friends, i am interfacing keithley 2612a with pc using labview. while attempting a program to measure current for sweep voltage source i am facing problems to store readings in buffer. my first case is to give staircase voltage sweep and then measure respective current and store both readings and source values in buffer/table. i got the result by using the program sequence given in attached file "2612a 1". But it is not satisfactory as it is very strange to develop such algorithm for other cases{e.g. logarithmic staircase sweeps,list sweeps and pulse mode sweeps}. there are commands given in manual which generate such sweeps directly {e.g. "SweepVLinMeasureI(smua,1e-3,10e-3,0.1,10)" to generate a linear staircase sweep of voltage from 1 mv to 10 mv and measure current at each step.} and also for buffer storage but whenever i make program using these i am unable to get readings in buffer. i have tried various combinations of several commands to get the result but failed. kindly download manuals(user and reference) from keithley website if required. i am also attaching my two programs that failed to store readings in buffer. "visa" is shown in "2612a 1" but i have used the same algorithm in "gpib" instead of "visa".
