Overview
The NI PXI-2596 is a dual 6x1 multiplexer switch module for routing RF or microwave signals in automated test applications. While designed to operate with less than 1 dB insertion loss up to 26.5 GHz, the PXI-2596 appears almost invisible to signals at much lower frequencies as well. It offers a high-density, unterminated multiplexer option with dual 6x1 multiplexer banks in the same module. The PXI-2596 also is well-suited for passing high-order harmonics from RF upconverters such as the NI PXIe-5673 6.6 GHz RF vector signal generator or routing multiple sources to RF downconverters such as the NI PXIe-5663 6.6 GHz RF vector signal analyzer.
- 26.5 GHz performance (typical): -0.3 dB insertion loss; VSWR of 1.25
- 6.6 GHz performance (typical): -0.15 dB insertion loss; VSWR of 1.13
- 50 Ω characteristic impedance
- Onboard relay count tracking
- Ability to store RF path calibration information with NI Switch Executive
