Interfacing labview with keithley source meter

[Dennis_Knutson]

The reads and writes are the functions in the driver to set a voltage and to read a current - the things you are trying to do.

Connect a chart to the output of you read.

I don't have a Keithley and I don't have the drivers.  So I just put comments where you need to put your Keithley code.  You need to learn how to use the drivers to set up the Keithley, write to it, and read from it.  I cannot do this for you.  You must make an effort and then I can assist you after you have written some code.  Look at the examples that Keithley provides.  Search their website.  Look for some Labview examples.

hi

i am trying to make measurements using keithley 2400 interfaced via rs 232. I have been successful in outputting the values being measured into text files. but now i have a problem in incrementing the value of the input voltage/current what i want to do is to give a particular voltage to the device under test and make a measurement. then immediately change the polarity and make another measurement. after this 1st step i want to increment the value of the voltage and repeat the first step .

here i attached the code for the first step. but i am unable to do the step 2. i am new to labview. can anybody help me. i am using labview 8.5.

Hi Sam,

you need to use a loop structure to start over again... (See message 9 for reference!)

thx

Is there a way to get configuration information from Keithley 2602 instrument (such as current range, channel, source function etc)? The property node does not seem to have that information.

Thanks!

[Dennis_Knutson]

What property node are you talking about? The only drivers that have property nodes are IVI drivers. Is there one for this instrument?

p.s. I would have been better to start a new thread instead of hijacking an unrelated and older thread.

[Vladiator]

Keithley uses VISA resource (Instr class), so there is no IVI drivers for it.

[Dennis_Knutson]

That has nothing to do whether or not there are IVI drivers. The instrument itself does not care at all what sort of driver you have chosen to use. If you are using a LabVIEW driver instead of IVI, then of course there are no properties for the instrument. In order to find out how it is set, you must do a query with the appropriate SCPI command.

How do I do a query and what commands do I use to query these properties?
