Data Mask

The signal generator supports analog and digital data masks and static values. The data mask allows you to shield bits of the data to be replaced with the corresponding static value bits. For example, a mask of 0xFF00 and a static value of 0xAAAA applied to a DC waveform with a value of 0x1111 produces a DC waveform with a value of 0x11AA.

NI-FGEN supports separate and independent analog and digital data masks and static values. The analog data mask and analog static value apply to the digital data applied to the DAC, and ultimately to the signal on the analog output terminal. The analog data mask and analog static value do not affect the signals on the digital connector. For more information about analog masking, refer to the Analog Data Mask or Analog Static Value properties or the NIFGEN_ATTR_ANALOG_DATA_MASK and NIFGEN_ATTR_ANALOG_STATIC_VALUE attributes. The digital data mask and digital static value apply to the signals on the digital connector and they do not affect the signal on the analog output terminal. For more information about using digital masking, refer to the Digital Data Mask or Digital Static Value properties or the NIFGEN_ATTR_DIGITAL_DATA_MASK and NIFGEN_ATTR_DIGITAL_STATIC_VALUE attributes.
