XB103 Acqiris ASBus Dual Termination Bridge

The Acqiris DC211, DC241, DC271 cPCI High-Speed Digitizers with single, dual and quad channels respectively, set a new performance standard in single width 6U CompactPCI modules. The DC271 has four channels that can synchronously sample signals at 1 GS/s rates. The DC241 has two channels each with up to 2 GS/s sampling. Both modules use channel interleaving to achieve the same blistering 4 GS/s single channel performance of the DC211. All the modules combine this ultrafast sampling rate with 1 GHz wide bandwidth and 512 kpoints of storage memory (optional to 32 Mpoints). Measuring just 233 mm by 160 mm in size the digitizers smash all previous speed, density and power consumption performance levels.

The DC211, DC241 and DC271 are the ideal instruments for characterizing very fast signals. With over 1 GHz bandwidth and 4 GS/s sampling rate the digitizers allow precise measurements (jitter, risetime, falltime, overshoot, etc.) with sub-nanosecond accuracy and resolution. Waveforms are stored directly into the digitizer's large acquisition memories so that complex signals can be stored over very long periods of time. Large memories are essential for maintaining fast sampling rates and, therefore, timing resolution. For example, a Model DC211 with 32 Mpoints of memory can record a signal over an 8 ms period with a sampling rate of 4 GS/s (250 ps per point). The fast sampling rate ensures that all high frequency signal components, up to the full 1 GHz bandwidth of the digitizer, are accurately recorded.
