IO Trace: What is VISA Attribute 0xBFFF0002?

[Mr._Jim]

Hi all,

The Question:

Can someone tell me what VISA attribute 0xBFFF0002 correlates to so that I can track the bug?

The Context:

This week I've been asked to help troubleshoot some odious bugs that others are encountering.

In continuing that theme, I've got a VISA IO trace that someone has handed me, and there are several lines with an invalid session/reference error.

That error occurs when "VISA Get Attribute (0xBFFF0002)" occurs. I really need to know what attribute it's trying to fetch and a hex code doesn't tell me anything by itself.

 I saw that a couple of other such requests in the past went unanswered - I'd greatly appreciate any input.

Thanks,

Mr. Jim

from visa.h file:

#define VI_ATTR_RSRC_CLASS (0xBFFF0001UL)
#define VI_ATTR_RSRC_NAME (0xBFFF0002UL)
#define VI_ATTR_RSRC_IMPL_VERSION (0x3FFF0003UL)
#define VI_ATTR_RSRC_LOCK_STATE (0x3FFF0004UL)
