keithley 238, 2182 nanovoltmeter

[razipaleth]

hai,

i am razi, research scholar, pondicherry university. i have a keithley 238 source-measure unit and 2182 nano voltmeter. i want to keep 238 as a current souce and 2182 as a voltage measurement system for my samples. may i know how to make a labview program to connect both for the i-v measuremets for the same time.....

thanks for advance

Start by downloading the drivers for them.  From there, learn about State Machines.  That should help you get a good way there.  Give things a try.  Come to us when you get stuck.  Be sure to share your code when you do.

Neither are supported but they should get you started.

Thanks for the reply sir .

I have tried, and made a program for both. it works tooo.... The issue is that i have to mix both program together....which means i have to use 238 as a current source and 2182 for measuring voltage at the same time.

Thanks in advance....

So what is the exact problem? You've attached two separate VIs. You need a single VI with functions for both instruments. Have you taken any of the numerous free tutorials?

[crossrulz]

I'm surprised the drivers didn't break up those commands into subVIs.  Or did you just not use them?

I reiterate that you will want to look into the State Machine architecture.  Make a flow diagram of how you would do the process manually.  That flow diagram will help you immensely when you go to write your state machine.

That is exactly what i want. 

i want a single 'vi' which can be used for both instrument at the same time.....ie source meter will give the current at the same time the voltmeter will measure the voltage. i am sorry that, may  know what is "numerous free tutorials"....?

thanks and wish you a happy new year sir

Google 'LabVIEW tutorials'

Or if you purchased NI's SSP (Standard Service Package) for LabVIEW you should have access to free online training videos from NI.

Trust me here.  You want to break up your code into subVIs.  It makes things a lot easier to manage.  Your main VI can then call these other VIs to do the actual work.
