Hence, ENOB (Effective Number of Bits) is calculated by RMS Noise and Full Scale Range ratio. However, RMS Noise must be calculated by many average times. Insufficient sampling times can only represent RMS Noise for a specific period of time instead of the RMS Noise of the entire ADC operation. Therefore, RMS Noise operation times cannot be less than 1024 times. . However, Noise Free Bit represents that ADC output value count is not rolling. Noise Free Bits are stable ADC output performance. Bit operation is defined as Peak-to-Peak Noise and Full Scale Range ratio. RMS Noise Calculation: n Average Counts Average ADCk k 1 n Equation 3 n = Total ADC sampling times. 2 n RMS Noise VREF ADCk Average k 1 n 2Scale Equation 4 Scale = Total ADC Output Bits Peak-to-Peak Noise Calculation: Peak - to - Peak Noise VREF ADCMax ADCMin 2Scale Equation 5 ADCMax = Maximum ADC value of total sample ADCMin = Minimum ADC value of total sample © 2012 HYCON Technology Corp www.hycontek.com APD-DMM004-V02_EN page 5 HY12P65 ENOB Test Tool User Manual 1.4 Window Interface When the software is opened, the window in below will pop up, as Figure 1- 2: Setup USB Scan Read all registers ENOB & Noise Free Test Test Ranges USB Connect Status Figure 1- 2 1.4.1 Option .
