Disclosed is a test jig to sense moving of bus for micro channel structure. Circuit in the test jig comprises a micro channel slot(1), the first PAL decoder(2), an address latch(100), an address converter(200), the first and second displayers(300, 400). The first PAL decoder(2) decodes various signal from the micro channel slot(1). The address latch(100) latches a channel address from the micro channel slot(1) according to output from the first PAL decoder(2). The address converter(200) decodes binary output data from the address latch(100) into hexadecimal code. The first displayer(300) displays outputs from the address converter(200). The second displayer(400) displays current state fo bus cycle according to the ouput from the first PAL decoder(2). Thereby, the state of bus cycle is directly monitored, and the channel error can be captured.
