At this point, you may want to contact Keithley. Most Active Software Boards: The problem happened when I chose the sweep in terms of voltage rather than current. In my case, I need to plot a 3-D graph which has source-drain voltage X , gate voltage Y and conductance Z. Good luck in your applications!

Keithley Meter – IEEE (GPIB) Driver for LabVIEW – National Instruments
Unfortunaltely keithley engineers are strongly committed not to provide the block diagram. Does anyone has the block diagram for KIx. This is what I am thinking so far. This voltage sweep function works fine over a resistor, but nanovoltmeterr over a transistor. Message 9 of It is possible that there is some setting that needs to be made on these particular devices to voltage sweep a resistor versus a transistor.
Is this a VI that you had created? This may be the source of the warning; the sweep is starting and stopping keithoey 0 A. At this point, you may want to contact Keithley. Message 1 of You can contact an engineer at Keithley here.

Message 7 of But it seems trying to locate a resistance value for the device under testthat is unable to accomplished on a transistor. Message 4 of Message 8 of I tried running the program in “Demo mode” with your same settings, and the run was successful, without throwing a warning. It is an example software written by the Keithley.
Thanks for your reply. The problem happened when I chose the sweep in terms of voltage rather than current. For some reason, I was unable to open the data sheets and manuals on Keithley’s website.
I don’t know if you can setup such a “transistor”measurement!? I think that the plus with the conductance measurement software from Keithley are designed for resistor-like device: Message 2 of Message 3 of Kiethley should really invest in updating its drivers and examples.
Since this is an executable and I am unable to view the Block Diagram, I cannot troubleshoot the code. In my case, I need to plot a 3-D graph which has source-drain voltage Xgate voltage Y and conductance Z.
Most Active Software Boards: Since this is an executable that has been created by Keithley, there is no way that anyone other than Keithley can provide access to the code. Are you able to take a voltage sweep on a transistor?
I want to edit the program and make it convenient to me, as I suppose with my limited labview knowledge it will take more time if I strat from scratch. Message 6 of There is no manual of KI I am trying to use the “differential conductance mode” in software “KI As it says in the warning message, you may also want to check the connections of your transistor and verify that it is enough signal to be measured.
