Can any one tell me the Sample Clock frequecy (dt) of a single channel Digital Input of USB6009 when we Read data using Digital Waveform 1 Channel N Sample mode? In the digital waveform received the dt parameter is 0, however all the samples are read at the end of complete acquisition? Is this hardware timed or Software Timed Input, as the read command is given only once per acquisition and all the samples are received automatically? Can this waveform be used for comparison of data received from the Analog Input side? Please reply.

No, the digital input is not hardware timed so there is no signal to use to corellate the data with analog input samples. That requires a device that supports hardware timed digital input.
