N1201SA series is a portable RF vector impedance measurement analyzer, which is easy to use and easy to operate. Built in high capacity lithium-ion battery, suitable for mobile and outdoor use.
The shutdown automatically saves the setting parameters without manual intervention. After the startup, the interface settings are exactly the same as before the power-off, which is very easy to use.
It can be used to test the impedance of antenna and RF equipment.
Because RF impedance measurement needs to be calibrated, you need to purchase calibration separately.

The instrument has four interfaces: single point measurement, scanning, system information, calibration and calibration.
The default guide is to enter the single point measurement interface.

For the convenience of the user, the calibration option for each calibration will be automatically changed to user calibration. At the same time, in order to ensure the integrity of the calibration, during the calibration process, the automatic shutdown function will fail and the guidance will be consistent.

Startup and shutdown:
Press and hold the CTRL key to turn off, and then press the power switch button.
In the start-up state, press and hold the switch button (more than 2S) for a long time. After releasing, the instrument will turn off.
In the start-up state, press and hold the switch button (more than 2S) for a long time. After releasing, the instrument will turn off.

Recommended use:
1. To ensure the accuracy of measurement and calibration, please preheat the instrument for at least 15 minutes.
2. Try to use high-quality RF cable and connector.
3. Calibration cables marked with the next mark may not need to be calibrated and used directly.
4. The process of testing the cable will affect the measurement accuracy. It is recommended not to select too long testing cable when possible.
5. Before measurement and calibration, please make sure you are not in the strong wireless signal to avoid interference due to inaccurate measurement.
6. If the impedance measurement itself is not understood, you can refer to the instructions and tutorials of vector network analyzer. The instrument is equivalent to single port vector network analysis.

Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-3cm measuring deviation due to manual measurement.
