Get Closer to Your Answer with Accessible Performance

Measurement setup is simple with the X-Series' multi-touch user interface, customizable views, and one-button measurements. Not only are measurements easy, but you can capture signals you could not see before with a spurious-free dynamic range of > 75 dBc. You can also accurately measure low-level signals with noise floor extension (NFE) to reduce measurement noise by up to 10 dB.

Achieve easy, accurate, and detailed measurements with Keysight's X-Series signal analyzers.
