Noise eXtended Technologies (Noise XT) introduced the NXA Series, a new family of phase noise analyzers. Noise XT exhibited the new product line for the first time at IMS 2012. 

The NXA Series 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. The NXA Series offers the industry's lowest residual noise performance by using dual channel architecture to cancel its internal noise floor. 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).

"We've designed the NXA Series for ease of use," said Guillaume de Giovanni, President, Noise XT. "With a single connector input and a touch screen interface, any engineer or technician can operate the NXA quite easily. You simply inject the signal into the input port, type in the frequency, and press 'Measure'. The new small size makes no compromise for performance. We've retained all of the very low phase noise characteristics that customers expect in our products."

Noise XT products are used throughout the world for high-performance phase noise and jitter-sensitive applications such as ultra-low noise OCXO, surface acoustic wave oscillators (SAW), and optical-electrical-optical (OEO) microwave oscillators; RF and microwave amplifiers; pulsed microwave for radar; low-noise synthesizer design; and other demanding noise applications.

NXA Series features industry's lowest noise floor

The NXA Series measures absolute phase noise and residual phase noise. Options are available for amplitude noise and measurement of phase and amplitude noise on pulsed signals. Combined with very close-to-the-carrier analysis, the NXA is the most complete noise analyzer on the market today.

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.
