Description
The PXI-2501 is a high-performance NI 2501, featuring a 24-Channel Low Voltage FET MUX. This device is designed to cater to a variety of testing needs, thanks to its versatile configuration options which include 1-, 2-, 4-Wire setups, and can be configured as either a matrix or a multiplexer switch, depending on the application requirements.
It boasts a significant 48-Channel capacity, making it suitable for applications that require multiple channel testing simultaneously. The switch type utilized in this device is FET based, known for its fast switching times and low thermal offset, which makes it ideal for precise, low-voltage measurements. The PXI-2501 can achieve a remarkable maximum scan rate of 15,000 channels/s, enhancing testing efficiency and throughput.
The device features a 68-pin male SCSI connector type, ensuring easy integration and reliable connection to other equipment. With dimensions of 21.6 x 2.0 x 13.0 cm and a weight of 6.1 oz, it is both compact and lightweight, making it an excellent choice for setups where space is at a premium.
Triggering capabilities are robust, with PXI trigger lines operating at 70 ns and front panel trigger lines at 500 ns. This feature allows for seamless synchronization with other PXI modules. Additionally, the output trigger capability supports <0…7> PXI trigger lines, with front panel output at 1 μs pulse width, offering flexibility in signal routing and synchronization.
The device is set by default in a Two-wire configuration mode, making it ready for a wide range of testing scenarios right out of the box. The part numbers associated with this model are 185101H-01L, 777696-01, and 185101G-01L
