N2201SS RF Vector Impedance Analyzer ANT SWR Antenna Meter Tester 137.5-2700MHz Resistance/Impedance/SWR

This product is a portable antenna tester, RF device impedance, and board impendance. Compact size and easy to carry, perfect for outdoor and high-altitude special operations. With single point measurement, scan function, power meter measurement, system information, corrrection and calibration function. High resolution, with calibration function, accurate measurement, and with cost effective. You can have a try.

Features:
This instrument's basic functions: 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.
It is for small power and micro power communicatin device testing.
If you use it on large power machine, you need additional coupler or attenuator.  
Built-in 4.2V, 2000mAh polymer lithium cell, continuous working time more than 4 hours.
Note: For the convenience of the user, each time calibration correction options will automatically change to the user calibration.
Meanwhile, in order to ensure the integrity of the calibration, the calibration process, the automatic shutdown function fails, the consistent boot.

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.
 
Recommend the use: 
In order to ensure the accuracy of measurement and calibration, preheat the instrument at least 15 minutes.
Try to use fine quality RF cable and connectors.
Calibrated cable marked to the next may not need to calibrate and direct use.
Test cable process affect the measurement accuracy, it is recommended that, where possible, do not choose too long test cable.
Measurement and calibration before, make sure you are not in a strong wireless signal, so as to avoids interference caused by inaccurate measurements.
If the impedance measurements themselves do not understand, you can refer to a vector network analyzer instructions and tutorials.
This instrument is equivalent to a single-port vector network analysis.
