Marvin GX7990 PXI Bus Expander
The Marvin GX7990 PXI Bus Expander permits coordinated control of a GX7x1x PXI Chassis from a PC or from another PXI Chassis. The GX7990 gives a straightforward programming interface to the PXI transport utilizing PCI connect innovation. The GX7990 can be ordered as part of a kit, which contains a host interface card and a PXI backplane controller or it can be purchased separately. The GX7990 offers throughput of 132 MB/s maximum. This permits memory serious PXI items, such as the GX5xxx group of computerized I/O cards, which utilize burst exchanges performed at full transport rates, to stay unaffected by the additional PCI connect. Standard information exchanges utilizing the GX7990 acquire a 270 ns delay. Other PXI items, for example, flag exchanging cards that do not utilize burst exchange are unaffected by the inactivity.
The GX7990 PXI Bus Expander supports 32-bit and 64-bit configurations and can be used with a 4 foot cable to link the slave to the host. This 3U/6U PXI Instrument can be utilized for PCI to PXI or PXI to PXI applications.
The signal is dispersed to each opening utilizing approach length follows and a low jitter clock driver. This regular reference clock can be utilized for synchronization of various instruments in estimation or control framework. The star trigger controller in space two can supply an outer 10 MHz reference clock. When the GX7990 identifies the nearness of an outer reference clock, it naturally changes from the interior reference source to the outside source.
