[SatNews] Even more accurate millimeter-wave measurements are now available...

Agilent Technologies Inc. (NYSE: A) has announced that its PXA signal analyzer is now the industry’s highest performance millimeter-wave signal analyzer, covering frequencies up to 50 GHz. With external mixing, it can cover 325 GHz and beyond. The PXA offers the industry’s most accurate, sensitive and frequency-stable signal analysis. Its ability to measure small signals in the presence of very large signals is unparalleled and enables customers to develop the most advanced radar, surveillance and wireless communications systems. Extending this performance to 325 GHz and beyond allows customers to develop technology for advanced radio astronomy research and new imaging techniques. The robust hardware design of the PXA delivers outstanding sensitivity and wide dynamic range. To further enhance these inherent hardware capabilities, the PXA uses exclusive technologies like low noise path and Noise Floor Extension (NFE) to remove distortion noise and further widen dynamic range. This allows the PXA to measure the smallest of signals in the presence of very large signals, a task that has challenged test engineers and is critical to designing and testing leading-edge millimeter wave systems. As a result, the PXA allows customers to measure the most demanding devices and push their designs to unprecedented performance levels.

The lower noise offered in all measurement configurations, allows the PXA to achieve the same sensitivity as other analyzers at a resolution bandwidth that is 10 times greater, resulting in sweep times of 100 times faster or more. In many cases, this eliminates the need for the engineer to sacrifice test times for dynamic range. It also gives the engineer flexibility to trade off the PXA’s performance gains to optimize an ideal combination of measurement speed, accuracy and measurement confidence level. Using the low noise path, the PXA is able to realize a displayed average noise level (DANL) of -138 dBm at 50 GHz. In addition, using NFE, the PXA is able to further improve DANL by approximately 6 dBm. These performance characteristics, coupled with the PXA’s extended frequency range, the industry’s widest analysis bandwidth of 140 MHz, high-performance full-band preamplifier to 50 GHz, industry-best close-in phase noise of -110 dBc/Hz at 10 kHz offset, and third-order intercept of +13 dBm (nom) at 50 GHz, make it ideal for aerospace and defense engineers looking to extend operating frequency to millimeter wave. It can also be used by advanced research engineers operating in millimeter-wave frequencies in the commercial space.
