LabVIEW program for HP 4194A Impedance/Gain-Phase analyzer

[Baturin]

Ooops, read the register does just this function.... sorry.

The only strange thing is that there is no possibility to read X values through this VI. Although it can be easily modified to include X? command as well. It seems to be undocumented feature, not written in manual...

FYI...in the event you need to perform the same measurements as the HP 4194A but are no longer able to purchase these instruments since they've been discontinued, here is a link to an application note that highlights how to perform the same measurements using LabVIEW and PXI.

I'm glad to have found this Forum, it is just what I need at the moment.  I have NI 8.1 developer suite and a 4194A Z analyzer.  I have downloaded the sample.VI discussed earlier and presume I also need the NI driver for a 4194A and Comm interface for HPIB as well.  any recomendations?

Can anyone save me some time with implementing this same capability? I have the 4194A analyzer with GPIB comm, NI LV version 8.1.  I downloaded the 4194A plug and play driver, sample programs and now need the COMM interface to GPIB.  will the GPIB-USB-HS interface work well?  any other recommendations?

Manoj, I have the same problem did you get this to work yet? Im trying to do the same thing

There is no such thing as LabVIEW 8.1 and I don't understand your reference to Comm interface to GPIB.

You need NI-488.2 and NI-VISA hardware drivers that you can download from the support link. Be sure that the versions you download are compatible with whatever version of LabVIEW that you actually have.

I have NI Prof Dev Suite 8.5.1, MY PC has a USB port, The 4194A has a GPIB port, I figured the NI  GPIB-USB-HS interface will work well.

[Dennis_Knutson]

Unless the instrument has a usb port, you don't have much choice.

Thanks, I'm a NI labview SW and interface novice but I would like to change that so please be patient.  I have multiple instruments old and new for ex Agilent, FLIR, MIniCircuits sensors etc.  At some point I want have to decelop a VI which controls and communicates with multiple devices.  For now I would like to start with just one old 4194A Z analyzer for experience.  The 4194A only has a GPIB comm port.  My windows 7 PC only has serial USB. I have downloaded from the forum an example vi for the 4194A and also the 4194A driver as well.  I have NI prof dev version 8.5.1 and I understand now that I will also need the interface cable GPIB-USB-HZ, NI-VISA, and NI 488.2 is that correct?

 is there a particular version of NI-VISA or NI488.2 that you recommend for a windows 7?

Yep, that sounds correct.  Just use whatever is the latest version.  If you order the GPIB-USB unit from NI, it'll come with the drivers you will need.
