Dear All
In my mueasurement file i have two columns. First column has the value of the variable and second column has the number of times that value occurs in measurement. e.g
Value-----# of times
2--------------3
4--------------1
3--------------2
Values in both clumns are not sorted and re arbitrary.
Based on this example i want to generate a 1 D array which has the value in Column 1 repeated number of times in the second column. The above example will then become a 1 d array as follows.
2
2
2
4
3
3
At average there are 5000 measurements in one file.
Can you please help.
Thanks

Dear Members
I am a novice to Labview. I am trying to run this file from Keithley to control my 2400SMU.
http://www.keithley.com/data?asset=10313
I ahve the relevant VXI PNP driver installed from
http://www.keithley.com/data?asset=7145
However when i run the file, i get the follwoing error.
Ke24xx Initialize.vi<ERR>Driver Status: (Hex 0xBFFF0015) Timeout expired before operation completed.
Can any one please help me out with this problem.

Dear Group members
My basic problem which i want to solve is................Source a Current ramp and monitor voltage in real time(not at the end of the ramp or cycle), i want to compare the measured voltage against two threshhold voltages(set as constants) and control the direction of ramp(up or down).
I have a new file (attached with this post) which i downloaded from Keithley website. I modified it to work with my 2400. It works fine and sources the ramp and measures the voltage.
PROBLEM is that i get the measured data at the end of the cycle(all 100 or whatever number of points i set) so i cant compare the measured value against my thresholds in real time.
How can i get the measured voltage after every increase/decrease in the source current ramp so that i can then compare the measured voltage and decide when to change the direction of current ramp.

I am trying to build a VI for use with the Keithley 2400 Source Meter. My Intention is to Use a Linear CURRENT SWEEP and measure the voltage at each incremental level. Based on the vlaue of read voltage i want to control the direction of ramp i.e up or down.
The attached VI does everything correctly in frame 1 but when in frame 2 READ? is executed(i think 2nd time and thereafter)i get an indication on the Instruemnt
Error Code -410 Query Interupted
The graph does not show any values measured.
Can you please help to resolve the issue.
