Theory of operation 

Models 707B and 708B theory of operations overview 

The Models 707B and 708B are composed of several components assembled into an aluminum 
frame. The Model 707B supports the operation of up to six relay matrix cards; the Model 708B 
supports the operation of a single relay matrix card. Each of the components is briefly described 
below.
