SymClkErr (Digital Demod)

SymClkErr (Symbol Clock Error) is a calculation of the accuracy of the 2-FSK Frequency Shift Keying: A form of modulation using multiple carrier frequencies to carry the digital information. The most common is the two frequency FSK system using the two frequencies to carry the binary ones and zeros. modulation's symbol clock. The symbol clock error is directly calculated from the 2FSK Meas Time trace using multiple FFT Fast Fourier Transform: A mathematical operation performed on a time-domain signal to yield the individual spectral components that constitute the signal. See Spectrum. frequency points. The result is in parts per million (ppm).

The IEEE Institute of Electrical and Electronics Engineers. A US-based membership organisation that includes engineers, scientists, and students in electronics and related fields. The IEEE developed the 802 series wired and wireless LAN standards. Visit the IEEE at http://www.ieee.org standard document defines the acceptable symbol clock frequency tolerance (e.g., 802.15.4g-2102 section 18.2.4.9). If you are measuring for conformance, the symbol clock error should fall within the standard's tolerance.
