Spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal distortion, modulation system, spectrum purity, frequency stability and intermodulation distortion.
1, limited protection: the highest input RF level and permanent damage caused by the highest voltage value: DC 25V, AC peak 100V.
2, preheat: test must wait until OVER COLD disappears.
3, since school: use three months, or important measurements before school.
4, system measurement configuration: configuration is to measure before the measurement of some parameters entered, eliminating the need for each measurement once a parameter input.
