Problem: When using VI Logger to sample multiple channels, how do I determine the interchannel delay? Solution: VI Logger allows Traditional NI-DAQ to set the interchannel delay. By default, this is the minimum interchannel delay allowed by your specific DAQ device + a 10 µs pad to account for amplifier settling times. Thus, the typical delay for a particular DAQ device can be determined using the following formula: 10 µs + [1/maximum sampling rate of the device]. However, for faster sampling rates, this 10 µs pad can be decreased and/or eliminated completely. Therefore, iinterchannel delay may vary between different higher sampling rates.
