Keithley 6517b Sweep measurement

[alachu]

Hello everyone. I want to use Keithley6517b to perfrom a sweep.

Instruments and method: Keithely 6517 b, NIGPIB-USB-HS, Labview 7.0, Windows xp, using 2400 SWV linear stair with DCV. gpib.vi.

Unfortunately, 6517b always shows error messages when click setup DCV:

Error code=-113 Undefined header;

Error code=-102 Syntax error.

What should I do?

If I use test_seq.vi from NI website, other errors were also found in front planel:

Error out 6 GPIB reading in ….

What is the problem?

Thanks a lot

Dear alachu,

According to its VI description of 2400 swV Linear Stair with DCV - gpib.vi (as follows),
the VI seems to be for other Keithley devices.

-----------------------------------------------------------------------------
Keithley 24xx SourceMeters
This Vi performs Sweep Voltage, Measure Current operation. 
The Vi can also use the 24xx as a DCV source.
-----------------------------------------------------------------------------

You can download a LabVIEW 7 example for 6517A/B at:

Hope this example will work fine.

Best regards,

Dear Mr. Yusuke,

Thanks you very much for your kind reply and help.

I found the example you provided works well in 6517b, but the voltage was fixed,

which means no sweep.

Would you kindly give me some advice?

With best regards,

alachu

The voltage is anything but fixed. Look at the code in the 'Vsource ON-OFF' event and you will see how to control the voltage. Put that inside a while loop with a shift register where you increment the voltage each iteration and you have your own sweep program.

Thanks for your useful suggest. However, my research is chemistry and I know nothing about Labview.

Could you kindly tell me the details?

Thanks again 

[alachu]

I mean could you give me a sweep vi available.

Deep thanks.

Have you tried doing a search for 'sweep'. An example was posted last week. You can also use the Ramp function that is in LabVIEW.

Before attempting any more programming, take the free tutorials.
