Hello,
I am trying to acquire an ECG, with a USB-6008 card.
I have used DAQ Assistant, in continuous acquisition mode, with 1 sample to read with a 500 rate. I want to see the signal has in a oscilloscope.
But, I have a problem, I cannot change the x-axis or the time division. For example, to see more or less ECG's int the chart.
How can I fix this?
Best Regards,
Carlos

Hi rezituh,
if you double click on the scales for the axis you should be able to type in a new value. If you want a specific scale, make sure to turn off Auto-scaling by right-clicking on the plot and going to X Scale >> AutoScale X (there should not be check mark next to it if it's off). you can also right-click on the plot and go to Properties. The properties window will pop up; go to the Scales tab. You can change the divisions there.
Post back if you have more questions.
