The National Instruments part number 778572-47 refers to the PXI-2547 PXI RF Multiplexer Switch Module, engineered for precise signal routing in automated testing environments. This module operates over a frequency range from DC to 26.5 GHz, characterized by a maximum switching voltage of 30 V and a maximum current of 0.5 A per channel, with a capacity to handle up to 10 Watts of RF power. Insertion loss is optimized to less than 1.05 dB up to 1 GHz and less than 2.0 dB up to 2.7 GHz. The module maintains a Voltage Standing Wave Ratio (VSWR) below 1.4 at 1 GHz, and below 1.6 at 2.7 GHz, enhancing impedance matching and minimizing signal disruptions. Trigger functionalities are supported through PXI trigger lines <0...7>, with input trigger capabilities featuring a minimum pulse width of 150 ns, and output triggering ranging from 1 µs to 62 µs. The PXI-2547 is engineered for durability, offering a mechanical life rating of 1 × 10^6 cycles and an electrical life of 3 × 10^5 cycles at maximum load. Enclosed in a 3U, single-slot PXI/cPCI form factor, this module measures 21.6 cm x 2.0 cm x 13.0 cm (8.5 in. x 0.8 in. x 5.1 in.) and weighs 255 g. It is designed to withstand operational shocks of up to 30 g peak and random vibrations from 5 Hz to 500 Hz at 0.31 grms. The operating temperature range is from 0 °C to 55 °C, while the storage conditions allow for temperatures from -40 °C to 70 °C. The module supports humidity levels from 10% to 90% non-condensing during operation, and 5% to 95% non-condensing during storage, complying with IEC 60068-2 standards. It is suitable for installation at altitudes up to 2,000 meters and adheres to Pollution Degree 2 standards.
