Domenic, Whenever you are transferring data from a transmitter to a receiver it is reasonable to use some sort of framing. If you want a quick test, use a packet encoder and decoder on your transmitter and receiver, respectively. This will packetize the data and eliminate the continuous flow of "garbage" data to your file since the decoder will only output data from valid packets(w/ header + crc are removed). Bit errors will manifest themselves as a "short file", since bad packets will be discarded. If you run the block in verbose mode there may also be reporting for when packets are discarded. Set the payload length number in the encoder so you have a known relationship between the number of bytes missing from the file and the number of packet errors. There are numerous ways to improve this simple test, but this is a start for you. Also, you may want to perform a more fundamental bit error test. See error rate block. -J On 12/09/2011 07:29 AM, Domenic Magazu III wrote:
