The LIH 1600 is a high resolution, low-noise scientific data acquisition system. It utilises the newest fiber optic and digital signal processing technologies, in addition to many of the exceptional features of its predecessors the ITC-16 and ITC-18. The LIH 1600 provides expandability and versatility that will satisfy both current and future needs.

The LIH 1600 system comprises of a PCI computer interface card and one or two analog rack units connected by the fiber optic data cables. The fiber optics provide superb optical isolation, virtually eliminating ground loops, while increasing the distance between the computer and the recording set-up to at least five meters. Fiber optic cables are small, flexible, and, unlike conventional electrical cables do not emit electromagnetic radiation.

The LIH 1600 rack unit has eight analog inputs, four analog outputs, sixteen digital inputs and sixteen digital output channels all sampling synchronously. In addition, two 12-bit 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 200 kHz A/D converter. Both A/D converters sample simultaneously and synchronously at the maximum conversion rate resulting in a total throughput of 400 kHz. 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 (digital signal processor) decimates and/or filters the data. An added benefit of filtering is the reduction of noise.

The PCI Bus mastering host interface card supports one or two LIH 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 LIH 1600 units are used. Multiple PCI cards installed in the same or in separate computers can be synchronised.

The LIH 1600 interface can be controlled from PATCHMASTER, PULSE, or TIDA. IgorPro XOPs which allow to stimulate and to acquire data directly from IgorPro are also available (Windows only) and can be downloaded from our download page.

Please note: PCI-1600 boards for the PCI-X bus and for the the PCIe (PCI Express) bus standard are available (please specify your PCI bus type upon ordering).
