Keysight updates signal analysers with 1GHz analysis b/w

February 04, 2016 // By Graham Prophet
Keysight Technologies’ X-Series signal analysers now feature a multi-touch user interface (UI) that streamlines measurement setup; performance improvements and feature enhancements address emerging needs in aerospace, defence and wireless communications.

The multi-touch interface enables, Keysight says, optimisation of measurement parameters in one or two touches; the instruments offer integrated 1 GHz analysis bandwidth to simplify test setup for analysis of wideband systems in radar and 5G research; real-time streaming up to 255 MHz bandwidth enhances analysis of intermittent and highly elusive signals; and best-available phase noise performance in all models addresses emerging needs in radar, and LTE.

Support for gesture-driven controls, such as pinching, dragging and swiping, makes analysis more immediate and intuitive; operation has been made consistent across the UXA, PXA, MXA, EXA and CXA models. The flagship UXA now offers frequency coverage to 44 or 50 GHz and integrated 1 GHz analysis bandwidth, claimed as an industry first. The PXA now offers benchmark phase noise performance of -136 dBc/Hz at 1 GHz, 10 kHz offset, and real-time bandwidth of 510 MHz with spurious-free dynamic range greater than 75 dBc over the full span.

To characterise signal interactions in dense radar environments, the UXA and PXA support real-time data streaming at up to 255 MHz bandwidth with 16-bit resolution at 300 Msamples/sec. When coupled with a data recorder from solution-partner X-COM Systems, the analysers support real-time acquisition with up to 15 TB (> 3 hrs) of capture memory.

X-Series applications with multi-touch simplify complex operations with ready-to-use measurements for pulse analysis, analogue demodulation, noise figure, phase noise, LTE/LTE-Advanced and W-CDMA. The new pulse application accelerates the development and verification of chirped wideband signals, such as those used in advanced radars. Updates to the LTE/LTE-A application simplify characterisation of systems that use carrier aggregation by supporting 256QAM and providing visible configuration of all component carriers.

The N897xB NFA X-Series noise figure analysers include a larger display, multi-touch UI, and improved performance compared to their predecessors. These capabilities enhance a user's ability to make fast, accurate and repeatable noise-figure measurements up to 40 GHz with a dedicated solution.
