National Instruments SCXI-1194 RF Multiplexer Switch Module

The SCXI-1194 (Part Number: 776572-94) is a Quad 4x1 high-frequency unterminated Multiplexer Switch Module. The NI SCXI-1194 plays out an indistinguishable capacity from the PXI-2594, but in a higher density, quad 4x1 multiplexing setup. The SCXI-1194 is equipped for changing signals from DC to 2.5 GHz. The main impedance of the channels on this module is 50 Ω. This module offers SMA direct connectivity, excellent insertion loss, VSWR and isolation specifications, onboard relay counting, and one slot.

The NI SCXI-1194 has a maximum voltage rating of 30 Vrms with a maximum exchanging current of 500 mA. This feature ensures the module is appropriate for applications that require the directing of high-frequency signals inside computerized test gear frameworks, since they can switch signals with low insertion loss. Additionally, the superb voltage standing-wave ration (VSWR) and isolation parameters make this module the ideal choice in any framework that is fit for high-frequency applications.

This Multiplexer Switch Module counts relay closures on all the RF relays; relay counts are incremented every time a relay is actuated. The counts are saved on the module and can be retrieved through programming. The counts can be utilized for predictive maintenance to diminish unanticipated system downtime.

The NI SCXI-1194 comes with NI-SWITCH, which is an IVI-compliant driver providing full functionality for the switch module. For extra help with arranging, programming, and managing higher-channel-count switching systems, NI Switch Executive software provides a simple-to-utilize, clever switch management and visual directing environment. In addition, the NI-SWITCH Soft Front Panel can be utilized for easy relay functions or debugging switch code/execution.

The NI device weighs 1 oz (2 lb), and measures 1.2 x 6.8 x 7.8 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 50 °C, a storage temperature range of –20 °C to 70 °C, and a non-condensing relative humidity range of 5% to 85%. The module is designed to comply with the following electrical safety standards: IEC 61010-1, EN 61010-1, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1.

SCXI-1194 Obsolete Status has been declared by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
