Agilent Technologies has announced that their PXA signal analyzer is now operational to 50 GHz, and can cover frequencies to 325 GHz and higher with external mixing. Suitable for testing signals in radar, surveillance, and wireless communications systems, the PXA analyzers employ advanced technologies such as low-noise-path and Noise Floor Extension (NFE) techniques for wide-dynamic-range performance with high sensitivity. The displayed average noise level (DANL) is -138 dBm at 50 GHz. The phase noise is -110 dBc/Hz offset 10 kHz from a 50-GHz carrier with a third-order intercept of +13 dBm at 50 GHz.

According to Guy Sene, Vice-President and General Manager of Agilent's Microwave and Communications Division, "As frequencies move into the millimeter range, the ability to make good spectrum and other signal measurements gets significantly tougher. As the industry's highest performance millimeter-wave signal analyzer, the PXA is able to simplify these measurements, while ensuring our customers still get the accurate results they demand."
