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