A traceable method for measuring modulation error ratio of radio frequency signals
2016
A traceable method for measuring modulation error of radio frequency signals has been demonstrated in this article. This method uses sampling oscilloscope and two quadrature sinusoidal signals generated simultaneously from a continuous waveform (CW) generator to build the measurement system. It improves correlation algorithms and obtains the measurement results accurately. It provides a traceable chain between the MER measurement system and electro-optic sampling system. Experimental results are presented for 16QAM communication schemes.
