The aim of the invention is to develop a device to convert the time scale of signals having a wide frequency range.

The objective is achieved by the fact that the Converter temporal scale signals containing series-connected to the analyzer input mixer, amplifier, adder, and connected in series sensor with the sample and the output amplifier, with the input of the analyzer is connected to the input bus, the output of the first generator with linear frequency modulation pulse is connected to a second input of the mixer, the output of the second generator with linear frequency modulation pulse is connected to the second input of the adder, additionally introduced programmer, the first and second power amplifiers, the third generator with linear frequency modulation pulse, and the sensor is made in the form of two mutually perpendicular coils, which is located inside the sample containing quadrupolar nuclei with three-level netvigilance energy spectrum, and the first power amplifier connected between the adder and the first coil of the sensor, the input of the programmer is connected to the second output analyzer input signal, first, second and third outputs programmatie pulse, a second amplifier connected between the third generator with linear frequency modulation pulse and the second coil of the sensor.

In Fig. 1 shows the structural diagram of the Converter temporal scale signals; Fig. 2 shows time diagrams of the device.

The device contains the analyzer 1 of the input signal, programmer 2, mixer 3, the first generator 4, the chirp pulse, the amplifier 5, an adder 6, the second oscillator 7, the chirp of the pulse, the first amplifier 8 power, a third generator 9, the chirp pulse, the sensor 10 with the sample, the second amplifier 11 power and the output amplifier 12.

The device operates as follows.

At the analyzer input input 1 signal durationI. At the output of the analyzer 1 will receive a range of signal duration on the time axis, is equal to

CR=f/K1< / BR>
where K1conversion;

f width of the spectrum of the input signal.

This signal is fed to the first input of the mixer 3, the second input of which is applied the pulse with linear frequency modulation (chirp) with the output of the first generator, the chirp of the pulse. At the output of mixer 3 is formed a signal with linear frequency fashion the raised voltage of the second generator 7, the chirp of the pulse. From the output of the adder 6 received two-pulse sequence is fed to the input of the first amplifier 8 power, where it is amplified to the required size (capacity). The output voltage from the first power amplifier is fed to the first coil of the sensor 10 with the sample. The average fill rate of two chirp pulses should be equal to the frequency of one of the three-level transitions netvigilance quadrupole spin system (at the same time and the average frequency of the signal). On the second coil of the sensor 10 receives the chirp pulse from the output of the second amplifier 11 power input of which receives the chirp pulse with an output of the third oscillator 9, the chirp of the pulse. The average fill rate, the chirp of the pulse should be equal to the frequency of the second three-level transition netvigilance spin system.

Two sensor coil 10 is made so that their keywords. fields are mutually perpendicular, and this should be done mutually perpendicular coils. Inside them is a sample containing quadrupolar nuclei with three-level netvigilance energy spectrum.

All three generators, the chirp pulses are triggered by the programmer 2. The start time of each of the generator depends on the pulse PR tilt modulation characteristics of the generator 4, you can control the conversion device, and it is also possible to change the sign of the transform (some part of).

When the dual impact of advanced conversion factor still depends on the excitation conditions (i.e., the pulse program, for example, as in Fig. 2A, b) and select the frequency of excitation. When this conversion may optionally vary the magnitude of the ratio of two frequency excitation to a value , where cthe frequency of the signal.
