asynchronous "telegraphing" ADC channels are available for monitoring slow changing
parameters.
The eight analog input channels are separated into two banks of four. Each bank is
multiplexed into one 16-bit 200kHz A/D converter.
Both A/D converters sample
simultaneously and synchronously at the maximum conversion rate resulting in a total
throughput of 400kHz. This unique arrangement allows pairs of channels to be digitized
without phase-shift. If the bandwidth of the experiment calls for lower sampling rates, the
DSP decimates and/or filters the data. An added benefit of filtering is the reduction of
noise.
The PCI-1600 Bus mastering host interface card supports one or two I-1600 rack units. If
two rack units are used, then all input and output channels are doubled and fully
synchronized. For systems requiring even more channels, multiple PCI-1600 and I-1600
units are used. Multiple PCI-1600 cards installed in the same or in separate computers can
be synchronized.
