The 1553 Network Emulator worked exactly as advertised. It was delivered in a timely manner. It is a very cost effective solution for our company. It provides exactly the type of 1553 traffic we need to test our data acquisition systems. The Emulator is a very well thought out way of producing network traffic in a small and low priced unit. Other solutions to simulator 1553 network traffic are available, but we have not seen anything even close to being this clever nor cost effective. Our thanks and admiration to the creator of this unit.
