National Instruments PXIe-2541 PXI RF Matrix Switch Module

The PXIe-2541 (Part Number: 780587-41) is a 300 MHz RF Matrix Switch Module from National Instruments with an 8x12 matrix topology. The NI PXIe-2541 RF Matrix Switch Module exhibits a maximum RMS value for AC switching voltage of 42.5 volts. The maximum value of DC switching voltage is 60 volts. The maximum switching or carry current is 0.5 amperes. This value is measured separately for each channel. This module has a special non-blocking design, which allows the user to carry out testing with maximum flexibility. The user can connect any row or matrix within the switching matrix simultaneously.

The PXIe 2541 module offers 50 ohm characteristic impedance. The value for insertion loss is less than 3 dB for Row In – Column configuration. It is less than 1 dB for Row In – Row Out mode of operation. These values are measured for a frequency less than or equal to 300 Megahertz. The module also has a feature for column expansion. The NI PXIe 2541 PXI RF Matrix Switch Module offers a simultaneous relay drive limit of 40 relays maximum. Their maximum operate and release time is 0.25 milliseconds.

The NI PXIe-2541 module incorporates built-in mechanical relays with a typical life duration of 1 x 10⁷ cycles. The module also incorporates 28 MCX jacks for different I/O connections. The accessories for the instrument include various types of connectors, as well as cables of varying lengths along with the connectors. The connector types are MCX-MCX, MCX-BNC, MCX-SMB, MCX-SMA, and 50 ohms MCX terminator. The NI PXIe-2541 RF Matrix Switch Module weighs around 410 grams.
