LoRa module LoRa1262 transmit power test

Power is one of the most important parameters of the wireless module. The greater the power of the LoRa module, the farther the transmission distance is, but the higher the power consumption is. Everyone knows the LoRa module is tested for transmit power at the factory. Today, NiceRF tells you how to test the output power of the LoRa module.

NiceRF: LoRa module LoRa1262 transmit power test

1.  Preparation tool

LoRa module LoRa1262

Product function test stand

Spectrum Analyzer

LoRa1262 module test DEMO board

2.  Test process of LoRa module LoRa1262

2.1 Connect the DC power supply to the product test stand, then set the DC power supply voltage to 5V.

2.2 Put the LoRa module LoRa1262 into the fixture of the product function test stand in the correct direction.

2.3 Set the parameters of module in the product function test stand and the DEMO board the same.

2.4 Observe whether the LoRa1262 DEMO board indicator flashes alternately. If it is, it means the communication is successful, go to the next step. if not, it means the communication is unsuccessful, you need to reset the parameters or judge whether the wireless module is good.

2.5 After the communication is successful, observe whether the horizontal line above the spectrum analyzer is greater than the specified qualified value and the two highest points are within the frequency line to be qualified products.

3. Precautions for LoRa module LoRa1262 testing

1. The power connection between the DC power supply and the test fixture cannot be reversed, and the DC power supply voltage cannot be adjusted after setting.

2. The parameters of the spectrum analyzer cannot be changed after the parameter setting is completed.

3. Power supply instruments must be grounded reliably.
