Phase noise analyzers offer the industry's lowest residual noise

Noise eXtended Technologies (Noise XT) has launched the NXA Series, a family of phase noise analyzers that simplifies phase noise testing by incorporating a completely new one-box system design.

With a category-leading 14-inch touch screen and a redesigned user interface, phase noise measurement is now faster and easier. By using dual channel architecture to cancel its internal noise floor, the NXA Series offers the industry's lowest residual noise performance claims the manufacturer. The NXA Series is available in three models: NXA-6 (up to 6 GHz), NXA-26 (up to 26 GHz), and NXA-50 (up to 50 GHz).

Users simply inject the signal into the input port, type in the frequency, and press 'Measure'. Options are available for amplitude noise and measurement of phase and amplitude noise on pulsed signals. The NXA is designed with a two-channel phase and amplitude noise analyzer using cross-correlation to cancel its own internal noise. The resulting tests are similar to comparing the output of two separate systems, while displaying only the similarities and rejecting the differences. The residual noise measurement mode includes all the necessary functions to automatically measure noise on 2-port devices with an external phase shifter, either in RF or microwave frequencies. An additional feature is the ability to eliminate most FFT noise, allowing much better precision compared to the 7-8 dB trace thickness that is typical in competitive products.
