Channel Subclass

For channel allocation of analog, subclasses are defined for the schemes of reception and transmission.

Subclass helps filtering the channels on direction (RX or TX) and services (Acquisition or Aperiodic transmit).

Reception

Since all ADC channels support the same subclasses, so any of the following subclass can be used.

To get the receive channel handle, the following subclasses can be used:

Constant	Description
MXF_SCLASS_RX_CHANNEL	Generic receive channel
MXF_SCLASS_RXACQ_SRV	This subclass is used for the acquisition service.
MXF_SCLASS_RXSAMPLING_SRV	This subclass is used for the sampling service.

Transmission

Since all DAC channels support the same subclasses, so any of the following subclass can be used.

To get the transmit channel handle, the following subclasses can be used:

Constant	Description
MXF_SCLASS_TX_CHANNEL	Generic transmit channel
MXF_SCLASS_TXAPERIODIC_SRV	This subclass is used for the transmission service.
