Description
The National Instruments PXIe-2540 PXI Matrix Switch Module, with part number 780587-40, operates up to a frequency range of 350 MHz and is configured as an 8 x 9 matrix.
Typical contact resistance is below 2.1 ohms, increasing to above 3.1 ohms towards the end of the relay’s life cycle. This module can handle a switching power of up to 10 Watts and a switching voltage of 60 VDC, with a maximum current capacity of 0.5 amperes per channel.
RF power of the module decreases when the frequency increases or when there are more operational channels. Rapid relay operations are possible with the PXIe-2540, capable of completing up to 40 operations in just 0.25 microseconds. The front panel boasts 17 MCX jack connectors, allowing for versatile connection options.
It also includes 7 built-in input trigger lines with a pulse width of 150 nanoseconds and offers adjustable pulse widths for output trigger lines ranging from 1 to 62 microseconds. Despite the announcement of its obsolescence, the PXIe-2540 remains available for purchase and repairs through Apex Waves.
