Agilent/Keysight 4155A parameter analyzer continuous sampling mode

[lodhi33]

Hi everyone! 

I am working on a project that extracts data from the Agilent/Keysight 4155A (semiconductor parameter analyzer). Earlier, I was running a data extraction after I got data on my instrument from a single sweep. 

I wanted to create another project now where I am running continuous sampling on the analyzer for voltage. And I wanted to plot the voltage I get from the analyzer on a labview graph or excel sheet in real-time. 

I am fine with delay in the data logging on my PC, but I wanted the number of samples/s being logged equal to that that the analyzer is giving me. I am okay doing a sample rate less than 50 measurements/s.  

Till now, I have been using these download trace functions to get data from the agilent analyzer, I do not know of any data VI that allows simultaneous data plotting.... What agilent driver function should I use if I want real-time data plotting? 

I also had a second question about the Agilent 415X drivers. Are these compatible with LabView 2019 version? My agilent driver VIs show just alright on labview 2020 but do not work with 2019 version of labview. Is that an issue faced before? 

Thank you. Any help or guidance is appreciated!

Hi

When drivers are recompiled in a higher version, the lower version cannot read them anymore, but instead of saving them for previous (what is possible) you can download a lower version from the NI pages.

I see!
Thank you Albert. Which of these agilent drivers should be workable with LabView 2019?

I have checked link provided. Usually driver should be masscompiled for each version of LabVIEW under ADE and uploaded here. But for Agilent 415X series all links are downloading driver masscompiled for 8.2.1.

So you can download driver from any of the link and masscompile(Tools>>Advanced>>Masscompile) on your LabVIEW version and start using it. As mentioned by Albert.Geven once you masscompiled or saved a VI in higher version, it won't open in lower version.
