Where can I find more information on the HP4192A vi module?

[jeffery_langer]

I am trying to measure transadmittance using Labview and a HP4192A impedence analyzer. Unfortunately, the vi for the instrument does not let me have a static DC bias voltage, and an AC small signal and frequency sweep simultaneously. I tried to correct this by setting the start and stop bias voltage the same and having bias voltage step of zero. Can anyone give me information about another hp4192a control vi that provides greater control?

Thanks.

Jeffrey,

The ID Net Library's LabWindows/CVI instrument driver for the 4192a offers more control and functionality support that the contributed LabVIEW driver.

You have some options:
1. Use the CVI driver in a C-based environment

2. Convert the CVI driver using the conversion feature in LabVIEW. Using the menus, follow the path: "Tools >> Instrumentation >> Import CVI Instrument Driver..." Then, select the .FP file from the downloaded driver. You will then be able to use the features of the CVI driver within LabVIEW.

Finally, I found an application note (AN 346) on Agilent's website that may be helpful with the 4192A. I have attached that file below.

I hope that's helpful.

Here's a link to the procedure for converting a CVI driver for use in LabVIEW
