National Instruments 780587-43 Multiplexer Switch Module 

National Instruments part number 780587-43 is an identifying part number for the PXIe-2543, a PXI RF Multiplexer Switch Module with 2 Banks, 4 Channels and a switch bandwidth of 6.6 GHz. This RF Multiplexer Switch Module has a low switch operating time of 76 microseconds, measured from TRIG IN falling to 10% to 90% of the final value at the output. Its input trigger pulse width is 150 nanoseconds, and it can recognize trigger pulse widths shorter than this when digital filters are disabled. The NI 780587-43 features built-in FET relays that allow for fast switching and quick measurements. These durable relays perform well in tough industrial environments. The device has a minimum input frequency of 10 MHz, a characteristic impedance of 50 Ω, and a maximum safe DC input voltage of ±8V. 

It has several front panel connectors, including 10 female SMA jacks for input/output and 2 female SMB jacks for trigger mechanisms. The module requires 0.4 W at 12 Volts and 1 W at 3.3 Volts. The front panel of the NI 780587-43 RF Multiplexer Switch Module includes 10 female SMA jacks for input and output connections, along with 2 female SMB jacks designated for triggers. The module is designed to switch signals quickly, with a maximum switch operating time of 76 microseconds. It supports high-power RF applications, capable of handling up to +30 dBm of continuous RF power with the chassis powered on, and up to +20 dBm with the chassis powered off. It has a pollution degree of 2 and is operated using the NI-SWITCH driver software. 

This software is compatible with various application development environments (ADEs) such as LabVIEW, LabWindows/CVI, and Measurement Studio. This NI device weighs 27.3 ounces and has physical dimensions of 8.5 by 0.8 by 5.1 inches. It operates best within a temperature range of 0°C to 55°C and can be safely stored in temperatures ranging from -20°C to 70°C. The device operates in environments with humidity levels ranging from 5% to 85%, without condensation.
