N1201SA RF Vector Impedance Analyzer ANT SWR Antenna Meter Tester 137.5-2700MHz Resistance/Impedance/SWR

Features:
This instrument has 4 basic operational interface: single point measurement, scan function, power meter measurement, system information, corrrection and calibration.
The default boot into single-point measurement interface.
High resolution, with calibration function, accurate measurement, and with cost effective.
N1201SA series is the handheld radio frequency vector impedance measurement analysis instrument, easy to use, simple operation.
Built-in high capacity 4.2V, 2000mAh polymer lithium cell, for mobile and outdoor use, provices continuous working time more than 4 hours.
Shutdown automatically save settings parameter without human intervention, after starting up, interface settings completely the same as the power off before, use very convenient.
Can be used to test the antenna, the imppedance of the radio frequency devices.
As RF impedance measuring need calibration, so you need to purchae separately calibration.
Startup and shutdown:
Hold down the CTRL key off press the power switch button to turn on.
The boot state, long press (2S above) the switch button, after the release, the instrument will shut down.
