Portable tinySA Spectrum Analyzer - AURSINC Hand Held Frequency Analyzer 2021 Upgraded V0.3.1 | 100kHz to 960MHz MF/HF/VHF UHF Input | ESD Protected Function & 2.8 inch Touchscreen | Signal Generator

  • ...are installed which will be more stable and sensitive with higher antistatic level and longer service life. Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz.
  • [Frequency Range] Spectrum analyzers like the tinySA use a resolution filter that is used to isolate the input power in a small frequency range. This resolution filter is swept across the desired frequency range. The fastest scanning speed occurs with an RBW or 300kHz or wider and is about 2 scans per second. But with increase of the frequency span and decrease of the RBW the scanning speed decreases quickly. A scan from 0MHz to 350MHz with an RBW of 10kHz takes about 2 minutes..
  • [2 in 1 Device] When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Built-in calibration signal generator that is used for automatic self test and low input calibration. The tinySA contains all the components of a conventional heterodyne swept spectrum analyzer. Color display showing 290 scan points covering up to the full low or high frequency range.

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

  • 2023 NEWEST TINYSA: Produced by Hugen, AURSINC ULTRA Tinysa owns high performance frequency in 100khz to 800MHz, and when in ultra mode, the analyzer can reach 5.3GHz. With new 4” touchscreen display and installed with the latest hardware system V0.4.5.1. tinysa is more professional, stable, sensitive and easy to be operated.
  • A Lab-grade Spectrum Analyzer: The ultra-wide range frequency 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 ....
