Need urgent help with communicating with the HP 4155B analyser with Labview

[u1rm2]

i folks,

I'm currently trying to communicate with our HP 4155B semiconductor pamaremter analyser.  I do not have experience with GPIB yet. I have installed the NI VISA.

I was wondering if anyone could help with getting me started on how to start communicating with the device using Labview.

I'm not certain where to start.

Kind regards

Rob

Hi,

In LabVIEW go to Tools>Instrumentation>Search for Instrument Drivers. With "4155" you should find and be able to download and install an driver for the device.

You will find the VIs including examples within the Instrument I/O palette in LabVIEW then.

Hi,

Thanks for the help. I now have communication with the instrument.

I was wondering if it's possible to to setup a data measurement (I-V Sweep) and be able to read the measurement data in realtime as it is being measured. So I basically see the graph updating itself on the PC during the measurement.

Is this possible? Could anyone give advice on how I can go about this or are there any examples that can help me understand how to do this?

I'm not completely sure how to initialise the instruemnt for communication and handle VISA WRITEs and READs. within LabView

Best regards

Can anyone advise with regard to reading the measured data in real-time and transfering it to a graph in Labview?

The only way to do this would be if the instrument supports setting a single point and then doing a single point measurement. You would create a ramp array and pass this through a for loop with the single point write/read. I have not used this instrument so you will have to dtermine this yourself from the information in the manual or by asking Agilent.
