Reference files, Setup files and the analog input 
channels can have individual file labels set.  
For the analog channels and reference waveforms, 
the file label can be displayed next to the 
channel/reference indicator.  
The file labels are also obviously used to identify 
reference files, setup files or channels when saving 
or recalling waveforms and setups. 
 
In the example above, the file label for channel 1 is 
displayed next to the channel indicator and is also 
displayed in the Save Waveform menu. The Ref_1 
file label is shown next to the reference indicator.
