Agilent 4156 bug or Labview driver bug?

[Evander]

Mannually it does work. The problem also happens when I set SMU1 to COMMON.

I read the error codes for 4156 and it seems, you not configuring your Measurement Page properly. Do not leave any SMU/PGU/VSU/VMU un-configured. You get the error since PGU is not  configured properly.

Code 1 is for measurement error

Code 07 is for PGU

Code 4 is for Syntax error

Thats why you get 10740000 error.

Hope this helps. Let me know if you need more clarification.

Hello,

I think I found the problem, is about the series resistance for each channel. The driver sets the series resistance for each SMU and there can be set only two series resistance, so for SMU1 and 2 it is working but for 3 it doesn't have any resistance to set. So there is the error comming from. Now you have 2 possibilities, one is to modify the driver so that for smu3 and 4 it doesn't write to the gpib port, or you can send yourself commands manually.

Thanks a lot! I've been ignoring this error and my program has been running OK.

Hi Evander,

I meet this same error when there are three channels connected. In fact, I only need SMU1 and SMU2. But when I just have defined SMU1&2, there is error said that VAR1 have been assigned different channels. When I add and define SMU3, there is another problem said that the invalid setup. Could you please tell me how to solve this problem? I am quite new about the LabVIEW. Thanks.
