This looks like a laboratory for learning or testing airplane communications equipment. The second photo shows an FuG III configuration in the back, but the other devices belong to a direction finding system which I have not seen yet.
The closest thing that this could be is some version of the X-Gerät. This was a device which allowed night bombers to be guided to their bombing targets by receiving transmissions of dashes to the left of the target, and dots to the right. When the airplane was dead-on target, the dashes and the dots combined together to produce a constant tone. This is what kept the plane on target throughout the night.
