Short Name: Most Space Available In Endpoint

Property of niFgen

Returns the largest number of samples per channel available in the endpoint since this property was last read. This property can be used to determine how much endpoint space to use as a buffer against PCI Express bus traffic latencies by reading the property and keeping track of the largest value returned. This property is endpoint-based.

If you want to minimize the latency for data to move through the endpoint and be generated by the signal generator, use the Data Transfer Permission Initial Credits property to grant fewer initial credits than the default of the entire endpoint size.
