HP4145B data output to PC

[Bryan B]

I am using the Labview Data Output VI to load test data from the HP4145B onto a PC. This works for loading whatever variable is on the y-axis, but whenever I try to load the x-axis data I get a blank string (ie for an IV curve I can only load the current levels, and not the associated voltage points). I have also been unable to load the results of any functions. Has anyone else encountered this? What can I do? Thanks!

Hi Bryan,

Have you downloaded the driver for this instrument? You can find it at the following site:
http://sine.ni.com/apps/we/niid_web_display.drv_results?p_app_area=&p_man=&p_keywords=HP4145B&p_inst_type=&p_env=&p_drv_type=&p_int=

The driver will have specific examples for this instrument in LabVIEW and it is a lot easier to program with. Check this out and see if it helps.

Thank you Jen. I was already using the 4145B instrument drivers you mentioned, specifically the Data Output VI (Labview version 7.1). I still cannot find a way to load the data for any pre-defined sweep variables or function results--does anyone know if this is possible? I have had success loading measured variables, so I think this is an issue of what variables the 4145B makes available for transfer. Thanks!

Hi Bryan,

I found this post and it look similar to what you were describing.

There looks like there might be a possible workaround that Casey posted at the end of this forum.
