Frequency inputs from GTE

Frequency inputs are characterized by a range of y from the measured frequency of the input signal, the amplitude range, hysteresis value zero-body frequency signal filling etc., And digital inputs Ofsted - the number of digital lines, the values ​​of voltage and current of high and low.

The signals are transmitted in digital form to the bench computer for further processing. The result of the primary processing unit is a parameter estimate obtained with the required level of confidence. It identifies the probability characteristics: expectation, variance and confidence interval of the measurement result. Based on a priori information about the statistical characteristics of the signal processing is performed in the IR pulse interference and measurement failures which increases stability ratings.

Secondary data processing implements and indirect cumulative measurements and is aimed at the characterization of ACS units.

Measuring the information in tabular and graphical form on the screen of the electronic display, recorded and printed and plotters as machine protocols. Archiving test results in databases by using magnetic drives (NMD) and optical (GCD) drives with the appropriate software.

With the development of microprocessor technology began to be used on the stands distributed measurement systems, which integrates a number of functions in a single device - smart sensors.

It has output digital code - the measurement result transmitted to the main computer using one of the standard interfaces: RS-485, CAN, and others. The architecture of IIS has several advantages: increased accuracy and reliability, improved noise immunity.
