Feature: 1. Real-time spectrum analysis function, support real-time spectrum scanning, SPAN/RBW/CENT/MARKER function, MAXHLOD function, maximum power automatic detection. 2. Stable performance, high detection accuracy, detection frequency range 240-960MHz, can detect real-time spectrum, frequency chromatogram, spectrum thermogram and so on in the frequency band. 3. Small in size, compact structure, easy to carry, very suitable for outdoor field measurement. 4. Built-in lithium batteries can be charged by standard 5V charger of mobile phone. It can be used for about 9 hours at full power. 5. The function of frequency chromatogram shows the whole time and spectrum characteristics in a period of time. It can record all the spectrum distribution in 5 minutes, which is convenient for viewing the frequency interference or emission leakage. 6. Spectrum thermogram function shows overlapping density of spectrum contours over a period of time, and more repetitions tend to be red, which facilitates the analysis of spectrum statistical characteristics over a period of time. 7. In the application of radio frequency testing, wireless optimization, field network layout, interference query, etc., spectrum analyzer is often needed to test the spectrum distribution of signals.
