Ground connection of NI 6541

[dpacaba]

Hello:

Could anybody describe the ground isolation of NI 6541 HSDIO.
I know it is single ended, but what about the connection between the GND terminal and chassis ground?
Are they shorted or is there a specific impedance in between them?

Thanks in advance.

Hello,

The board ground and chassis ground are connected.  There is not a specific impedance between the two ... it will act like a short.
