NI 9401 specification 100ns



I have got a simple question about the specification of NI 9401. What does the "100ns" of NI 9401 means? I know 100ns refers to 100 nanosecond but what is it about? Is it a sample rate? Or rise time? Or something else?


Please help me.

The maximum clock rate is 10MHz, the inverse of this is 10ns.

Hi Trainee123,


This specification refers to the maxim speed at what you can actually read or write to a digital line of the module. That means that  It would take you at least 100 ns to turn a digital output of the module ON or to turn it OFF.

Your program, the hardware you use ( FPGA, cDAQ, etc..), OS, etc...  affect the final execution time but you should consider the hardware/module  limitations as well before deciding what module is appropriate for your application.
