIN2 and AIN3. Another option is “Graph”, so you can choose which graphs do you want to see. You can write all the data in a file, just clicking on “Write to file”. You also can change the scan rate frequency.
The images below show some ECG waves that we acquire with the LJStreamUD and the oscilloscope.
