Multiple channels from Signal Express

[JPP]

I have 3 channels from a NI9219 from which I read a Voltage, Thermocouple and RTD at 1000 samples/s for 1000 samples then calculate the DC level for them, display and log.

Unfortunately when I export to Excel, each channel appears in a separate worksheet, even if they were on one dataview during playback. How do I set the recording so that each channel appears in a separate column in one worksheet ?

Hi JPP,

What you should do is to log the data to an ASCII file as you currently are, then open the file in Excel. It will open as one worksheet.

It is expected behavior for channel data to appear in a separate worksheet when exporting data directly from SignalExpress to Excel. It can be seen that the “Export to Microsoft Excel” option appears the same whether done from the DAQmx Acquire step or the Save to ASCII/LVM step, and is independent of the file options in the Save to ASCII/LVM step (such as one X column for time, or one for each data channel).

If you would like to see different behavior, I would encourage you to visit ni.com/contact and submit a product suggestion in the lower left. Thank you.
