4.3 Spectrum Analyzer Function

The device operates as a spectrum analyzer with a frequency range of 100kHz to 5.4GHz. In Ultra mode, it extends up to 6GHz. Key features include:

• Resolution Bandwidth (RBW): Switchable from 200Hz to 850kHz for precise or fast measurements. A 200Hz minimum RBW supports SSB two-tone intermodulation testing.
• Input Attenuator: Includes a 0-31dB input step attenuator.
• Low Noise Amplifier (LNA): An integrated LNA provides 20dB of extra gain for low-level signals (effective below 3.5GHz).
• Phase Noise Performance: -108dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset (at 30MHz).
• Displayed Points: Displays up to 450 points for gapless full-band coverage.

4.4 Signal Generator Function

The TinySA Ultra+ ZS406 also functions as a signal generator:

• MF/HF/VHF Sine Waves: Outputs from 100kHz to 900MHz.
• UHF Square Waves: Outputs from 800MHz to 4.4GHz.
• Mixed Signals: Outputs from 4.4GHz to 5.4GHz.
