VENTUS 2.0

RF level : 0dBm, C/N : 0dB, BW : 4MHz

CW Test

CW Example

- Total Power : Constant (RF level = 0dBm)
- C/N : 0dB : Signal Power is equal to Noise Power in 4Mhz BW
- CW level(power and level is same at CW) : -3.4dBm = 0.457mW
- Noise + CW = -0.2dBm @ 4MHz BW : 0.955mW
- Noise = 0.955 – 0.457 = 0.498mW
- Noise power is equal to CW signal
- Small Difference is because of Measurement error and digital numerical quantization error.
