A Small Footprint Computer Delivers High Resolution Data Acquisition
Mosaic's new product, the QCard, packs a C-programmable computer, a 16 MHz 68HC11F1 Motorola microprocessor, up to 1 MB of memory, communications, analog and digital I/O, and an expansion I/O bus onto a tiny, low-cost board. An optional real-time clock tracks the calendar and time of day and battery backs the 128K RAM. The QCard is easily programmable in C, Forth or Assembly using any PC. On-board I/O includes 8 digital I/O lines with counter/timer capabilities, 8 analog inputs, a fast synchronous SPI serial interface, and dual RS232/485 ports. In addition, the I/O-rich QCard can host up to four stackable I/O modules called Wildcards, that can be mixed and matched depending on the application.
For those applications that require high resolution measurements, add Mosaic's 24/7 Data Acquisition Wildcard to create a custom off-the-shelf DA system. Mounted on the QCard, it is the instrument's complete analog front end, offering exceptional resolution, stability, and noise rejection. The 24/7 DA Wildcard accepts low level signals directly from transducers - it amplifies and conditions them - and it converts them with 24 bits of resolution with no missing codes performance. This analog-to-digital subsystem performs all the signal conditioning and conversion for up to seven input channels. Amplifier gain, low-pass filter corner frequency, and sampling rate are all software programmable using simple commands.
This data acquisition system can extract highly accurate data, even from noisy sources with imperfect signal conditioning in electrically harsh environments. It has 256 times the resolution of standard 16-bit converters, but at comparable cost.
The QCard is $119 and the DA24/7 Wildcard is $112 in 100s.
