SCPI Message App For Agilent VNA

[TonyJ]

Group,

Last year I got a new Agilent 5071C VNA.  This analyzer is an incredible instrument.  Unfortunately the NI driver only communicates with the VNA's main features.  Many lesser features that enhance testing are left out of the driver.  My only alternative is to programmatically use the analyzers complete features are to use SCPI commands.  I have a Labview .vi that works great and achieves all that is needed.  I assign a SCPI message into a string variable and all is done without having to work in Labview.  Unfortunately I'm no Labview guy and feel exposed should a problem arise.

I would like to convert this .vi or replace it with something that can be supported in LabWindows/CVI. 

SCPI messages allow me to almost completely removed all DLL's in my project.  My question, is there an already developed DLL that will allow me to pass strings (SCPI Commands) which was written in CVI?  A DLL that I can use with TestStand 3.5 or later.  If so, point me to the link.

Hi,

    I am very interested in your question, but i am poor in this question.

    Let's hope it will be answered ASAP.

Hello TonyJ,

Thank you for bringing this issue to the forums. I found a link on ni.com and I think it is what you are looking for. It is a LabWindows/CVI driver for the E5071C.

Let me know if this helps.

Thank you,

I'm familiar with these drivers and they are as I mentioned on the initial message do not completely take advantage of all of the ENA's capabilities.  I have other IEEE instruments as well.  I would like an application written in CVI that passes SCPI commands to my instruments.  Ideally within Specify Module I'd like to put in the SCPI message, IEEE address and whether its a Query/Write/Read and if there was an error.  What in CVI can allow me to send these ScPI messages in text form?
