Giới thiệu Máy Phân Tích Cầm Tay USB Type-C 2.8inch Với 4 Chế Độ Chiếu Sáng 100KHz-350MHz Và 260-960MHz

This spectrum analyzer is made of fine quality material, practical, easy to operate and use, has a long service life. With 2.8inch color touching display, and two inputs, MF/HF/VHF input for 0.1MHz-350MHz, and UHF input for 260MHz-960MHz. Totally 4 operation modes design, low input mode, high input mode, low output mode, high output mode, you can adjust according to your demands. You can have a try.



Features:

2.8inch color touching display showing 290 scan points covering up to the full low or high frequency  ranges.

Equipped with two inputs, MF/HF/VHF input for 0.1MHz-350MHz, and UHF input for 260MHz-960MHz.

With switchable resolution bandpass filters for both  rangess between 2.6KHz and 640KHz.

Input step-attenuator from 0dB to 31dB for the MF/HF/VHF input.

It not only can be used as spectrum analyzer but also can be used as signal generator, MF/HF/VHF sinus output between 0.1MHz-350MHz, UHF squarewave output between 260MHz-960MHz.

A built-in calibration signal generator that is used for automatic self test and low input calibration.

Totally 4 operation modes design, low input mode, high input mode, low output mode, high output mode, you can adjust according to your demands.

Connected to a PC via USB it becomes a PC controlled spectrum analyzer.

The built-in USB Type-C rechargeable battery allowing a minimum of at least 2 hours portable use.

Two types optional, you can choose with antenna and without antenna according to your demands.
