Keysight Technologies E4440A

The Keysight E4440A PSA high-performance spectrum analyzer measures and monitors complex RF and microwave signals up to 26.5 GHz. With optional external mixing, the frequency coverage expands to 110 GHz by Keysight's external mixer, and to 325 GHz by other vendors' mixers. Migration from PSA to PXA or UXA:

The PXA N9030A, Keysight's next-generation high-performance signal analyzer, combines the PSA’s technical excellence with state-of-the-art technologies, making it a logical form-fit-functional replacement for the PSA. The PXA N9030A, N9030B or UXA N9040B all offer greater performance, wider analysis bandwidth, and more powerful connectivity.
