Hello,

I am using Labview for a week now, the first step of my labview project is to retrieve data from the B1500A analyzer to my PC.

Communication between the PC and the analyzer is made via GPIB-USB (Agilent 82357B) interface.

I know that the connection is being made, the enclosed test file works well (when nothing is running in the analyzer). Also, the analyzer appears in NI-MAX and Keysight IO connection expert. NiVisaTulip.dll is also checked. However I am unable to see data with my prototype-1-b1500a program, and I keep having the following error : code : -1073807339 : VISA Write in Agilent B1500.lvlib:Configure Measurement Mode.vi->prototype_1_B1500A.vi

I did notice that when I use EasyExpert software of the instrument, the GPIB communication stops and my test file can not write the *IDN? Command, the NI-MAX and Keysight IO connection expert do not detect the device anymore. The following error appears : code : -1073807339 : VISA Write in test.vi

Does someone know what the problem is ? Thank you for your reply.  

PS : my OS is Windows 7

Hello everyone,

I am know trying to communicate with the analyzer by only using the FlexGUI. The purpose of the program is to get capacitance value in the time domain. To do so I am using functions from the driver downloaded from the NI instrument driver finder.

The problem is that no matter what configuration I use to get the data from the CMU unit, the instrument return the following error : command not available for SMU. However I am able to get SMU data such as current.

Is there something extra to do in order to use this driver ?

Enclosed is the program that can get current values but not capacitance.

Thank you for your reply
