The proposed invention relates to the field of test equipment and can be used to test multi-channel communication systems.

Known selected as the closest analogue of the centralized control device containing a multi-line block of comparison and United with him the virtual pattern and the block normalization, the input of which is connected to the outputs of the controlled object (Pat. Of the Russian Federation No. 2141722, CL IPC H 04 3/46, publ. 20.11.99, bull. No. 32).

The disadvantage of this device is that it does not impact on the controlled object channels simulated using the virtual reference.

The technical objective of the proposed invention is to expand the functional capabilities of the device.

This object is achieved in that in the automated test equipment containing multi-block comparison, United with him the virtual pattern and the block normalization entered are connected to the inputs and outputs of the controlled circuits three shaper input and output signals, the switch connected with three formers input and output signals and block normalization, control and computing, coupled with multi-unit comparison, a virtual standard switch and three forms what routename input and output signals, moreover, the control and computing, multi-unit comparison, virtual reference, block normalization, switch and three shaper input and output signals are combined in the control unit of energy and information chains, it also introduced connected with the control unit and the calculation unit of the control circuits of the control unit and control; it contains no less than three sets of control circuits, which control units are connected to each other; however, the block normalization is made in the form of a voltage meter and meter circuit, whose inputs are connected to outputs of the switch, and outputs to the inputs multi-Comparer.

The proposed invention is explained using the flowchart shown in the drawing. In the drawing, the following notation:

unit 1 management and control,

unit 2 control energy and information chains,

- unit 3 control

- multi-channel unit 4 comparison

virtual reference 5,

switch 6,

- shaper 7 input signals,

driver 8 output signals,

the meter 9 voltage (ADC)

- measures 10 circuit (ADC).

Automated test equipment is as follows.

Before conducting inspections circuits multichannel systems spazieren on the unit 1 management and control selects the program, corresponding to the specified test mode. After running the checker unit 1 and control passes to the unit 2 control power and data circuits to the unit 3 control command set for checking circuits. The control unit 3 processes the received set of commands selects the commands to him, sorts them for shaper 8 output signals and the virtual reference 5, on their basis generates test signals and transmits the virtual Etalon 5 and the switch 6. Switch 6 transmits the received signals to the driver 8 output signals. In addition, the control unit 3 transmits to the driver 8 output command signals for opening or closing (on or off) of a particular line of communication with the controlled object. Other commands that are not destined for him, the control unit 3 transmits to the control unit 3 of the next United with him consistently block 2 control power and data circuits, and so on until the last unit 2 control power and data circuits.

Virtual reference 5 on the basis of the received command generates and transmits a multi-line block 4 comparison signals, the magnitude of the voltage corresponding to the signals of the controlled circuits in digital form during their normal operation.

The imaging unit 8 to output the signals transmits to the circuit of the controlled object pulse and analog signals, the voltage corresponding to the pulse and analog signals interacting with the circuits of the controlled object.

Then, the imaging unit 7 input signals receives signals from the controlled circuits and passes them through the switch 6 to the inputs of the meter 9 voltage and 10 meters of chain.

The meter 9 voltage detects and converts the digital values of the voltages coming from the circuits of the controlled object, and the measuring circuit 10 according to the incoming signals determines there is or there is no break in one way or another circuit, and converts this information into a digital code.

The meter 9 voltage and the measuring circuit 10 transmits the digital signals to a multi-channel unit 4 compare, where they are compared with the signals from the virtual reference 5 in real time. The results of the processing of the signals from the meter 9 voltage and measures 10 circuit by comparing with the signals from the virtual reference 5, is transmitted multi-channel unit 4 comparison of each block 2 control power and data circuits on unit 1 management and control using the control unit 3. On the basis of the results of the signal processing unit 1 management and control decides on the validity of the controlled circuits.

Thus, due to the fact that auto is siromoney test equipment entered the power management and control, the control unit, the switch and the shapers of input and output signals are combined in the block control circuits, functional possibilities of the device, and the presence of several blocks of the control circuit allows to control several circuits of multi-channel communication systems simultaneously.
