setting black level on 1405

[NeuroSteve]

Hi -

I am trying to increase my signal resolution by adjusting the black level and white level for acquiring an analog video image on a PCI-1405 board.  I can set the white level but any black level other than 0 gives an error.  It was my understanding from NI's marketing material that the 1405 card had programmable gain and offset, so shouldn't one be able to adjust both parameters?

Any advice would be appreciated.

Best,

Steve

Hey Steve,

You cannot change the black level, it's a hardware limit of the 1405.
