DEVICE SPECIFICATIONS NI 6722/6723

1 DEVICE SPECIFICATIONSNI 6722 / 6723 This document lists the SPECIFICATIONS for the NI 6722 / 6723 analog output devices . The following SPECIFICATIONS are typical at 25 C unless otherwise OutputOutput CharacteristicsNumber of channelsNI voltage outputsNI voltage bits, 1 in 8,192 Maximum update rateNumber of ChannelsMaximum Update RateUsing Local FIFO (kS/s)*Using Host PC Memory (kS/s) * These numbers apply to continuous waveform generation, which allows for the fastest waveform generation because it does not use the PCI bus. The maximum update rate in FIFO mode does not change regardless of the number of devices in the system.

2 The NI 6722 / 6723 does not take any time to reset the FIFO to the beginning when cycling through it. These results were measured using a PCI- 6722 / 6723 DEVICE with a 550 MHz Pentium III machine. These numbers may change when using more devices or when other CPU or bus activity | |NI 6722 / 6723 DEVICE SpecificationsType of , voltageFIFO buffer ,047 samplesDMA , interrupts, programmed I/ODMA InformationTransfer CharacteristicsRelative accuracy (INL)..
