NI 5402/5406 Calibration Procedure
4.
Set the output impedance by calling the niFgen Property Node and
selecting
Basic Operation»Output Impedance
.
Repeat steps 5 through 13 for each of the iterations listed in Table 6,
changing the Analog Static Value, Amplitude, and DC Offset values for
each iteration.
