The Keysight E1470A is a C-size, 1-slot VXI register-based module engineered for high-density RF signal routing in automated test systems. It delivers twenty independent 3:1 multiplexer configurations that cascade to form larger architectures—up to 60:1 single multiplexers or multiple simultaneous combinations including 6:1 and 9:1 configurations. This cascading flexibility enables efficient multi-signal management across complex test benches.

– Key Features
• Twenty cascadable 3:1 multiplexer elements for flexible RF routing topology
• High isolation across 500 MHz bandwidth ensures signal integrity in multi-channel switching applications
• Register and SCPI command control for integration into existing automated test frameworks
• SMB connectors on front panel for direct probe and cable connectivity
• Included E1470-80003 kit: ten cable housing assemblies and 80 cable jacks with Keysight-specific male connectors (P/N E1470-22101) for full socket utilization
– Typical Applications
RF multiplexing in production test environments; multi-channel signal distribution in matrix switching arrays; automated measurement systems requiring configurable routing; applications where cascaded multiplexer topologies reduce system footprint while maintaining 50 Ohm impedance.
– Compatibility & Integration
VXI C-size, 1-slot module. Programmable via SCPI commands or direct register read/writes. Operates as slave-only, A16 addressable device within standard VXI systems. Standard SMB connectors may restrict adjacent slot usage due to connector diameter; supplied E1470-22101 jacks recommended for optimal spacing.
