The Pickering 40-725-511 is an 8×9 RF coaxial matrix switch module for signal routing in automated test and measurement systems. This single-slot 3U PXI card delivers high signal integrity across frequencies to 500 MHz, with sputtered ruthenium reed relays rated for 10^9 operations and automatic isolation switches on all connectors. Available in 50 Ω and 75 Ω impedance versions with multiple connector options, it integrates directly into PXI and LXI chassis via 32-bit P1/J1 backplane interface.

– Key Features
• Automatic isolation switches disconnect the matrix from external test fixtures when inactive, maximizing RF performance and isolation
• Low insertion loss and high signal integrity across the operating band
• VISA and IVI (pi40iv) driver support for straightforward software integration
• PXI Specification 2.1 compliance ensures standardized backplane compatibility
• Segmented matrix design on both axes provides flexibility in signal routing architecture
– Typical Applications
• RF and microwave signal routing in automated test equipment (ATE)
• Communication system characterization and validation
• Multi-channel RF signal switching in laboratory and production environments
• Frequency-selective component testing requiring high isolation between paths
– Compatibility & Integration
The module operates within PXI and LXI chassis ecosystems. Driver support includes VISA and IVI frameworks; compatible development environments span LabVIEW, LabWindows/CVI, Microsoft Visual Basic, and Microsoft Visual C++. Coaxial connector options—including 50 Ω SMB, 75 Ω SMZ/Type 43, 75 Ω 1.0/2.3, and 75 Ω Mini SMB—accommodate diverse impedance requirements and physical interface constraints.
