Keysight’s Vector Signal Generator intended for dense wideband multichannel applications

1 min read

Keysight Technologies has introduced a compact, four-channel vector signal generator (VSG) that’s capable of signal generation up to 8.5 GHz with 960 MHz of modulation bandwidth per channel.

The N5186A MXG is the next-generation high-performance VSG in Keysight’s X-Series signal generator portfolio, offering the multiple, individually complex signals needed for dense wideband multichannel applications.

Evolving technologies in wireless communications and radar applications are demanding higher frequency coverage using complex modulation schemes like MIMO, beamforming, and multiplexing to maximise data throughput.

However, testing these applications requires signal generation instruments that maintain excellent modulation quality when working with greater bandwidths. So, too achieve higher frequencies, greater bandwidths, and more complex modulation schemes, network and design engineers typically need more bench space for additional test equipment and fixtures.

The Keysight N5186A MXG has simplified complex setups with reduced external connections and up to four channels in a compact 2U form factor. The world’s first signal generator to feature an embedded reflectometer, the N5186A MXG delivers extremely accurate signals to the device under test (DUT).

The N5186A MXG offers the following benefits:

Compact design – Delivers multichannel capabilities in a 2U size that saves up to 75% of rack height.

High-performance capabilities – Employs direct digital synthesis (DDS) digital-to-analogue converter (DAC) proprietary technology for bandwidth coverage up to 960 MHz with best-in-class error vector magnitude (EVM) and adjacent channel power ratio (ACPR) performance for lower signal distortion.

Testing convenience – Features an embedded reflectometer delivering accurate signals while enabling faster time-to-test and simplifying test setups.

Exceptionally low phase noise – Produces pure signals enabling high resolution radar system designs and high-throughput, next-generation communications systems.

By providing consistent and repeatable results, the N5186A MXG vector signal generator is suitable for a broad range of commercial and aerospace defence applications.

Its custom DAC application-specific integrated circuits (ASICs) use DDS to deliver precise signals to minimise distortion and meet the evolving standards for component and module design. In addition, the embedded reflectometer expedites the setup process to correct for the match of the DUT, enabling a faster time-to-test.

Joe Rickert, Vice President and General Manager, Keysight High Frequency Measurements Centre of Excellence, said, “The ground-breaking N5186A MXG vector signal generator is a leap forward in terms of the performance and simplicity it offers design and network engineers. As the world’s first signal generator with an embedded reflectometer, the high-performance MXG delivers powerful, precise signals.”
