The technical result of the invention is to expand the functionality, increase reliability, improve maintainability. The complex contains workstations and servers connected through a local area network Ethernet and based on personal electronic computers (PCs), as well as controllers and functional modules. Functional (MF) programmable logic integrated circuits (FPGAs) built into each module support the “flashing” of almost any signal processing and control algorithms that are adequate to the tasks that the designer assigns to this module. There are three options for building systems based on the complex: centralized management; local management; distributed management. In all three variants, the central processor module (under software control) performs initial configuration of functional modules, exchange of information, and control and diagnostics of software and hardware.

An automated system for measuring the parameters of a radio station with an output power of up to 2 W (when passing a speech signal) based on a control and measuring system from National Instruments (http://russia.ni.com/sites/default/) can be used as an analogue of the presented PAK; files / sdr.pdf).

The main difference between the PAK and the selected analogue is that in order to be able to control the parameters of radio stations with a power of more than 50 W, an attenuator with normalized characteristics is added to the structure of the PAK, which are taken into account when measuring and recording the output power of the PC transmitter.

The technical result of the proposed utility model is the ability to control the parameters of radio stations with a capacity of over 50 watts.

The specified technical result is achieved by the fact that in the hardware-software complex for monitoring the parameters of R-168-100U radio stations, containing a controlled power source, a current and voltage control device, a transition device, a personal computer, a printer and an interface converter, where the output of the controlled power source is connected to the input devices for monitoring current and voltage, the output of which is connected to the power terminals of the checked radio station, and control signals from a PC connected to a printer to output the test report are received and the corresponding input of the power source through the transition device and to the input of the radio station, a powerful attenuator is additionally introduced, the input of which is connected through the automated control panel to the output of the studied radio station, and the output to the high-frequency input / output of the service monitor, and the service monitor of communications is used as a central control and measuring link.

The operating mode of the radio station, measuring instruments and automated TPs are controlled by means of a PC using the software developed for this PAK.

In the drawing, fig. 1 shows a diagram of a hardware-software complex for monitoring the parameters of R-168-100U radio stations. The hardware-software complex for monitoring the parameters of the R-168-100U radio stations consists of the tested radio station 1, the service monitor for communications 2, the interface converter 3, the automated control panel 4, the error coefficient meter 5, PC 6, printer 7, the current and voltage monitoring device 8 controlled power supply 9, attenuator 10.

PAK works as follows: the tested radio station (1 Fig. 1) is connected to the PAK structure as follows:

- through the power circuit - through a current and voltage control device (8 Fig. 1) to a controlled power source (9 Fig. 1);

- through signaling high-frequency and low-frequency circuits - through an automated control panel (4 Fig. 1) and a powerful attenuator (10 Fig. 1) to the service monitor of communication equipment (2 Fig. 1);

- along the control circuit - to the PC.

When starting the software (software) installed on the PC (6 Fig. 1), the serial number of the radio station (PC) is entered. Next, the parameters of the checked radio station are automatically controlled by software on the PAK.

The parameters of the PC are controlled at three levels of supply voltage, normalized by the technical conditions: nominal, maximum and minimum. The indicated voltage levels are generated by a controlled power source. The values of the supply voltage and the current consumed by the PC are recorded by the current and voltage control device and transmitted to the PC.

The control of the switching modes of the PC is carried out by a PC.

The formation of the testing signals and the measurement of the parameters of the tested PC is carried out by a service communication monitor connected via an interface converter (3 Fig. 1) to a PC, where the values of the measured parameters are transmitted.

The formation of the measuring circuits necessary for testing the RS and the switching of test signals are carried out by an automated control panel. Powerful high-frequency signals transmitted through an automated control panel are transmitted to the service communication monitor through an attenuator that reduces power. The attenuation coefficient of the signal in the attenuator is taken into account by the software when calculating the parameters of the test RS.

When assessing the quality of the radio path of the tested RS when transmitting and receiving encoded signals and telemetric information, the error coefficient meter (5 Fig. 1) is included in the PAC measuring loop, which generates a test pulse sequence and compares with it the pulse sequence transmitted through the radio path of the tested RS (with recalculation in error rate).

In the PC, the measurement results of the PC parameters are processed and a test report is generated, which is displayed through the printer (7 Fig. 1).
