Zusammenfassung:	The device includes following units: main control unit, a test clock unit, a display unit, a service bus interface unit, and a control bus intrface unit. The device also includes a service bus test unit (SBTU), and a control bus test unit (CBTU). Through service bus, SBTU is interconnected to the crossed single board (CSB); through control bus, CBTU is interconnected to the crossed single board. SBTU is in use for testing the service bus; CBTU is in use for testing the control bus. The disclosed device can test whether CSB is normal expediently and rapidly. Advantages are: simple constructionof system, low cost of device, easy of operation, locating fault precisely, and easy of maintenance. The invention is suitable to carry out production test for volume-produced CSB.
