The National Instruments PXI-2501 is a versatile PXI Multiplexer Switch Module designed for high-speed inspection of low-voltage (LV) signals. This module supports 1-, 2-, or 4-wire configurations with a total of 48 channels, making it adaptable for various applications including matrix and multiplexer switching, facilitated by different terminal block accessories. Utilizing FET switches, the PXI-2501 features short settling times and achieves a maximum scan rate of 15,000 channels per second. It is equipped with a comprehensive scan list capable of handling up to 1,024 steps for deterministic scanning, ensuring precise control in complex test environments.

Connectivity is managed through a 68-pin male SCSI connector, while the module has robust trigger characteristics, accommodating 70 ns PXI trigger lines and 500 ns front panel trigger lines, with output triggers available through PXI and front panel options at a pulse width of 1 μs. By default, the PXI-2501 operates in two-wire configuration mode, where channel pairs are switched together within corresponding banks. It also possesses a four-wire mode, ideal for resistance measurements, and can be configured as a 2-wire, 6 by 4 crosspoint matrix when paired with the TB-2606 terminal block. The module measures 21.6 cm x 2.0 cm x 13.0 cm and weighs approximately 173 grams.
