Best Audio Spectrum Analyzers

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

...e 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.
