The current configuration of apparatus in our main laboratory will be presented,
including pictures and some technical documentation.

Instrumentation is largely composed of test & measurement instruments, a customized dual analog computer, a customized audio signal router, VLF/HF/VHF radio communication receivers, and some additional equipment. All instruments are mounted into 12 standard 19-inch racks. Audio recording consists of 2-track and 8-track analog magnetic tape recorders. Graphic imaging is done by means of oscilloscopes, meters, numerical displays, and graphic XY and Yt recorders. Signal routing is accomplished by means of BNC-cable patching, except for the patch panel of the analog computer.

The pictures (by J. LeRovan) that follow will give some impression of this workspace.
Technical information (unclassified) is updated on regular basis.
