Keysight’s New Signal Analyzers Offer Excellent Phase Noise Performance

Post Series: Keysight News

Advance in wireless test with wider bandwidth and real-time analysis

In an RF Globalnet article, Keysight Technologies announced their launch of a new Series of Wideband Signal Analyzers that provide superior phase noise performance at higher frequencies with improved usability. These analyzers were developed to help improve design and manufacturing validation for engineers in wireless and satellite communication industries. The analyzers include software that improves workflows while meeting 3GPP 5G new radio (NR) compliance standards.

What’s New:

  • Improved phase noise with 3 Frequency Ranges: 10 Hz to 32/44/50 GHz
  • Extended analysis bandwidth including 255/510MHz
  • Improved usability with industry-leading software

The new Keysight N9021B MXA X-Series Signal Analyzer offers an enhanced frequency sweep algorithm, accelerating test time improvements with uncompromising performance. It provides radio frequency (RF) and millimeter-wave (mmWave) analysis to address the needs of engineers designing and delivering high-frequency new-generation wireless devices, including:

  • Advancing wireless and satellite communications design verification and manufacturing with the widest analysis bandwidth in its class and superior phase noise performance at high frequencies.
  • Eliminating the complexity of challenging signals by combining real-time spectrum analyzer (RTSA) with Keysight’s PathWave 89600 VSA software.
  • Capturing measurement expertise and delivering repeatable results with industry-proven PathWave X-Series Measurement Applications.
  • Maximizing the flexibility of test assets with a wide variety of PathWave X-Series Applications offering licensing terms that enable application sharing between X-Series signal analyzers and PXIe instruments.

Engineers need a test and measurement solution that addresses the signal analysis needs for a diverse set of wireless devices and systems, and provides the performance required to make rapid, accurate and repeatable measurements across both RF and mmWave frequencies. Keysight’s new MXA X-Series Signal Analyzer enables these engineers to overcome the challenges in identifying signals at higher frequencies and offers wider bandwidth to meet a breadth of wireless application test requirements.

The New N9021B MXA X-Series Signal Analyzer Offers the Following Key Features:

  • Frequency range of 10 Hz – 50 GHz meeting specification requirements for both 5G NR FR1 and FR2.
  • Signal detection with extended analysis bandwidth up to 510 MHz and better than 72 dB spurious-free dynamic range (SFDR).
  • Best-in-class RF performance with a single sideband (SSB) phase noise -129 dBc/Hz (1 GHz, 10 kHz offset) for better EVM measurements (5G NR EVM less than 1%).
  • Full-band real-time spectrum analysis (RTSA) to capture elusive or transient signals.
  • Fast, accurate signal and spectrum measurements to increase throughput and yield while minimizing cost in 5G manufacturing
