Keithley 2600 and labview

[emataev]

Hey all,

I am currently trying to set our Labview-Keithley interface. I have Keithley 2604B which is similar to the 2600 series.

I am dealing with FET devices and I will need to characterize them.

I would need to contniously supply voltage from both channels and measure the  current from one of the channels . Also I would need to sweep the channel potential  in  one of the channels while I measure the  the current from the both channels ((Typical I-V curve with a gate)).

Does anyone can share with me the .VI file that he/she created for this task?  Any help will be appricieated.

I know that the Keithley comes with internal TSP script but I need more than that therefore I would like to use LabView.

I have already set up a diffenet interface in between Keithley 2400 to labview, but the interface of 2600 is totally different (not the same communication).

Thank you for the help!

That is news to me. They both have GPIB.

If you mean that they have different command set, then I suggest you read the manual for the 2600 and translate your 2400 code over.

If you search the Instrument Drivers at http://www.ni.com/downloads/instrument-drivers/, you will be taken to Keithley's site where you can download a native LabVIEW or IVI driver.

Hey,

Thanks for the response.

In fact I have the labview driver but they just have simple examples. I would like to have the 2 channels working simulatniously and constantly plotting and saving the data.

For example:

I would like to record the current measurement from one of the channels for a long period of time (~ 1 hour), and at the maximum sampling rate that is possible. In this case I would have Isd versus time.

Another thing I would like to do is simple FET characteriztion, and for that I would need both of the channels simulatniously. While one channel is sweeping potential the other is stepping the potential.]

Any VI example will be appreciated.
