The unit for testing a plurality of tracks of a high-speed recorder in parallel comprises an emission subassembly for the transmission of data to the recorder to be tested and a test subassembly. The emission subassembly mainly comprises a generator for producing a pseudo-random or ramp-function sequence of binary numbers consisting of a plurality of binary elements in parallel. The test subassembly comprises a data storage device for storing the data reproduced by the tested recorder, a second generator programmed in the same manner as the first, a device for comparing the reproduced sequence with the emitted sequence and an error analysis device which delivers a measurement of the error rate and serves to locate the detected errors. |
