Inside The SDR 1000D (Photo #2)

Here is a second view of the SDR 1000D with the top cover removed. At this point I will reveiw the different PCB with in the 1000D, their location and also their function and operation of each PCB.

As the boards are horizontally mounted with the largest of the boards on the bottom . The bottom board is the interface PCB which provides the connections between all the other boards in the system and some of the "outside world" connections.

Some of the major connections to this PCB are; earth ground, X2 External Control Connector, Parallel Port Connector, as well as and external customer provided frequency standard input connector. These connections are visable on the Photo showing the rear panel of the SDR 1000D.

The interface card is a bit difficult to see because of it's location in the horizontal stack and at the very bottom!
