The upgraded IPS LCD 4-inch high-definition display and knob design make the operation easier, more sensitive to touch, and more accurate, helping you to read data quickly. The SA5 analyzer has a built-in large-capacity 5000mAh rechargeable battery, providing 10 hours of portable use time, with a Type-c charging cable, no need for frequent charging. [2-in-1 multi-function] SA5 is a compact frequency harmonic analyzer and signal generator with many impressive functions. [Frequency harmonic analyzer] The frequency range is 0.1-800MHZ. After turning on Ultra mode, it provides a signal frequency of up to 5.3GHz that can be calibrated, and can monitor a signal frequency of up to 12GHz. [Signal generator] When not used as a frequency analyzer, it can output a sine wave of 0.1-800MHz, a square wave of up to 4.4GHz, or a RF test signal of up to 5.3GHz. [Switchable resolution bandpass filter] Resolution bandpass filter range from 200Hz to 850kHz. [Optional LNA] Built-in 20dB low noise amplifier (LNA). [Frequency harmonic display] Displays up to 450 points, showing 4 independently configured curves [Storage] Micro-SD card slot for storing measurement data, settings and screenshots. [Input attenuator] Step attenuator adjustable from 0dB to 31dB (cannot be used with LNA) [Calibration]: Built-in calibration signal generator for automatic self-test and input calibration, [PC connection] Connect via USB, function as a PC-controlled frequency harmonic analyzer or signal generator. Convenient data transfer directly to the computer.
