CF-5200 Frequently Asked Questions
Question number FAQ-0542
Amplitude flatness and full-scale accuracy refer to the values obtained when converting an accuracy of ±0.1dB to linear voltage when a sine wave with a single amplitude of 1V is input.
(1) Full-scale accuracy ±0.1dB (at 1kHz) refers to the accuracy of each voltage range of the amplitude relative to the full scale.
(2) Amplitude flatness ±0.1dB refers to the reading accuracy of the amplitude at each point in the frequency range resolution of the analysis range.
(3) When converted to a linear voltage of 1V, it is 1.0116V, approximately 1.16%
Calculation formula 0.1dB=20Log(x/1v) x=1.0116
