OSCILLOSCOPE MEASURING METHOD
PROBLEM TO BE SOLVED: To perform a plurality of measurements with a real time oscilloscope. SOLUTION: Required setting of the oscilloscope is performed, and a 10GBASE-T signal is taken (step 10). Spectrum analysis of a waveform is performed, but two peak values of tone frequency are found, and a thi...

| description | PROBLEM TO BE SOLVED: To perform a plurality of measurements with a real time oscilloscope. SOLUTION: Required setting of the oscilloscope is performed, and a 10GBASE-T signal is taken (step 10). Spectrum analysis of a waveform is performed, but two peak values of tone frequency are found, and a third peak is found on a spectrum (steps 12 and 14). The spectrum level between a tone of low amplitude and the third peak level is measured, and SFDR is measured (step 16). Next, in step 18, a measured value is compared with the limit value which is reached based on the identified tone frequency, and acceptance or disqualification is determined (step 18).
