An example embodiment of the device

The tuning and control unit (BNK) is a part of the technological hardware-software complex for recording and synthesis of radio signals (AIC PC) for debugging workplace equipment of the Republic of Moldova.

The setup and control unit of the BNK (Fig. 1) contains a docking board 1, a matching board 2, a synchronization submodule 3, limit resistors R1 and R2 (4, 5), a toggle switch 6, single indicators HL1 7 and HL2 8, fuses FU1 9 and FU2 10.

Purpose and composition

The tuning and control unit (BNC) is designed to configure and control the subsystem for recording radio engineering signals (PR RTS) and the synthesis subsystem for radio engineering signals (PS RTS).

The composition of the BNK includes:

- Docking board BNK 1;

- coordination card BNK 2;

- synchronization submodule BNK 3;

- fuses FU1 and FU2 9, 10;

- single indicators HL1 and HL2 7, 8;

- toggle switch 6;

- a set of cables;

- special software as part of the BNK management program.

During operation, the BNK must be connected to the COM port of a personal computer 16.

The BNK is supplied from a laboratory power supply with a voltage of +5 V 17.

Device and work

The principle of the BNK is to simulate the signals entering the registration and synthesis subsystems from the cabinets RA-62, RA-45 and RA-31 of the RM product (workstation), simultaneously with the registration and transmission to the personal computer of the signal values generated by the hardware and software subsystems complex registration and synthesis of signals (APK PC).

When power is turned on, the BN synchronization submodule generates 120 MHz paraphase signals and that simulate coherent local oscillator signals used to synchronize subsystems. From the same signals, a 15 MHz signal is generated, which is used to synchronize the BNC matching board.

The approval bullion 2 BULL performs the following functions:

a) generates signals reflecting the structure of the generated sequence of probing pulses (IMAGE START IMPULSE (INC), two-digit REPEAT FREQUENCY CODE KFп, 1 MHz);

b) generates signals simulating the transfer of service information (prefix codes and hyperprefixes) between the cabinets RA-62 and RA-45;

c) registers the values of the signals transmitted by the interface modules of the registration and synthesis subsystems in the cabinets RA-62 and RA-45;

d) generates a signal simulating an echo signal;

e) transfers the codes of the registered data to a personal computer via the RS-232C interface.

Docking board 1 BNK receives and transmits signals PREFIX NUMBER CODE (KNPref) and PREFIX CODE (KPref), generated and received by the registration and synthesis subsystems through the connectors MS19-45 12 and MS19-62 11.

BNK provides the formation of a cyclic sequence of information signals (review cycles). Each cycle consists of a continuous sequence of 1024 frames.

Each frame simulates a pack of 162 probe pulses, the period of which can be programmatically set to 59, 60 or 69 μs, and echo signals from these probe pulses. The beginning of the frame is marked by the formation of an INC pulse

1 μs long and generating a KFp code in accordance with the set period value.

The echo signal generated by the BNK is a rectangular radio pulse with a duration of 4 μs, a carrier period of 5 MHz and an amplitude of 0.5 V. The echo signal is delayed relative to the corresponding probe pulse by 30 μs.

Synchronously with the pulse, the Echo SIGNAL of the BNK generates a pulse STARTING THE GENERATOR (ZPG) with a duration of 4 μs, which can be used to synchronize the oscilloscope when observing the shape of the echo signals or to start an external generator for generating echo signals.

In each frame, the BNK generates 32-bit service information codes (prefixes or hyperprefixes). The hyperfix code is generated after nine prefix codes. Service information formats are presented in table 1.

- 0РКβ _T -10РКβ _T is the eleven-bit azimuth code КβТ, which is calculated by the formula mod2048 (Kβa + 4);

- 0PKFn, 1PKFn - CODE OF THE REPEAT FREQUENCY KFп, taking values 1, 2, 3.

In the middle of each frame, the BNK gives prefix and hyperprefix codes in the form of a sequence of four-digit syllables PREFIX CODE (CPREF) simultaneously with three-digit codes PREFIX NUMBER CODE (KNPREF) indicating the syllable number.

The BNK also registers these codes, translated by the interface modules of the registration and synthesis subsystems of the AIC PC. The directions of the transmission of the CPREF and KNPREF codes between the BNK and the subsystems corresponding to the nature of the exchange of information between the RA-62 and RA-45 cabinets are shown in Fig. 1.

The data exchange rate between the BNK and the personal computer via the RS-232C 16 interface is 115200 bps.

BNK can work in three modes:

- “Initial reset”;

- “Control of the registration subsystem”;

- "Control of the synthesis subsystem."

The switching of modes is carried out by transmitting from the computer bytes of the commands shown in table 2.

table 2 Team Discharges 7 6 5 four 3 2 one 0 "Reset" x x x x one 0 0 0 "Control PR" 0 n n n one 0 0 one "PS control" 0 n n n one 0 one 0

Where x is the discharge value is indifferent, nnn is the code of the sequence of changing the period of the repetition rate of the Raman frequency (nnn = 0, 1, 2 - the period is 59, 60, or 61 μs, respectively, in all frames; nnn = 3, 4, 5 are the alternation of period values, respectively 59 and 60 μs, 60 and 61 μs, 59 and 61 μs, and in even frames a shorter period is always set).

The BNK switches to the “Initial reset” mode when the power switch 6 is turned on or after the “Reset” command is received from the computer. In this mode, pulses are continuously generated by the synchronization submodule, as well as ITKPA pulses (1 MHz) and FRAME START IMPULSES (INC), the KFp code is 1, the KNpref and Kpref codes are not generated.

The BNK switches to the "Control of the registration subsystem" mode after receiving the "PR control" command from the computer.

In this mode, pulses are continuously generated by the synchronization submodule, as well as pulses of ITKPA (1 MHz) and FRAME START IMPULSE (INC), the code KFп is switched in each frame in accordance with the value of the parameter nnn specified in the command.

In the middle of each frame, the BNK generates a sequence of KNPref and Kpref codes transmitted to the registration subsystem. At the same time, sequences of codes KNPref-62 and Kpref-45 are recorded, which are generated by the interface module of the MS registration subsystem.

The registered data is transmitted to the computer in the format shown in table 3.

The operation of the BNK will continue until the receipt of the Reset command.

The BNK switches to the "Control of synthesis subsystem" mode after receiving the "Control of PS" command from a computer.

In this mode, pulses are continuously generated by the synchronization submodule, as well as ITKPA pulses (1 MHz) and FRAME START IMPULSE (ITK), the KFп code is switched in each frame in accordance with the parameter nnn of the command specified in the command.

In the middle of each frame, the BNK generates a sequence of KNPref codes into the synthesis subsystem. At the same time, sequences of codes KNPref-62 and Kpref-45 are recorded, which are generated by the interface module MS1 of the synthesis subsystem.

The registered data is transmitted to the computer in the format shown in table 3.

The BNK management program provides:

- formation according to the operator’s instructions and transfer of commands to the BNK;

- write to the file the codes received from the BNK;

- display of registered data to the operator;

- Comparison of registered BNC data with patterns and identification of errors;

- Comparison of registered BNC data with data registered by the registration subsystem or generated by the synthesis subsystem.

The BNK management program provides recording on a magnetic disk of the registered BNC data per cycle in the files FilenameMMM.bnk, MMM - the number of the control cycle. The size of this file is 10240 bytes.

Data is transferred from the registration and synthesis subsystems to computers by copying them to flash memory.
