U2722a Keysight source measurement unit

Thanks for your reply!

Just to clarify, were you able to move to higher limits, for example 1mA current limit, in LabView? Any value above 1e-6 gives me "data out of range" error even if I use the boundaries provided in the data sheet (1µA, 1mA, 10mA...).

Cheers

Given you guys are cornering LabVIEW that the SMU doesn't work only in LabVIEW, were you able to get it to work in other programming languages perhaps like C, C++, C#, Python or VBA? if so, could you please share the working code?

I feel that this has nothing to do with LabVIEW as a programming language and may be a bug in the LabVIEW drivers provided by Keysight, in that case, you can develop using just the SCPI commands using VISA Read/Write (this is an excellent tutorial - https://labviewwiki.org/wiki/VIWeek_2020/Proper_way_to_communicate_over_serial) by referring to the SMU's programmer's manual.

Hi Thank you for your comments. For me I don't have knowledge with other programming languages, with labview i do and with the drivers that are provided by Keysight it became easy to deal with. Anyway, this is the U2772a driver that I am using with steps I follow. I am using Labview 2019.

Dear naif64,

Thanks for sharing the VI. Now I understand your previous message about current limit/range.

You went around the current limit ivi bug by configuring the channel as current source during initialization, then switched it to voltage - smart!

I implemented your approach and and it seems I was able to resolve the problem as well.

Thank again for your help 

Cheers

Hi dk 2955

This has been done with the help of the supporting Labview staff.
