TinySA Ultra+ ZS406 Spectrum Analyzer

[CTS Admin]

I picked one of these on Amazon and love it. You talk about powerful and compact, this is it. You no longer need a spectrum analyzer that costs 10's of thousands.

The one I picked up was ,...

• tinySA Ultra+ ZS406
  • Spectrum Analyzer for 0.1-900MHz or, with Ultra mode enabled up to 5.3 GHz, level calibrated up to 6GHz. Can observe signals up to 12GHz
  • Signal Generator with sine wave output between 0.1-900MHz or square wave up to 4.4GHz or rf test signal output up to 5.4GHz when not used as Spectrum Analyzer.
  • Other spec same specs as ZS405

I have only used it to check for spurious emissions on my Baofeng and QRZ handhelds as I haven't had it very long. But I plan to do some experimentation with its abilities. As a note, the Baofeng had spurious emissions that did not conform to FCC regulations. The QRZ passed with flying colors.
