The Marvin Test Systems/Geotest GX7310 is a 20-slot, 3U PXI chassis engineered to host a PXI controller and up to 19 PXI or CompactPCI (cPCI) 3U instruments. It operates as a slave chassis within the GX7300 series and supports both embedded and remote controllers via interfaces such as the GX7990 or MXI-4. The compact 3U form factor delivers flexible, scalable test architecture for demanding measurement environments.
Technical Specifications
• Slot Configuration: One system controller slot (Slot 1), one trigger-capable or instrument slot (Slot 2), 13 trigger-capable instrument slots (Slots 3–15), and five instrument-only slots (Slots 16–20).
• Power Supply: 755 W system power supply; 800 W and 1100 W configurations available.
• Cooling: Four 65 CFM forced-air fans mounted at the card cage base; dedicated fan cools system power supply.
• Smart Chassis Functions: Per-slot temperature monitoring, system power supply monitoring, PXI trigger mapping, and automatic shutdown on over-temperature detection via onboard microcontroller.
• PXI Backplane: Full PXI and CompactPCI 3U module support.
– Key Features
• Accommodates embedded CPU or PXI bus expander interfaces for flexible controller deployment.
• Integral per-slot thermal monitoring prevents component damage and ensures system reliability.
• Supports both PXI Star Trigger and non-trigger modules across designated slots.
• Mass interconnect configurations available for high-density I/O requirements.
• GxChassis software provided, including driver libraries, programming examples, and virtual panel application for chassis control and configuration.
– Typical Applications
• Multi-instrument test racks requiring centralized PXI control and distributed measurements.
• Space-constrained environments benefiting from 3U chassis density.
• Systems leveraging remote controllers over MXI-4 or equivalent expansion interfaces.
• Thermal-sensitive applications requiring real-time temperature monitoring and fault protection.
– Compatibility & Integration
The GX7310 integrates with standard 3U PXI and CompactPCI modules. Remote controller architectures utilize GX7990 interfaces or MXI-4 protocols. Software drivers and virtual panel tools enable straightforward integration into larger automated test environments.
