Profile: Geotest-Marvin Test Systems, Inc. produces electronic test products. We are an ISO 9001:2000 certified company. Our product line includes chassis & controllers, bus interfaces, power supplies & systems and other speciality products. Our GX7600 series mainframes are compact, 9-slot PXI chassis that can accommodate up to 8 instruments as well as an embedded single slot PXI Express controller such as the GX7940 or a PXI Express external bus controller such as the x1 or x4 MXI - PXI Express interface. The GX7600's compact 3U form-factor occupies only 9x18 inches of bench space, making it ideal for benchtop or space constrained applications. And when combined with 8 peripheral slots, integral Smart functions, and the bandwidth of PXI Express, the GX7600 represents a new level of performance, capabilities and value for PXI mainframes. System power for the GX7600 series is provided by a single power supply configuration that provides 550 watts of system power. The nine-slot layout of the GX7600 consists of five PXI slots, two PXI hybrid slots, one PXIe timing slot, and one cPCIe controller slot. The PXI backplane supports a x4 PCI Express lane configuration for the two hybrid slots and the system timing slot, providing an aggregate bus bandwidth of 3 GB/s. Our MXIe PXI-Express bus expanders allows a direct control of PXI-express systems from any PCI express slot in a desktop computer or server. MXIe-Express configurations are available for supporting both the x1 and x4 PCI-Express lane configurations. Either lane configuration can remotely control one or two PXIExpress chassis. The MXIe-Express technology utilizes a highbandwidth link that is transparent to software applications and drivers, providing the ability to use desktop computers or servers to control PXI-Express systems.
