Read data from Agilent 86100C Oscilloscope from GPIB interface

Hello everyone, 

trying to get my head around it. i am using Labview to control Agilent Oscilloscope 86100C to retrieve the signal and be able to plot the waveform in Labview. i have installed the device's drivers and used one of the existing example "Agilent 86100 Series Aquire Waveform.vi". when i run it i receiver an Error says : 

 

Error 1 occurred at Scan From String (arg 1) in Agilent 86100 Series.lvlib:Fetch Waveform (Normal).vi->Agilent 86100 Series.lvlib:Read Waveform (Single).vi->Agilent 86100 Series Acquire Waveform.vi

 

Not sure what exactly need me to do, but when i click on STOP in the Error window, it takes me where the Error has occurred Fetch Waveform (Normal).vi 

in this VI, the Error occurs in SCAN FROM STRING block as following. 

 

Error 1 occurred at Scan From String (arg 1) in Agilent 86100 Series.lvlib:Fetch Waveform (Normal).vi

 

i would be very much appreciate it, if someone could guide me on how to tackle this issue,

 

many thanks,

could it be that an empty string is returned?

so that scanning from that string generates an error?

Hi Jianxiaozi,

 

have you used the existing examples? do you have the same error I have or something different?

Yes, I used his example to find the same problem, and finally found that wait for acquisition complete.

And then I delete it, so VI goes through but it doesn't get the right waveform.

 

Do you have contact information or are you from China? I am afraid to solve the problem in the forum is not timely
