Noise Density dBm/Hz
Symbolrate kBaud
Power dBm

White cells are outputvalues

Most receivers work between -30dBm to -60dBm

The Noise density should be measured on a spectrum analyzer by:

- Setting bandwidths to ALL AUTO

- Lower the video filtring (video average)

-Use the noise marker to measure the dBm/Hz value on peak of the carrier
