Rated 2.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by Our Quad08 experience We used the quad08 for two tasks. One involved standard encoder output and the other involved measuring rotation angle as a function of time. Both worked well. March 20, 2013
Rated 1 out of 5 by not for use with LabVIEW Let me just state for the record that my review is biased by my being a LabVIEW programmer. USB-QUAD08 held a lot of promise based on its specs but turned out to be very difficult to use in LabVIEW largely because it did not come with the same set of drivers that some of the other Measurement Computing devices have for LabVIEW use. To MC's credit one of their applications engineer did provide me with an labview example using invoke nodes utilizing .NET, a bit too advanced for my level. If you're not comfortable working with invoke node in Labview I would not recommend this product. March 19, 2013

Summary
The high-performance USB-QUAD08 data acquisition device provides simultaneous input and decoding for up to eight incremental quadrature encoders at resolution up to 48-bits. Its eight quadrature counters with indicator LEDs support both differential and single-ended inputs, and feature multiple programmable counting modes. The counters have less than 10 ns jitter, and accept input up to 10 MHz. The streaming speed to the PC is software configurable up to 8 MS/s. The USB-QUAD08 can also serve as a high-speed pulse counter for general counting applications. The eight digital I/O support up to 42.4 Vpk/50 VDC with clamping diodes for CEMF suppression.

The USB-QUAD08 has detachable screw terminals, and a 37-pin D-sub connector, pin-compatible with Measurement Computing’s PCI-QUAD04. A two-meter long USB cable is included with every USB-QUAD08 module. A one-meter long DB37F to 4 x DB9F (C37F-4X9F-1M) cable for connecting the device to four encoders via the 37-pin D-sub connectors is available as an option.
