NANL-B500G-RE capture aborts

Q

During a running capture the progress aborts sporadically or permanently with an error 0xC066000B "No free DMA channel available. Probably host is too slow".

A

Check if the laptop’s controller has hardware support for TCP checksum offloading and TCP fragmentation/reassembly. This would dramatically reduce the CPU load for the TCP/IP stream communicating with the netANALYZER.
