GSS6450 blue binary code data
"We have several GSS6450 units, used for multiple purposes, and are happy with them. The bandwidth and quantisation bits give a very good representation of the RF environment. Other positives for us are the user-friendly GUI, portability, and ease of integration into an automated test framework (via TCP/IP)."
