Frequency range: 9KHz-1.6GHz (tunable to 9KHz) AC Coupled; Optimal sensitivity: -161dBm RBW:10Hz to 1MHz;IP-51 High protection portable design, sturdy and durable, can be used in laboratory, more suitable for field mobile use. HSA2016A spectrum analyzer has the lowest DANL and SSB phase noise, and narrowest RBW. It greatly enhances the recognition ability to the spurious signal and noise signal;Optional FM/AM modulation analysis, including carrier power, modulation rate, AM depth/FM deviation, SINAD and carrier frequency offset. Standard spectrum feature. It can analyze the signal time stability, and find out lacunar signal in communication system accurately;Strong field strength test function, fit for the test work in transmitter, base station and the antenna coverage site. It can show the density of field strength or power. The user could also calibrate gain or loss by using amplitude offset function. The 5.7 inch highlight color display can provide accurate, bright and clear trace both inside and outside, no need to move to shading place for work; Short scanning time. It can fast catch the data and help to locate and recognize the irregular transient disturbance signal, and then optimize the testing time and accuracy. Integration USB Host & Device, support USB flash disk memory, optional WIFI/LAN, which is convenient for networking and long-range control; Its PC software can achieve the management and storage of testing data.
