QUOTE(Aitor Solar @ Apr 27 2007, 01:06 PM) Dear Aitor This realy did help and solved the problem. Once again thank you all.

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. Regards

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.

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. Regards Sajid SALEEM
