The present invention relates to devices for automated testing, in particular to test devices analog, analog-digital, digital and analog electronic equipment (REE). Can be used for testing (control), diagnostics, configuration and acceptance testing of complex objects of special equipment, which include replaceable functional products (electronic modules). There are many test devices and diagnostic products REA implemented, for example, in: - "Automated diagnostic system digital devices", patent of Russian Federation №2097827 from 27.11.1997, - [1]; - "The functional device control digital nodes, the application for the invention of the Russian Federation No. 95112321 from 18.07.1995, - [2]; - "The diagnostic system of digital devices", patent of Russian Federation №2127447 from 10.03.1999, - [3]; - "Hardware-software diagnostics stand digital and microprocessor units", patent of Russian Federation №2324967 from, 20.05.2008 - [4]; - "Automated diagnostic system", application for a patent of the Russian Federation No. 2007117102 from 07.05.2007, - [5]. However, testing devices and diagnostic products REA on[1], [2], [3], [4] [5] cannot be applied to digital to analog, analog to digital and analog functional products REA complex objects of special equipment. Like,for example, "Device for controlling analog objects", patent of Russian Federation №2262128 from 10.10.2005, - [6], cannot be applied to digital to analog, analog-to-digital and digital functional products REA. Known methods and devices, implement, for automated testing and diagnosis of analog, analog-digital, digital-analog and digital products, such as, for inventions: "The method that control the electrical parameters of the amplifier, the automated control system of electric parameters of an amplifier, RF patent №2212674 from 10.03.1998, - [7], - "Method of synthesis of multiparameter automated measuring systems", patent of Russian Federation №2220435 from 27.12.2003, - [8], - "Method for diagnosis apparatus", patent of Russian Federation №2265236 from 27.11.2005, - [9], - "Systems and methods for providing dynamic modular processing unit, RF patent No. 2386163 from 10.04.2010, - [10]. The common disadvantage of the methods and devices implementing them, [7], [8], [9] and [10] is that they are all particular cases of functional diagnostics products REA complex objects of special equipment, conducted according to Technical conditions (TU) for a specific product. And thus, the above methods and devices, implementing, testing and diagnosis are of limited use. At the same time, we know many of the devices automated testing and diagnosis of analog parameters, analog-to-digital, digital-analog and digital products, for example: - "Automated control of electronic devices", USSR author's certificate No. 1683038 from 07.10.1991, - [11], - "Automated control system of parameters of electronic circuits", patent of Russian Federation №2106677 from 10.03.1998, - [12], - "Automatic control system", patent of Russian Federation №2150730 from 10.06.2000, - [13], - "Automatic control system", patent of Russian Federation №2156493 from 20.09.2000, - [14], - "Automatic control system", patent of Russian Federation №2248028 from 10.03.2005, - [15], Device for control of electronic objects", patent of Russian Federation №2324213 from 10.05.2008, - [16], - "Portable software-diagnostic complex", patent of Russian Federation №2363975 from 10.08.2009, - [17], - "Modular diagnostic controller, RF patent №2397469 from 20.08.2010, - [18], - "Automated control and diagnostics (options)", RF patent №2257604 from 27.07.2005, - [19], - "Portable diagnostic system", patent of Russian Federation №2340926 from 10.12.2008, - [20]. A common disadvantage of the above devices[11], [12], [13], [14], [15], [16], [17], [18], [19] and [20] is that they are all designed for testing and diagnosis of specific products and do not have wide use for the diagnosis of various functional components REA complex machines special applications, Provo is imich according to Technical conditions (TU) for a specific product. The prototype of the present invention is a device for automated testing of analog, analog-digital, digital-analog and digital products, as implemented in full control and measuring system (or other words) in the module test unit (MTU), for example, National Instrument: http://www.ni.com/russia - [21]. This prototype [21], a device for automated testing of analog, analog-digital, digital-analog, digital products, contains the MTU of the power supply modules, modules, switches, modules issuance and modules receive analog and digital signals, is connected to the internal bus MTU, embedded computers, control modules via the internal bus MTU, as well as the tested product. All modules have a standard MTU for computers and devices, power supplies, switches, issuing and receiving analog and digital signals connectors, which connect via cables tested the product. The disadvantages of the prototype is that often tested the product has non-standard connectors and connection modules MTU causes certain difficulties, that is, requires additional material and most importantly time. This is especially true for products REA complex objects of special equipment, which is s may not be consistent with the modules MTU. In addition, testing and diagnostics products REA complex objects of special equipment must be strictly in accordance with the specifications for a specific product, what MTU [21] to achieve in its submitted form (without additional hardware-software complex) can not. Proceeding from above-stated disadvantages, the tasks that follow from the necessity of applying for testing and diagnostic products REA complex objects of special equipment known MTU, the following: - significant reduction in testing time of the product (or diagnosis, in case of failure to perform the test), then there is a significant reduction in the time control measurements and their comparison with the reference; - reducing the complexity of testing and diagnostic products REA with the creation and issue a comprehensive report control measurements; - increased versatility used for testing and diagnostic equipment for the entire series of articles REA included in the composition of complex objects of special equipment. These problems are solved (the essence of the invention)that in the device for automated testing of analog, analog-digital, digital-analog and digital products containing unit test unit (MTU), consisting of modules (the s power, modules, switches, modules issuance and modules receive analog and digital signals, is connected to the internal bus MTU, embedded computers, control modules via the internal bus MTU, and tested the product, added front-end module with hardware-software complex negotiation MTU and tested products, the interface module contains a first group of standard connectors to connect to the modules MTU and the second group of standard and custom connectors for connection to the tested product, with the inputs and outputs of the modules MTU connected by cables to the inputs and outputs using standard connectors of the first group of interface module and tested the product by means of standard and custom connectors and cables are connected to the inputs and outputs of the second group of the interface module. The introduction of additional interface module with hardware-software complex negotiation MTU and tested products" need to reconcile the specific items REA complex objects of special equipment with standard modules MTU that allows the best and least time-consuming to configure the MTU for testing and diagnostics products REA. Introduction distinguishing characteristics: "the interface module contains a first group of standard connectors for under the your modules MTU" and "the inputs and outputs of the modules MTU connected by cables to the inputs and outputs using standard connectors of the first group of interface module is necessary only once (when testing series of single products REA complex objects special technique is relatively time-consuming connecting the interface module to the modules MTU. The introduction of a distinction: "the interface module contains a second group of standard and custom connectors for connection to the test product and the test product using standard and non-standard connectors and cables are connected to the inputs and outputs of the second group of interface module you want to test a series of identical products CEA their quick replacement, which will significantly reduce the complexity of testing and diagnostic products REA complex objects of special equipment. In General, the application of the proposed device further enhances the versatility of the prototype testing and diagnostics for the entire series of articles REA included in the composition of complex objects of special equipment, as a replacement interface module for a particular series of test items REA creates the ability to quickly and effectively test another series of test items REA. In memory built-in computer MTU is initially the composition, sequence and number of signals diagnostic parameters of the product according to the technical requirements defined in the technical the economic conditions of the test and diagnostics products REA. 1 schematically shows a device for automated testing of analog, analog-digital, digital-analog and digital products. Figure 2 shows the block diagram of the operation of the device. Figure 3 is an example of a control panel interface tests built computers MTU. Figure 4 - result of the test: check the noise level and regular components of the signal spectrum “fLC AR” and “fLC PR”(Spectral component of the noise cells in AP mode). Figure 5 is the result of the test: Test the attenuation of signals flC AR” and “fLC PR”(Output signal of the cells in AP mode). Figure 6 - the result of the test: Test the attenuation of signals flC AR” and “fLC PR”(Noise signal cells in the absence of the output signal in AP mode). The device contains 1 MTU (1) modules (2) - (modules, power supplies, modules, switches, modules issuance and modules receive analog and digital signals), which are connected to an internal bus (3) MTU, as well as a built-in computer (4), the control module (2) via the internal bus (3) MTU, and test the product (5). In the device additionally introduced interface module (6) with hardware-software complex (hardcoded in ROM interface module) MTU negotiation (1) and the test product (5), the interface module (6) contains the first group of standard connectors to connect to the fashion of the holes (2) MTU and the second group of standard and custom connectors for connection to the test product (5), while the inputs and outputs of the modules MTU connected by cables (7) with inputs and outputs using standard connectors of the first group of interface module (6), and test the product (5) using standard and non-standard connectors and cables (8) connected to the inputs and outputs of the second group of interface module (6). The proposed device can be explained by the block diagram of its operation, is shown in figure 2. Initially, the composition and number of signals for testing and diagnostics of parameters of the tested products (5) REA chosen according to the technical requirements defined in the technical specifications of the product (5), and under the selected signals and the specified requirements linked to the composition and number of modules (2) ITA (1). Under the settings for a particular interface module (6) and the test product (5) in memory built-in MTU (1) computers (4) written program testing and diagnostics. Field connections to the modules (2) ITA (1) cables (7) with standard connectors interface module (6) and to the interface module (6) using non-standard connectors and cables (8) good (5) should include program testing. When a program is enabled testing of the product (5) computers (4) bus (3) manages the modules (2), which generates test signals transmitted through the interface module (6) of the tested product (5), the response which signals through the interface module (6) go back to the modules (2) ITA (1). The modules (2) ITA (1) accept the received signals, process them and on the bus (3) is sent to the embedded computer (4) for final processing. Thus the sequence and the number of signals of the test parameters of the product (5) meets the technical requirements defined by the technical specifications for the product (5) of the CEA. If the testing is within accepted tolerances, built-in MTU (1) computers (4) gives the result (minutes) test, recording it in the memory and displaying it on the monitor screen or on paper (the printer). If the test results fall outside accepted tolerances, using the built-in MTU (1) computers (4) diagnostics products (5) automatic or manual step-by-step mode (if in automatic mode diagnostic products REA was unable to identify a fault with the issuance of the diagnostic results. As one example of the creation and application of the proposed invention, it is possible to cause the device to diagnose cell (e-module) product CEA complex object of special equipment, namely cells of the DIV according to the specifications ITU. Conducted automated testing (verification) testing time readiness cells and delivery of ready signals, checking the spectral characteristics of the output signals, the scan time to ascertain the Oia frequency signals fLC AR” and “fLC PR” with the change applied to the cell code, check the ratio of the frequency of the signals fLC AR" and "fLC PR" f/10 the DIV mode recipe, check signal "TUPG" when a multitude of codes. So when checking the attenuation of signals fLC AR” and “fLC OL ' proposed by the present invention using the MTU interface module tested products - devices (cell DIV), when submitting 3 stress takes about 3 hours, and check the cell by conventional methods takes 8÷9 hours. At the same time to ensure the testing (diagnosis) of this product - cell without the use proposed by the present invention, there is a stand of the control parameter value of about 1.5-2 million rubles. The proposed device allows to reduce the time of testing and diagnosis, repair and development of products forming part of a complex of objects of special equipment, and can reduce the costs of product development, eliminating the need for the development of special stands test and diagnosis (control) for each series of products. We believe that the proposed testing device parameters analog, analog-digital, digital-analog, digital products has all the criteria of the invention, since the combination of restrictive and distinctive features of the claims is new to tester the cation and diagnostic products REA complex objects of special equipment and therefore, meets the criterion of "novelty"; - A set of features in the claims the device for automated testing of analog, analog-digital, digital-analog, digital products is not known at this level of technology and does not follow the conventional rules of diagnostics products REA complex objects of special equipment, which proves the compliance with the criterion of "inventive step"; - The introduction of the proposed device for automated testing of analog, analog-digital, digital-analog, digital products do not present any constructive technical and technological difficulties, whence it follows that the criterion of "industrial applicability".
