16 ANALOG INPUTS/32 DIGITAL I/O SIMULTANEOUS SAMPLING
CPCI 1228
The CPCI 1228 board provides simultaneous and isochronous acquisition of 16 analog differential inputs, and 32 TTL I/O (2 x 16 bits). Each analog input possesses: − One instrumentation amplifier with softwareprogrammable gain (1 ; 2 ; 5 ; 10) (protection ± 40 V), − One 16-bit ADC, max speed: 250 kSamples/s, − One 128-sample programmable digital filter. CPCI 1228 takes advantage of the PXI concept for boardto-channel and rack-to-rack synchronization. Timesampling is performed through an IRIG B input followed by a synchronized oscillator which ensures a 1-μs resolution. CPCI 1228 features: − 2K-word measurement-descriptor table, ♦ 16 analog differential isochronous inputs ♦ 32 TTL I/O (2 x 16 bits) ♦ 16-bit ADCs 250 Ks/s per channel
− Dual-access RAM in FLIP-FLOP mode, 2 x 256 kwords, − 8 programmable interrupt sources with a debouncer. The board can be used as Master or Slave on the CPCI / PXI to ensure high transmission rates in real time environments.
♦ Software-programmable gains on each analog input ♦ 15 decimation ratios with anti-aliasing protection ♦ 1 programmable digital filter per channel
