4. Linearity calculations on the ATX7006

ATX7006


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:

  • CALCOPT_LIN_AD : Best fit/End point calculation ADC test, trip-point search method, ramp clipping.
  • CALCPARAM_LIN_AD : ADC parameters, applied input signal parameters.
  • CALCPARAM_LIN_AD_EXT : 1/2 LSB offset shift, interface offset and gain parameters.
  • CALCOPT_LIN_DA : Best fit/End point calculation DAC test.
  • CALCPARAM_LIN_DA : DAC bits, applied input signal parameters, interface offset and gain parameters.

Results are available with the commands:


ATX7002


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.

Software/ATView

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".
