agilent SCPI commands

[huskerli]

Hi guys,

I am working on SCPI commands to control my instrument which is Agilent B2901A in this case.

Now, I am able to control most of parameters via SCPI commands. But I can not switch the PULSE model from "OFF" to "ON". I also wanna switch the TRIGGER model from "MANUAL" to "AUTO". I DO read the manual and did some search online but still can not find it

I know is not LV question directly, but since no one answer me at Agilent Forum, here is my last hope.

Could anyone tell me what commands I need it?

Many thanks

Search the SCPI manual for "Pulse". How about: ":FUNC PULS" ?

"Partially supported":

:TRIGger[:SEQuence[1]]:SOURce

<IMMediate|TLINk|TIMer|MANual|BUS|NSTest|PSTest|BSTest>

Maybe you'll have to write a "SCPI wrapper" that will translate all unsupported SCPI commands to their Agilent equivalents.  That way you will have a "SCPI-compatible" driver.  🙂

It is still not working, but thanks for reply anaway.

I am not quite understand what's you mean. Is that need some sort of invoke node?

BTW, do I have a to install exactly driver? I am continuous work with a project someone left, looks like he installed Agilent 34401 instead B2901A, but so far is works. I am just not sure is that could be a reason?

Thanks

Hi there:

There are a few things that should be addressed.  First of all, noting that the installed driver was a different model than the instrument being used wasa BIG omission of info regarding your problem.  Even though ot has nothing explicitly to do with the code you presented, it DOES mean that perhaps this code was written with the wrong instrument in mind...

I strongly suggest reading the programmer's guide for this instrument before proceding any further.  It will probably tell you exactly what you need to know.

well do

thanks

I just installed the exactly driver but still not work.

I read manual one more time and found out Agilent supports two sets command sets. And the PULSE command is not in the default command sets. I believe that is why I can not do it,

but what else I can do to make it work?

Let's make something absolutely clear: the driver has nothing to do with the code you showed.  Don't get hung up on the driver issue because you are actually writing your own drivers right now.  The code that you've shown us takes the place of the driver.

That being said, Agilent indeed has a second command set unique to the instrument itself.  I believe these to be desinged to work interchangeably with the standard SCPI commands, and the Agilent commands will do the job where the standard SCPI command set has no equivalent.

Good luck!  🙂
