Keysight N9040B UXA Signal Analyzer:Covers 2 Hz to 50 GHz, extendable to 110 GHz with Keysight smart mixers, and even to terahertz bands with third-party solutions.

The N9040B is a flagship-grade tool in the R&D lab for "dissecting" the most extremely complex signals. If your customer is involved in radar, electronic warfare, satellite communications, 5G/6G frontier R&D, or requires extremely in-depth transient and modulation analysis of Bluetooth/WLAN/RFID signals, this instrument is a matching choice; if it is only for routine production-line calibration or simple CW testing, its performance would be severely redundant.
