Introduction

USB-4702 and USB-4704 are low-cost USB data acquisition modules that can be installed without opening the chassis; simply plug in the modules to access collected data. Reliable

and rugged enough for industrial applications, yet sufficiently affordable for home systems, USB-4702 and USB-4704 DAQ modules provide an easy and efficient means of adding

measurement and control capabilities to USB-capable computers. Additionally, because USB-4702 and USB-4704 draw power from the computer via the USB port, no external power

connection is required, making these modules the most cost-effective solution for testing and measurement applications.

Max. Sampling Rate

USB-4702: 10 kS/s max.

USB-4704: 48 kS/s max.

Note: The sampling rate of each channel is influenced by the number of used channels.

For example, if 4 channels are used, the sampling rate will be 10k/4 = 2.5 kS/s per channel.
