Welcome to our store! 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 areas between 2.6khz and 640khz. 2. Frequency Range: Using an 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 it 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 can be upgraded. 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, the spectrum analyzer can be controlled by computer, for Windows the driver is installed automatically, for Linux the 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 via the serial port, which can be used to perform measurements or update internal settings.
