USB Data Acquisition DI-1100
DATAQ DI-1100 USB Data Acquisition starter kit with Windaq software. Features four differential analog input channels, 12-bit measurement resolution, and a full scale range of ±10V.
Suitable for measuring preamplified analog signals, the DI-1100 with included WinDaq software allows real time data acquisition, playback, and analysis performance equal to or better than other products that cost many times its low price. Predecessors of this instrument have been sold to over 35,000 hobbyists and professionals for countless data acquisition applications around the world. The DI-1100 continues this legacy with a higher resolution and faster ADC than its predecessor while retaining its noise-cancelling differential analog inputs that are level-protected to ±100 VDC or peak AC. This is our fastest, most flexible, and value-oriented starter kit ever. The DI-1100 offers four analog input and two discrete (digital) input channels. The analog inputs offer a fixed measurement range of ±10VFS, and are multiplexed to an integrated 12-bit ADC. Digital inputs are protected to ±30 V dc. Sample rates as slow as 20 Hz and as fast as 40 kHz with a single enabled channel are supported.
