Explanation/Annotation:Modulation meter of computing. For operational measurement of module
öèîííûõ signal parameters of communication and instrumentation.
Detailed model description:The device provides the measurement following parameters:
- peak and root-mean-square value of coefficient. amplitude modulation;
- peak and root-mean-square value of frequency deviation;
- voltage and frequency of high frequency signal;
- harmonic coefficient of baseband signal;
- peak and root-mean-square value of dollar exchange of sensor signal phasic
modulating (PM);
- frequencies of baseband signal;
calculations of measuring results and their correcting is produced in
digital form. In device is provided logarithmic counting off èçìåðÿ-
åìûõ sizes. It has the total automation of measurement processes and êà-
ëèáðîâêè and may to be used in computer-based measurement ñè-
ñòåìàõ ( computer-based information systems), as well as carries out failures diagnostics.
in device is provided the possibility of work with plug-in module
