Re: Interfacing HP3458A DMM using LinuxGPIB.

["Wang, SuYin Grass via Tech-talk" <tech-talk at aps.anl.gov>]

Hi Kuldeep,

I am using HP3458a recently with BASE:7.0.4 and ASYN:4.40.

This module support is using devGPIB. If you only need the base function, this module is fine. 

If you need to add a new function, it could be devGPIB or StreamDevice. 

Using devGPIB would need to modify the module and recompile. The learning curve is steeper. 

StreamDevice is easier to learn. 

Best,

Grass

Subject: Interfacing HP3458A DMM using LinuxGPIB.

 

Hello,

I have to interface HP3458A DMM using Agilent 82357A over LinuxGPIB driver on EPICS 7.

I am able to communicate with the device using the stream module.

I now see a module supporting HP3458A is available. Does this module use the latest ASYN interface libraries? -> http://www.aps.anl.gov/epics/download/modules/hp3458a_cvs.tar.gz

The last modification to this library seems to be in 2004. subsequently I understand there were major changes in how the ASYN interface uses the GPIB bus

Reason I am asking this question is because this HP3458A module has lots of functions and commands incorporated. Which I will have to redo if I use the bare stream interface.

Please suggest me ways to incorporate support for HP3458A in the latest version

Thank you in advance.

Regards,

Kuldeep
