Specify how the channel skew is determined
Description
For simultaneous sample and hold (SS/H) hardware, ChannelSkewMode is None. For scanning hardware, ChannelSkewMode can be Minimum, Equisample, or Manual (National Instruments only). SS/H hardware includes Agilent Technologies devices and sound cards, while scanning hardware includes most National Instruments and ComputerBoards devices. Note that some supported boards from these vendors are SS/H. Examples include the 6110E board and the DAS4020/12 board, respectively.
If ChannelSkewMode is Minimum, then the minimum channel skew supported by the hardware is used. If ChannelSkewMode is Equisample, the channel skew is given by [(sampling rate)(number of channels)]-1. If ChannelSkewMode is Manual, then you must specify the channel skew with the ChannelSkew property.
