In FIG. 1 and 2 presents a block diagram of the proposed device.

The device comprises a range selection blocks 1 and 2, pulse counters 3 and 4, comparison blocks 5 and 6, an actuator 7, control action memory blocks 8 and 9, a pulse generator 10, a test object 11, an analog-to-digital converter 12. block 13 memory of the response signal of the object, digital-to-analog converter 14, comparator 15, control unit 16.

The first outputs of the range selection blocks 1 and 2 are connected respectively to the inputs of the preset counters 3 and 4 of the pulses, and the second outputs are connected to. the first inputs of comparison blocks 5 and 6, respectively. The outputs of the counters 3 and 4 are connected to the inputs of the actuator 7 and, respectively, to the information inputs of the control memory block 8 and 9 and the second inputs of the comparison blocks 5 and B. The output of the comparison block 5 is connected to the write enable input of the pulse counter 3 and the summing input counter 4 pulses, and the output of block 6 comparison with the input of the pulse generator. The input of the test object 11 is connected to the output of the actuator 7, and its output is connected to the inputs of the analog-to-digital converter 12 and comparator 15, The output of the analog-to-digital converter 12 is connected to the information input of the object response signal memory unit 13. The output of the response signal memory unit 13 via a digital-to-analog converter 14 is connected to the second input of the comparator 15. The output of the comparator 15 is connected to the write enable inputs of the control action memories 5 and 6 and the object response signal memory unit 13.

The device operates as follows.

Before operation, the control memory blocks 5 and b and the object response signal memory block 13 are cleared. On the range selection blocks 1 and 2, numbers corresponding to the lower and upper limits of the range of parameters of the acting signals are set. The lower values of these parameters are entered respectively in the counters 3 and 4 of the pulses, and the upper values are sent respectively to blocks 5 and 6 of the comparison.

Each pulse coming from a 10-pulse generator to a 3-pulse counter increases by one the number entered in this counter. When this number reaches the value corresponding to the upper boundary of the first signal parameter, the comparison unit 5 generates a pulse, which overwrites the original number into the pulse counter 3 and increases by one the number entered in the pulse counter 4. This process is repeated until the number entered in the pulse counter 4 reaches the value corresponding to the upper boundary of the second signal parameter. The signal from the output of the comparison unit b prohibits further operation of the pulse generator 10. In this way, all values of the first signal parameter within the range set in the range selection unit 1 are automatically enumerated relative to each value of the second signal parameter defined by the range boundaries set in the range selection unit 2.

When the signals from counters 3 and 4 of the pulses arrive at the actuator 7. The signal from the output of the actuator 7, the parameters of which are set by the control codes, goes to the object under study 11. The response of the object under study 11 in the form of an analog signal is sent to the analog a digital converter 12 and the first input of the comparator 15. If the voltage at the first input of the comparator 15 exceeds the voltage at its second input (which is zero in the initial state), then the output signal from the comparator 15 is written to blocks of 8.9 pa minute and the actuating unit 13 influences the memory object's response signal. In blocks 8 and 9 of the memory of the control actions, codes of numbers corresponding to the values of the first and second parameters of the acting signal at a given time are respectively entered. In block 13 of the memory of the response signal of the object, a code of the number corresponding to the signal from the test object 11 to the input of the analog-to-digital converter 12 is entered. From the output of block 13 of the memory of the response signal of the object, the entered code is input to the digital-to-analog converter 14, where it is converted the voltage applied to the second input of the comparator 15. A constant voltage level is maintained at this input until the number entered in the memory unit 13 of the response signal of the object is overwritten, i.e. as the signal from the test object 11 increases. The process of overwriting information in control memory blocks 8.9 and in the memory block 13 of the response signal of the object stops when the response reaches the maximum value of the test object 11.

Thus, in blocks 8 and 9 of the memory of the control actions, the values of the first and second parameters of the acting signal at the time of the maximum response of the test object 11 are recorded respectively, and the value of this maximum response is entered in the block 13 of the response signal of the object.

Input and storing by the device of the boundaries of changes in the parameters of the acting signal of the actuator 7 is carried out in manual control mode. On blocks 1 and 2 of the range selection (using, for example, switches of type PP-10), the values of the lower and upper bounds of the parameters of the acting signal are accumulated in the decimal code. By pressing the Record button these values are entered into the counters 3 and 4 of the pulses. As counters with preliminary recording of numbers, for example, K155IE6 microcircuits can be used. In the pulse counter 3, the second input is a write enable input, and the third is a summing input. In the pulse counter 4, the second input is a summing input.

For example, any standard microwave generator having inputs for remote control of frequency and power and providing generation in the required frequency range can be used as an actuator 7. Comparison units 5 and 6 can be performed, for example, on 562 IP2 chips by cascading or pyramidal connection thereof.
