Merging PXIe-4162 channels

[kevmmartin]

Hi, 

I'm building an automated test system and I want to use the channels of PXIe-4162 in such a way that I can combine some of them to increase the possible current (A) that can be handled from the DUT pins. Based on one of the TSM VI templates (picture attached), it looks like two channels can be merged. It would be beneficial to know whether more than two channels can be combined, will this be possible? Or maybe due to some configuration restrictions of the module, this might not be possible.

Thank you.

You can merge multiple 4162 channels for increasing the current capability. Please refer NI's whitepaper on merging SMU channels.

The attached image in your post looks good as long as one of the merged channels is disconnected and you have handled the sessions array appropriately not to turn ON a different channel as the one intended.

Note: All current measurements and voltage measurements from merged channels needs to be handled on the software side (if all merged channels are active at the same time)
