Sweeping Agilent N3300A dc load using LV

[Dravi99]

Hello,

I am able to communicate with my Agilent N3300A, I wanted to sweep the load from 0 to 10A in steps of 500mA. I have the Aga33xa drivers for the same. I am able to set the load but not able to sweep it. I would like to know how do i do the same.

Any help is appreciated.

Thanks

Ravi

If the instrument does not have a sweep function, you can just step it through the loads you want in a loop. There are several ways to do it. Simplest is to just have an array constant wired to a for loop. You could also generate the array with the Ramp Pattern function. You could also use start, stop, increment controls. There is also a shipping example called Frequency Response that uses a for loop and a formula node.

Thanks dennis. i am actually working on that, this will surely help a lot to me. Was stuck at a point that, I was able to see the N3300A in my GPIB list in Max, able to communicate with that, but i have incidentally converted my Drivers to custom drivers for 3300A by I/O assistant. now i m stuck at getting the reading from the instrument.

It gets communicated. Now how do I set the load 3300A so that i can hook that to the board with LV? I was reading the tutorial for the VISA..your guidance will surely help.thanks again.

I'm confused by what you mean by the drivers were converted by the I/O Assistant. The driver available for download is an IVI driver and there is an example that ships with it. It shows the function for setting a current and doing a measurement. You would place the Config Current Level and the Read Measurement inside the loop.

Any chance I could get a copy of your code to operate the N3300A?  I am about to use the same load bank in a test.

Hi Tim,

I will have to look up. Its been some time that I worked on LabView after 2007. But will provide you whatever I have, I can find.

Thanks
