The NI 6555/6556 provides flexible acquisition capabilities for acquiring up to 24-bit wide patterns with programmable voltage thresholds using either an internal or external clock source. The NI 6555/6556 dual-comparator architecture allows for data interpretation based on the acquired voltage level relationship to both the Acquisition Voltage Low and Acquisition Voltage High thresholds. External triggers can control the acquisition operation, and the Pattern Acquisition Engine can route those control signals to be shared with other devices.

Refer to Dynamic Acquisition Clock Sources for information about available clocks for a dynamic acquisition operation.

For information about defining acquisition resources in NI-HSDIO, refer to Acquisition Configuration Functions to learn which VIs and C functions are available for your application.
