Overview

Product overview

Key product information and technical features.

The USB-6008 connects measurement signals directly to a computer through USB, with power supplied by the USB bus. Its lightweight enclosure and screw-terminal signal connections suit portable measurement setups and introductory laboratory work.

Analog input configuration determines both channel count and resolution: differential measurements provide four channels at 12 bits, while single-ended measurements provide eight channels at 11 bits. The maximum 10 kS/s input rate is aggregate, not per channel.

USB bus power supports portable operation without a separate device power supply.
Screw-terminal connectivity provides direct access to sensors and signals.
Two 12-bit analog outputs support software-timed updates up to 150 Hz.
Digital lines can be individually configured as inputs or outputs.
NI-DAQmx provides device configuration and measurement support.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the USB-6008 a 14-bit DAQ device?

No. The USB-6008 provides 12-bit differential and 11-bit single-ended analog input resolution. The USB-6009 is the 14-bit model.

Does 10 kS/s apply to every analog input channel?

No. The specified maximum is 10 kS/s aggregate across the acquired analog input channels and is system dependent.

Are the analog outputs hardware-timed?

No. The two analog outputs are software-timed, with a maximum update rate of 150 Hz and a 0 to +5 V output range.

Which accessory kit is documented for the USB-6008?

NI lists the USB-6008/6009 Accessory Kit, part number 779371-01, containing four additional screw-terminal connectors, connector labels, and a screwdriver.
