RF power, typically measured in milliwatts, refers to the strenght of the RF signal. Higher power cover greater distance and penetrate obstacles more effectively.
Purpose:
Transmitter power measurement could be for:
- Transmitter characterization
- Transmitter benchmrak (comparaison)
- Transmitter troubleshooting
- Range communication calculation
- ....
Key Definition:
Signal power is a key parameter for communication transmitters. It refers to the power carried by transmitter signal. Usually, RF power is expressed in "dBm", decibels relative to one milliwatt, and is measured at a defined frequency.
Which ONDUINO to use ?
- Shield reference: RF RANGE
- Functionality: Power Detector
What about test configuration ?
 |
ONDUINO Shield : RF RANGE. |
 |
DUT : Transmitter to measure its RF power. |
 |
RF Cables : Used for connecting transmitter to concerned ONDUINO Shield. |
Notes :
- DUT stands for Device Under Test
How to use it ?
- Plug your shield on one of its compatible Arduino platforms.
- Connect concerned platform to your computer using the appropriate USB cable.
- Download ONDUINO shield Firmware from our website and program your Arduino plateform.
- Download ONDUINO Software from our website and launch it.
- Using ONDUINO Software ( Shield Manual available from conerned menu ), set shield in power detector mode.
- Adjust power detector mode settings if needed, launch your transmitter and start power mesurements.rate expected.
Transmitter power could be read directly from software interface.
Notes:
- In case of expected RF power exceed maximum shield power input, an external attenuator could be used to lower signal intensity. To read real power, introduced attenuation offset should be settled in calibration Software interface ( Shield Manual available from conerned menu ).
