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 ....
