​The screen size has been upgraded to a 4-inch, clear-definition screen for easier access and use. 
This spectrum analyzer is designed to operate in the 0.1-800MHz wide ranges. 
Support for Ultra-mode, which extends its ranges of application to 0.1MHz-6GHz. 
With 100k-800MHz sinewaves output, 800MHz-4.4GHz squarewaves output, and 4.4GHz-5.4GHz mixed signal output when it is not used as a spectrum analyzer. 
Bandpass filters with the variable resolution are used for both ranges between 200Hz and 850kHz. 
200Hz-850kHz RBW, RBW is down to 200Hz for the efficient splitting of neighboring signals for SSB two-tone intermodulation testing, and up to 850kHz RBW support for fast scanning. 
Input step attenuator from 0dB to 31dB (not combined with LNA). 
A built-in calibration signal generator that is used for automatic self-test and (low) input calibration. 
It can be connected to a PC via USB to make it a PC-controlled spectrum analyzer or signal generator. 
Built-in 3,000mAh rechargeable battery for at least 2 hours of use. 
Maximum input level +10dBm (please note, exceeding this value will damage the unit). 
A built-in 32GB memory card is available to save measurement data and screenshots.​
