4. Product Introduction (Anti-Template)
The National Instruments SCXI-1193 is a high-density 50 Ω RF multiplexer switch module for the SCXI platform. It is designed to route RF signals up to 500 MHz while maintaining signal integrity in automated test and measurement systems.
The module can be software-configured into several multiplexer topologies, including quad 8×1, dual 16×1, and a single 32×1 unterminated multiplexer. With external 50 Ω terminators on selected channels, it can also operate as terminated multiplexers (quad 4×1, dual 8×1, or single 16×1). Additional flexible configurations, such as multiple independent 3×1 multiplexers, are supported. The SCXI-1193 does not route signals to the SCXI high-voltage analog bus. It is controlled through the NI-SWITCH driver and is used in applications requiring high-channel-count RF signal routing within an SCXI chassis. As part of the legacy SCXI platform, the module is sourced primarily from surplus and specialist channels.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model number (SCXI-1193), connector condition (MCX or equivalent RF connectors), and physical integrity. Photograph all labels.
- Functional Testing – Install in a compatible SCXI chassis, load NI-SWITCH, and verify relay operation and basic path continuity. Full RF performance validation requires appropriate test equipment.
- QA & Packaging – Protect RF connectors and the module edges, clean according to electronics handling practices, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial switch / multiplexer modules. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Topology Configuration – Select the correct topology in software (MAX or NI-SWITCH). Incorrect topology settings will produce unexpected routing behavior.
Termination – For terminated multiplexer modes, install proper external 50 Ω terminators on the designated channels. Missing terminators degrade RF performance.
SCXI Chassis Compatibility – Confirm the host SCXI chassis and controller support the module and the required power rails.
Legacy Platform – SCXI is a discontinued platform. Ensure compatible drivers and operating system support are available before deployment.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified SCXI-1193?
As a legacy SCXI RF switch module, availability depends on surplus stock. Typical lead time after verification is 5–15 business days plus standard shipping.
What is the primary function of this module?
It is a high-density 50 Ω RF multiplexer designed to route signals up to 500 MHz in an SCXI system.
What multiplexer configurations does it support?
Quad 8×1, dual 16×1, single 32×1, and corresponding terminated versions, plus independent and 3×1 configurations.
Does it support the SCXI high-voltage analog bus?
No. The SCXI-1193 does not route signals to the high-voltage analog bus.
What driver is required?
NI-SWITCH.
Is the module still in production?
No. SCXI is a discontinued National Instruments platform. Units are sourced exclusively from surplus and specialist refurbishment channels.
What should be confirmed before ordering a replacement?
Exact model (), required topology, availability of compatible SCXI chassis and NI-SWITCH driver support, and RF connector/cabling requirements.
