Each switch module is an individual 32×4 2 pole matrix. They may be interconnected to build larger configurations or used in series to make 3 stage matrices that maintain the bandpass of a single module to a great degree. For example eight of these modules may be cascaded through another module to make a 256×4 matrix with 10 MHz – 3dB bandwidth. Uses Two D37S ( Socket ) connectors and type A armature relays with the following specs:
