Feature: 1. Spectrum analyzer supports the display of the spectrum, amplitude, and frequency of the signal under test. 2. The instrument uses digital circuits and microprocessors, with storage and calculation functions. 3. Can be used to measure signal distortion, modulation, spectrum purity, frequency stability, and intermodulation distortion. 4. It can be used to measure certain parameters of circuit systems such as amplifiers and filters. 5. Adopts standard interface, and the frequency range is 9kHZ-500.009MHZ, which is convenient for measurement. Specification: Item Type: Spectrum Analyzer Material: ABS Main Function: Display the spectrum, amplitude and frequency of the signal under test. It can be displayed in a panoramic view, or a bandwidth test can be selected.
