Hello,
With the addition of the SH96-96 cable, you are increasing the length of wire over which the unconditioned signal is subjected to noise. If you can accept this loss of accuracy, then you should not have a problem reading signals in this configuration.
The maximum cable length between the PC and the SCXI Chassis is 10m. Anything under that should work correctly.
Please let me know if you have any further questions.
Regards,
Sean C.
