ChannelSkewMode (Data Acquisition Toolbox)

ChannelSkewMode specifies how the channel skew is determined. The channel skew is defined as the time between consecutive scanned hardware channels. If ChannelSkewMode is set to Minimum, then the minimum channel skew supported by the hardware is used. If ChannelSkewMode is set to Equisample, the channel skew is given by (sampling rate × number of channels)^-1. If ChannelSkewMode is set to Manual, then the channel skew is set by the ChannelSkew property.

Since ChannelSkew is settable only for scanning hardware and not for simultaneous sample and hold (SSH) hardware, ChannelSkewMode can only be set to None for SSH hardware. In this case, ChannelSkew is 0. SSH hardware includes Hewlett-Packard devices and sound cards.

Values


`None`	This is the only supported value for SSH hardware.
`Minimum`	The channel skew is set to the minimum supported value. This is the default for scanning hardware.
`Equisample`	The channel skew is set to (sampling rate × number of channels)^-1.
`Manual`	The channel skew is set to the value specified by `ChannelSkew`.

The default value is determined from the hardware driver.
