Automated test equipment is as follows.

Before conducting inspections circuits multichannel communication systems operator on the PC 1 selects a program corresponding to a specific mode of the test. After running the program, check the PC 1 through the switch 2 channels transmitting unit 3 control circuits for the unit 4 control command set for checking circuits. Unit 4 control sorts the received command, and sends them to the virtual reference 6 and the imaging unit 8 output signals.

Virtual reference 6 on the basis of the received command generates and transmits a multi-line block 5 comparison signals, the magnitude of the voltage corresponding to the signals of the controlled circuits in digital form during their normal operation.

Driver 8 generates output signals on their outputs and passes on the chain of the controlled object pulse and analog signals, the magnitude of the voltage corresponding to the pulse and analog signals interacting with the circuits of the controlled object. The same signals from the imaging unit 8 transmits output signals to the multiplexer 9 and then through the switch 7 to the inputs of the block 10 normalization in accordance with the commands of the control unit 4. Unit 10 the normalization converts the received pulse and analog signals to digital and sends them to a multi-line block 5 compare, where they are compared with the signals that should be generated at the outputs of the driver 8 output signals in accordance with a given program verification. The results of the comparison are passed on the command BC is ka 4 control through the switch 2 channels on the PC 1. Thus, the PC 1 performs the operation control of the imaging unit 8 output signals. In case of unacceptable deviations of the signals generated by the imaging unit 8 output signals from signals that should be generated, the PC 1 transmits to the control unit 4 a command to terminate the operation of the imaging unit 8 output signals.

Then, the multiplexer 9 receives at its inputs the signals from the controlled circuits and transmits them via the switch 7 to the inputs of the block 10 normalization in accordance with the commands of the control unit 4.

Unit 10 the normalization converts the received pulse and analog signals to digital and sends them to a multi-line block 5 compare, where they are compared with the signals from the virtual reference 6 in real time. Unit 10 the normalization includes meter 11 voltage, determining and converting into digital form the voltage coming from the circuits of the controlled object, and the measuring circuit 12, the incoming signals defining features or no break in one way or another circuit, and converts this information into a digital code. The results of the processing of signals from unit 10 normalization method comparison with signals received from the virtual reference 6, are transmitted multi-channel unit 5 compare to the PC 1 using the unit the 4 control through the switch channel 2. On the basis of the results of the signal processing personal computer 1 decides on the validity of the controlled circuits.
