The linearity calculations can be performed on the ATX7006 with the command CALC_LIN. Linearity calculations can be performed on captured data from a DIO module (A/D converter test) or a WFD (D/A converter test).
The linearity calculations can be configured with the commands:
Results are available with the commands:
Calculations will be performed after a test (MX) when the system is in "production mode". The system is set in production mode with the command PMODE. Linearity calculations are performed after a ramp test, MT1 (A/D test) or MT11 (D/A test). Results can be queried with the command M.
The WaveAnalyzer of ATView7006 is also capable of doing a linearity analysis. Press the corresponding button (B.FIT), TUE, ENDP, etc.). Settings can be adjusted from the menu "Options" -> "Linearity Measurement Settings".
