what are the instruments driver should be used to make measurement with agilent HP8753E

[ghabri]

Hello,
I'm doing a user interface with labview 8.5 to make measurement using a frequency analyzer agilent HP 8753E, so I must make successive measurements of cables, each time I made ​​the tests of the cable and then all the other now, my question is what are the drivers of istrument to use these to measure and how should I do and thank you very much

Hello,

While we do have many common third-party Instrument Drivers available for download at http://www.ni.com/downloads/idnet/ , it looks like we don't have one for this particular analyzer.  There are a couple options here.

One option is to request to our NI team to create one.  This is a process that generally take a few weeks at least.  For details on how this process works, see https://sine.ni.com/apps/utf8/niid_web_display.request_driver and keep me posted if you have any issues with that.

The other option is to use the NI-VISA drivers, which are the more general serial commands through LabVIEW.  The version you want for LV8.5, according to the Compatibility matrix, is available through our drivers database: NI-VISA 5.0.3. With NI-VISA, you will need to know the exact serial messages to read and write data from the analyzer, so be sure to refer to the documentation for that device.

Best,

hello,
thanks a lot Mr , i will try using ni visa , i have an example in HP Basic i have many difficult to convert it toi Labview can you help me to do that ?

Hi again,

Good to hear that you have VISA up and running.  VISA is extremely basic; you use VISA Open and VISA Close to open and close serial connections with the device, and VISA Read and VISA Write to read and write the actual serial messages with the device.  You will certainly want to check out the documentation for the frequency analyzer for the syntax on the serial commands.

You will want to check out the examples related to VISA in the NI Example Finder.  In LabVIEW, go to Help > Find Examples…, then in the example finder browse to Hardware Input and Output > VISA.  A good one here to start with is the GPIB-VISA.vi example, which goes through the basic format of Open-Write-Read-Close, as described above.

Hope this helps!  Best,
