Test & Measurement: 12-Bit CompactPCI Digitizer Cards Sample Up To 200 Msamples/s

The 100-MHz DC438 and 50-MHz DC436 12-bit compact two-channel CompactPCI digitizer cards sample at 200 and 100 Msamples/s, respectively. These devices feature a signal-to-noise ratio up to 62 dB, a spurious-free dynamic range of more than 75 dB, total harmonic distortion of less than −73 dB, and an effective number of bits of more than 10. Rise and fall times are 3.5 and 7 ns, respectively. Full bandwidth is available on all gain ranges from 250 mV to 10 V full scale. Both cards feature 32 kpoints/channel of memory, optionally expandable to 2 Mpoints/channel. They cost $10,990 and $8490 each, respectively.
