1 SPECIFICATIONSNI cDAQ -91911-Slot, Ethernet and Wi-Fi CompactDAQ ChassisDefinitionsWarranted specifications describe the performance of a model under stated operatingconditions and are covered by the model describe values that are relevant to the use of the model under stated operatingconditions but are not covered by the model warranty. Typical specifications describe the expected performance met by a majority of themodels. Nominal specifications describe parameters and attributes that may be useful in are Typical unless otherwise are valid at 25 C unless otherwise InputInput FIFO size127 samplesMaximum sample rate1 Determined by the C Series moduleTiming accuracy250 ppm of sample rateTiming nsNumber of channels supportedDetermined by the C Series module1 Performance dependent on type of installed C Series module and number of channels in the not include group delay.
