Made of fine quality material, practical, easy to operate and use, wide application range, has a long service life. Specifications: Main material: aluminum alloy&#43;metal Color: black Screen size: 4.3 inch Battery: 1 * lithium battery, 2000mAh (included) Spectrum display range: 35M-4400MHz Input impedance: 50 ohms RBW: 100KHz, 200KHz, 500KHz, a total of 5 gear positions can be adjusted Screen scan points: 700 points Scanning span: 7M (10KHz), 35M (50KHz), 70M (100KHz), 140M (200KHz), 350M (500KHz) dBm range: -80dB~10dB (support manual adjustment of calibration amplitude), the unit does not have an amplifier circuit inside, if you need to measure small signals, you need an external amplifier. Maximum access signal: 10dB Working mode: superheterodyne scanning spectrum analyzer, single scan time is 800ms Item size: 145 * 70 * 30mm / 5.7 * 2.8 * 1.2in Item weight: 200g / 7.1ounce Package size: 300 * 140 * 70mm / 11.8 * 5.5 * 2.8in Package weight: 335g / 11.8ounce Note: This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high accuracy VCO source, the heterodyne signal frequency can be measured very accurately. Since the scanning range is very large (35M-4400M), because there is no special detection circuit for the external measurement signal due to cost and other factors, the measurement amplitude may have errors. Therefore, the product increases the magnification and displacement parameters, and the user can adjust the display waveform by himself. The amplitude display is adjusted and calibrated. Packing List: 1 * Handheld Simple Spectrum Analyzer
