Feature:1. Dual Input: 0.1mhz to 350mhz MF HF VHF high quality input, 240mhz to 960mhz low quality UHF input, switchable resolution bandpass filter suitable for two ranges between 2.6khz and 640khz.2. Frequency Range: Using analytical filter can isolate the input power in a small frequency range, the fastest sweep speed is about 2 times per second at rbw or 300khz or wider, and takes about 2 minutes to scan from 0mhz to 350mhz with 10khz rbw.3. 4 Modes: The input and output specifications are divided into 4 modes, low input mode, high input mode, low output mode and high output mode, and the firmware is upgradeable.4. Signal Generator Output: Can be used as a signal generator, the output of sine MF HF VHF is between 0.1mhz to 350mhz, and the output of ultra high frequency square wave is between 240mhz to 960mhz.5. Built in Calibration: The color screen displays 290 sweep points, covering the entire low or high frequency range, built in calibration signal generator for automatic self test and low input calibration.6. PC Control: Can be connected to a computer via USB, can controlled the spectrum analyzer by computer, for Windows driver will be installed automatically, for linux driver is built into the kernel.7. USB Interface: The USB interface implements the serial over usb (cdc) protocol, various commands that can be called through the serial port, which can be used to perform measurements or update internal settings.Specification:Item Type: Spectrum AnalyzerMaterial: ABSScreen: 2.8 inch touch screenBattery: 1 x 306090 3.7V 2000mAh polymer lithium battery (built in).Package List:1 xSpectrum Analyzer2 x Connection Cable1 x Connector1 x Touchscreen Pen1 x Data Cable1 x Antenna Have a great time shopping!
