Introduction : As we know wireless industry is moving towards 6G research, automotive radar (77 to 81 GHz) and D-band communications (110 to 170 GHz), traditional swept tuned spectrum analyzers are not sufficient. To capture transient, frequency hopping or wideband signals, engineers require a Real Time Spectrum Analyzer (RTSA). This application note explores the requirements for high frequency signal analysis and highlights the Spectran V6 from Aaronia AG, a device currently setting the mobile benchmark for integrated 140 GHz analysis.

Aaronia AG Spectran V6 Real Time Spectrum Analyzer

The Spectran A6 stands out to be RTSA tablet capable of supporting 140 GHz in portable form factor. Unlike benchtop units which require external harmonic mixers and wiring, V6 integrates all these capabilities into a single mobile platform.

Key features

  • Covers 9 KHz to (8 / 18/ 55/ 140 GHz) frequency range
  • Supports 2 x 490 MHz Real Time Bandwidth
  • Supports sweep speed of 1 THz/second and more
  • Equipped with 16 bit ADC and noise floor of - 170 dBm/Hz
  • It also includes an optional signal generator which allows full stimulus response test parameters such as S-parameters, cable loss, etc.
  • Houses built-in AMD 8-Core Ryzen processor with 64GB of RAM

Anritsu CorporationField Master Pro MS2090A : Supports up to 54 GHz, can extends to higher bands using external mixers. Preferred for ruggedized handheld use in traditional 5G FR2 environments.
TektronixRSA7100B : Focused on ultra wideband real time analysis (up to 800 MHz RTBW), though generally requiring frequency converters to reach the 140 GHz range. Best for Focused on ultra-wideband rea time analysis (up to 800 MHz RTBW), though generally requiring frequency converters to reach the 140 GHz range. Best for recording massive amounts of signal data for electronic warfare (EW) analysis.

Conclusion

For engineers requiring the portability of a tablet without sacrificing the “real time” requirements of the 140 GHz frontier, the Aaronia Spectran V6 offers a unique combination of sweep speed, RTBW and integrated high frequency coverage. The benchtop leaders such as Keysight and Rohde & Schwarz remain as manufacturers for laboratory grade phase noise analysis tools.
