I am pulling, Voltage, Current, and Time data
from a keithley 2400. I want to set the time data as the time attribute
for the Voltage and Current data. The data is read from the insturment
buffer as a 1D array. I then use a decimate array to seperate the data
and a build array to combine the current and voltage data into a 2D
array. Then I output that array to convert to varient data and then to
set attribute. I use the time data array as the attribute value. When
converting back to labview data I loose that time attribute. I preform
a number of operations on the data using express VI's, ie FFT, and need
the proper time data not the default interger step. Also it would be
nice to adjust the names of the data so that they appear in the header.
Any help would be great thanks.
Ed PS sorry no net allowed in lab so I cant post the VI
You don't need a variant but a waveform! In a waveform you can store attributes like timestamps (make sure every point get's it's own timestamp or use dt and t0). If you set the 'NI_Name' property your data will have a name.
