5.1. Connecting the Meter

To connect the Surecom SW-102, connect the output of your transceiver to the "TX" port on the meter. Then, connect your antenna or dummy load to the "ANT" port. Ensure proper adapters or cables are used if your device has different connector types. The device ships with SL16 to SMA-F and SL16 to SMA-M connectors for common applications.

Watch the video below for a visual guide on connecting the SW-102 to your radio and antenna:

5.2. ເປີດເຄື່ອງ

To power on the SW-102, press and hold the ປຸ່ມສີແດງ for 2 seconds. To power off, press and hold the ປຸ່ມສີແດງ ອີກ 2 ວິນາທີ.

6.1. ການວັດແທກ

Once connected and powered on, the SW-102 will display real-time measurements. To measure SWR and power, ensure the meter is in a vertical position and avoid touching the antenna during measurement. Press the PTT (Push-To-Talk) button on your radio to transmit, and the meter will display the VSWR, transmit power, and other relevant data.

Voltage Standing Wave Ratio (VSWR) is an indication of the amount of mismatch between an antenna and the feed line connecting to it. The range of values for VSWR is from 1 to ∞. A VSWR value under 2 is considered suitable for most antenna applications. The antenna can be described as having a good match. So when someone says that the antenna is poorly matched, very often it means that the VSWR value exceeds 2 for a frequency of interest.

6.2. ສະແດງການແນະນໍາ

The LCD display provides comprehensive information at a glance. Key indicators include:

• ສະຖານະຫມໍ້ໄຟ
• ເວລາເຮັດວຽກ
