2023 AURSINC Ultra TinySA 4” Spectrum Analyzer – Portable V0.4.5.1 100kHz-5.3GHz Frequency Analyzer | Built-in 3000mAh Battery & 32GB SD Card | RBW LNA DANL Phase Noise RF Signal Generator

  • ... can reach around 6GHz, together with the excellence of phase noise [email protected], DANL -166dBm/Hz.
  • In Ultra mode the input low pass filter is automatically enabled for all frequencies within the pass-band of the low pass filter (up to 750MHz). For higher frequencies the low pass filter will be bypassed and the measurement will be slower due to the multiple measurements per frequency required for the mirror and spur elimination algorithm.
  • Differences to the Former TinySa: The first big one is that now the default maximum frequency is 800mhz, so you no longer have to switch between low and high range,and can monitor the complete range in one sweep.
  • Second,In the level menu, there is the LNA, which will provide 20db of extra gain if you have very low level signal.
  • Lastly, RBW frequency from 200hz to 850khz which can be set to match the measurement requirements, meet SBB two-tone test requirements and fast scanning.
  • 2 in 1 Device: When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 100kHZ-800MHz, UHF square wave output between 800mHz-4.4GHz, Mixing signal output is between 4.4GHz-5.4GHz.
  • Built-in calibration signal generator that is used for automatic self test and low input calibration. The ultra tiny....
