Communicating Stanford DS360 UltraLow Distortion Function Generator with LabVIEW

[PIPL]

I dont know where should this message to be posted.

I want to communicate with stanford DS 360 function generator, from which i want to acquire a B-H Loop.

From the aqcuired B-H Loop i want to calculate some parameters like Y-intercept, Y-max , Y-max & Y-min for a X-value.

To do this what should I've to do ?

Does I require any NI Card ( if yes, which one ).

Thanks for helping

The instrument probably has a GPIB interface. You should be able to confrim that by looking at the manual for the instrument. Assuming that it does and not a serial port for remote control, you will need to have a GPIB controller. There are a variety of controllers that you can use. The main page for NI controllers is http://www.ni.com/gpib/.

Once you have the hardware and software for it installed (NI-488 and NI-VISA), you should download the driver from http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9380659CE034080020E748... and try to use that to communicate to the instrument. You've also got the Instrument I/O Assistant for simple tasks if you don't want to use the driver. You might also want to look at the information on instrument control fundamentals at http://zone.ni.com/devzone/cda/tut/p/id/4359.

Ya it do have a GPIB interface and I've downloaded its instrument driver also.

In the library file which is provided as instrument driver, how can i aqcuire the B-H loop??

Since i dont have the function generator (Stanfoed Reasearch DS360 ), its in the customer place only

How is the B-H Loop obtained through this instrument driver provided.

You will also need some sort of instrument for measurement. The function generator is just a source. A quick google search of 'B-H Loop' found this. It includes a program. With the driver, you can set the AC voltage and frequency. If you have an NI DAQ board, you can then use the program as is.
