The sine wave should have a SINAD (signal-to-interference ratio including noise and distortion) value of at leat 75 dBc and an amplitude just above 100 %. Therefore , therefore some clipping occurs and all ADC codes are present in the analysis. The sample length should ensure the average data points per ADC code to be well above 150.
These values are visible in the lower part of the statistic section to the right under DNL / INL statistics: .
An other aid for good results is the input frequency. The construction of the modules leads to a desired input frequency of 101.09 Hz. Best practice is to supply the input signal differentially.BILD EINFÜGEN
Usage
Apply a signal to the modules inputs. Connect a single module to your PC and start the program. Press Connect for a connection to the module. A connection applies the default Gain of 1, enables the buttons Wave/FFT, DNL/INL and the sections Module and Generator.
