NI 5402/5406 Calibration Procedure
Adjusting the Main Path Pre-Amplifier Offset
1.
Set the main DAC value by calling the niFgen Write Binary 16 Analog
Static Value VI.
Repeat steps 2 through 5 for each of the 10 iterations listed in Table 7,
changing the
Analog Filter Enable
,
Pre-Amplifier Attenuation
, and
Current Configuration
values for each iteration.
