PURPOSE:To attain the simulation suitable for various handshake systems by connecting a receiver to a handshake simulation device for transmission to perform the test for reception function of the receiver. CONSTITUTION:A signal representing the state for data transmission from the receiver is inputted to a polarity selection circuit 4 via line 3 of a handshake simulation circuit 2, a switch 9 is conductive, the state is brought into positive logic, which is led to a line 10. Then it is fed to a control circuit 11, where the response time and pulse width are set to a desired value depending on the combination of dip switches 19 and a clock pulse from a clock pulse generating circuit 15. Thus, the simulation leading the signal representing the state for transmission to the receiver is attained in response to a signal representing the state for data reception from the receiver. |
