UXA analyser delivers best phase noise to capture elusive signals

Keysight Technologies, the test and measurement spinoff from Agilent, has launched a new flagship signal analyser in its X-Series range, writes Nick Flaherty.

The N9040B UXA combines industry-leading phase noise performance as well as 510MHz analysis and real-time bandwidths with a large display and touch-driven interface for the development of radar, electronic-warfare and communication systems.

Keysight's proprietary local-oscillator (LO) technology achieves phase noise of -136 dBc/Hz at 1 GHz, 10 kHz offset, and -132 dBc/Hz at 10 GHz, 100 kHz offset. The maximum analysis bandwidth of 510 MHz can be used across the full frequency range with excellent spurious-free dynamic range (SFDR) of >75 dBc. This enables accurate characterisation of parameters such as wideband chirp linearity.

When monitoring or capturing highly elusive signals, the optional 510MHz real-time spectrum analysis capability provides 100% probability of intercept (POI) for durations as short as 3.84µs.

"Built on our unique technology, the UXA delivers clarity in signal analysis," said Andy Botka, vice president and general manager of Keysight's Microwave and Communications Division. "The quality of its IF section enables a designer to understand what's happening inside their system and helps them prove that it's meeting or exceeding its performance goals."

The 14.1-inch screen UXA allows the user to view results using an array of flexible measurement displays. Based on the familiar Agilent X-Series menu structure, the touch-driven interface supports gestures and simplifies measurement and analysis with most setup items taking two taps.

For detailed signal analysis, the UXA supports the Keysight 89600 VSA software. With support for more than 75 standards and formats, the 89600 VSA makes it possible to see through the complexity of challenging signals in radar, EW and communication applications including 5G.

In secure environments, features such as a removable solid-state drive ensure compliance with the most stringent requirements.

Keysight is expected to be fully independent of Agilent in early November.
