RFLink.ComputeLinkMargin(TimeSpan, String, Variable, Variable) Method

Top

Description

Returns the link margin for the link based on the calculated energy per bit to noise power spectral density ratio (Eb/No) and the required energy per bit to noise power spectral density ratio (Eb/No) as determined by the input and inputType arguments. Returns the results in units of dB.
