Figure 1 presents a block diagram of a stand. The stand contains (test, figL) the tested controller 1, the input of which is connected to the output of the output transducer 2, the input of which is connected to the output of the electronic bench model S, in contrast to the prototype, the output of the controller 1 is connected to the input of the galvanic isolation unit 4, the first output of which is connected to the input of the buffer control circuit 5, the second output is connected to the first (control) input of the key 6, the second input of the key 6 is connected to the output of the clock generator 7, the output of the key 6 is connected to the input of the counter block 8, the output of which is connected to the input ohm of the buffer block 9, the control input of the buffer block 9 is connected to the output of the buffer control circuit 5, the output of the buffer block 9 is connected to the input of the electronic bench model 3.

to byak Gayavashchetche (junction 4, where it is decoupled and converted to the TTL level. The signal from the galvanic isolation block 4 controls the key 6, the input of which receives pulses from the clock generator 7. Through the key 6, these pulses are fed to the input of block 8 , at the output of which a sixteen-digit code is generated, equivalent to the duration of the signal from the galvanic isolation block 4. This CODE: by signal, the control circuit buffer 5 is entered into buffer block 9 and then read to the electronic stand-by mode News 3. A digital signal from the electronic bench model 3 is sent to the output converter 2. The sensor works in a simple way, where it is converted to an analog signal, which is fed to the regulator 1. Regulator 1, based on the signal level, outputs from the output transformer 2 pulse width modulated: signal.
