Automation of processing of measurement results of parameters of precision frequency measures

The method of measuring of the parameters of precision frequency measures with the help of the frequency comparator CH7-308A/1 is presented, which compares the phase difference between the researched and the reference signals. The use of the CH7-308A/1 frequency comparator software and the software tools of the integrated Microsoft Office suite allows you to automate the processing of measurement results for precision frequency measures, to determine the relative frequency difference and frequency instability characteristics of the frequency and time signals. The advantages of this method are the ability to select measuring intervals from 1 s to 1 day or more. The method ensures automatic saving of measurement results and their long-term storage, easy search in the history of measurements by date and name of the measuring instrument, the ability to separate the time of observation for any periods and carry out their separate analysis, and, most importantly, to save the measurement results of the phase difference of the test and reference signals, for example, every second, in the form of a single file, which is easily transformed into a spreadsheet. This enables independently, using application software tools, to calculate the relative frequency difference between the researched and reference signals and the characteristics of the instability of the researched signal. Proposed methods of processing a series of numbers, which is a phase difference between the researched and reference signals, can be used not only in processing data from the frequency comparator CH7-308A/1, but also in the processing of data received from other devices, including the frequency meters to compare pairs of signals, such as CNT-90, CNT-91, Agilent 53131A, etc.
