This is an antenna analyzer for ham radio hobbyists. It can measure 50 ohms source impedance. It is also a meter for measuring SWR・ impedance・ capacitance...

Features:
Test the antenna technical parameters.
Can test the standing wave・ impedance・ capacitance and so on.
Frequency generation & control: 1-60MHz.
External power supply: 2.1mm power jack(center pin positive).
6 operation buttons・ easy and convenient to operate.
Installed black metal case・ just connect the power(not included) and then work.
Step size: user configurable increments of 100Hz・ 1KHz・ 10KHz・ and 100KHz.
Support measuring data waveform analysis via connecting computer with USB cable(not included).
