Abstract
A programmable channel emulator is disclosed which exercises a control unit to which it is attached to detect timing problems or error conditions in the control unit. A plurality of channel emulators can be concurrently operated in order to exercise the control unit in a multiple channel environment. The operation of the plurality of channel emulators is synchronized and controlled by a shared processor in order to emulate possible multiple channel situations that the channel control unit could encounter. Included in this system is a programmable delay circuit that operates under software control to provide a precisely controlled delay between receipt and transmission of signals between each emulator and a connected channel.
