A quick glance showed that there was a function for setting the bias voltage and the high level example called 590-CV Measurement uses it and triggers the instrument. The bias voltage VI is called V command and has a cluster as an input. Put this VI and the trigger in a loop and increment the value of the cluster with each iteration. <DIV></DIV> Wed, 08 Feb 2006 21:28:07 GMT Dennis_Knutson 2006-02-08T21:28:07Z https://ni.lithium.com/t5/LabVIEW/Interfacing-a-C-V-meter/m-p/321839#M166141 Hi ,<BR /> <BR /> i'm using labview to interface a Keithley 590 C-V meter.<BR /> I want to use the 1 shot trigger mode and make a loop so that for each<BR /> trigger it'll take one measurement and then again initialize another<BR /> trigger,<BR /> <BR /> can u suggest how i can loop the trigger and the bias voltage?<BR /> <BR /> Wed, 08 Feb 2006 05:10:39 GMT https://ni.lithium.com/t5/LabVIEW/Interfacing-a-C-V-meter/m-p/321839#M166141 Anonymous 2006-02-08T05:10:39Z https://ni.lithium.com/t5/LabVIEW/Interfacing-a-C-V-meter/m-p/322360#M166375 If you go to <A href="http://www.keithley.com/" target="_blank">http://www.keithley.com/</A> and do a search for 590, you will find a driver for that instrument.
