Description
The NI PXI-2590 is a Radio Frequency (RF) Switch that falls under the category of PXI Switches. It is identified by the part number 777987-01. This model is designed to accommodate a bandwidth of up to 1.3 GHz and is equipped with a 4-Channel Multiplexer. The characteristic impedance of this device is 50 Ω, making it suitable for a wide range of RF applications.
The PXI-2590 utilizes electromechanical, non-latching relays for switching, with an operating and release time of 15 ms typical. The contact material used in the switch is gold-clad silver, which ensures reliable performance over time. It is designed to withstand 5,000,000 mechanical cycles and 100,000 electrical cycles, highlighting its durability and longevity in demanding environments.
For maximum switching capabilities, the device can handle up to 24 V (channel-to-ground/channel-to-channel) and a maximum switching/carry current of 1 A. It also supports a maximum switching power of 24 Watts. At the start, the initial DC path resistance is <0.1 Ω, which may increase to >1 Ω towards the end of the device’s lifespan.
The PXI-2590 also features trigger signal input capabilities through PXI trigger lines 0-7 and STAR, with a minimum pulse width of 70 ns. Additionally, it provides a trigger signal output of 1 µs through PXI trigger lines 0 – 7. Connectivity options include 5 x SMB jacks, offering versatility in connecting to various types of RF sources and loads.
