HP 4155B Instrument Driver Causes Equipment Error

[hrlazar]

I am fairly new to LabView as a warning and I am using version 6i. I have an HP 4155B Semiconductor Parametric Analyzer working on GPIB and I found the instrument drivers that really helped me get started in programming a user interface for it. Unfortunately, there is problem with them. I run some of the vi's and they work fine but two of them give me error code -1300 such and such.vi:SMU being configured not installed or instrument not initialized. The two vi's are called HP415xA_Config-Sweep-Parameters and Config-Sweep-Constant. After reading a bit on the newsgroups and such, I found that maybe they are talking to the system and telling it is HP4155A instead of HP4155B resulting in the error. T
his is only a hypothesis though and I can not find this even with step debugging.

Has anyone experienced this or knows how to fix. Any help would be greatly appreciated.

Thanks

I haven't use the particular HP equipment that you are working with but I have worked with other HP/Agilent equipments that produces similar error.

Given that you are able to run the other VIs and not these 2 in particular, I would imagine that you have configured your device correctly.

Could you check the parameters that you are sending. Make sure that they are what the driver supports. Make sure that the units are correct. Use the HELP if available.

Can you verify that the Config_Sweep-Paramenters and Config-Sweep-Constant is supported by the equipment that you have?

The HP/Agilent drivers are sometimes too generic and thus there are sometimes commands that are available in the driver but not necessary usable.

Lastly, if all else fails, give HP/Agilent a cal
l and someone there would know about this.

Hope that helps.

I have seen the same error that you are describing. The error is created in
the VI's that you mention when the command you are trying to use does not
match the configuration determined during initialization. If you look at
the inputs to the Initialization VI, you will find the standard Reset, ID
Query and a third input for active error checking. Disabling the active
error checking should eliminate the error.
