I have 4 signals whose data i am saving using 'Write to measurement file' in a .lvm format. Two of those signals come from DAQ and so I am able to label them within the DAQ setting of 'Channel name'. But the other two signals show untitled. How can I name these signals so that I can have their data saved along with the name of the signal?
when using LVM, you won't be able to set the specific names directly. I would suggest to use TDMS for saving your data. Here you can set everything that you need. For example you can set the names of the channels. Please have a look at the attached VI.
I'll further mention that in the loop, for each channel you want to set the name of, the attribute name for the name of the channel is "NI_ChannelName". The example in the thread above takes advantage of the fact that "NI_ChannelName" happens to be the first one defined. I think it would be more robust to not bother reading the existing attributes, and instead just write the "NI_ChannelName" attribute with whatever new value you want.
