Protek Handheld Spectrum Analyzer 100KHz~4.4GHz

The Protek A734 handheld spectrum analyzer has been optimized for the convenience of mobility with lightweight (<2Kg), 5.7 inch sunlight readable LCD, long battery life (> 8 hours) and smart battery indicator. 

Comparable DANL (Displayed Average Noise Level) enables users to detect more accurately low level of signals and additional features such as phase noise measurement, audio listen, and zero span options, will lead users to take advantage of Protek A734 in more field applications than other spectrum analyzers.
