Hardware features

 8 single-ended, 16-bit, simultaneous analog input channels, numbered 0 to 7.

Analog voltage input ranges:

o ±10V

o ±5V

o ±2V

o ±1V

 Sampling rate:

o 100 kS/s max rate for one channel

o 400 kS/s max aggregate rate, streaming. Limited by USB transfer speed; 800 kS/s max to 32K

sample FIFO

o Channel-gain queue:

Eight elements - one gain element per channel.

 8 DIO, individually configurable

 External digital trigger

 Bidirectional external clock

 32-bit event counter

 1024 bytes of nonvolatile EEPROM memory; used for storing configuration information, calibration

data, and user data.

 Bulk transfers:

o The bulk in max packet size is 64 bytes.

o The bulk transfer size must be a multiple of the USB maximum bulk packet size.

o Bulk transactions are complete when a packet is sent that is less than the max packet size.

When sending an integer multiplier of the max packet size of data during a transaction, include

an empty packet to indicate the end of the transaction.
