Description
ч тьс - 2,3т, где т - посто нна времени 1нтегратора. По истечении указанного времени блок 6 управлени поочередно возбуждает основные управл ющие входы ключей 4, в результате чего измеритель 5 подключаетс поочередно к выходам цепей. Поскольку врем измерени на oднoJM спектральном канале составл ет доли миллисекунды, а число спектральных каналов обычно не более 50, то общее врем опроса всех спектральных каналов (50 мс) значительно меньше времени усреднени .h is 2.3t, where m is the time constant of the 1n integrator. After the specified time has elapsed, the control unit 6 alternately excites the main control inputs of the keys 4, as a result of which the meter 5 is connected alternately to the circuit outputs. Since the measurement time on a single JM spectral channel is fractions of a millisecond, and the number of spectral channels is usually no more than 50, the total survey time of all spectral channels (50 ms) is significantly less than the averaging time.
Таким образом длительность цикла измерени определ етс практически временем установлени показаний. В данном зстройстве, это врем равно 2,3т, в то врем , как известное устройство при равных услови х требует времени более 8т.Thus, the duration of the measurement cycle is determined practically by the time of setting the readings. In this disease, this time is 2.3 tons, while, as a known device, under equal conditions, it takes time more than 8 tons.
Устройство обладает еще одним преимуществом перед известным: погрешность от недостаточного установлени показаний в нем ие зависит от величины сигнала в предыдущем цикле измерений и может быть учтена при калибровке прибора, так что результирующа погрешность измерени уменьшитс . В известном устройстве при переключении с большого сигнала на малый погрешность зависит от величины предыдущего сигнала и не может поэтому быть учтена при калибровке прибора. The device has another advantage over the well-known one: the error due to insufficient establishment of indications in it does not depend on the signal size in the previous measurement cycle and can be taken into account when calibrating the instrument, so that the resulting measurement error decreases. In the known device, when switching from a large signal to a small error, it depends on the magnitude of the previous signal and cannot therefore be taken into account when calibrating the device.
