This transmitter model produces transmissions that use dimensional transmission power (that changes over time and/or frequency) in their analog representation and the configured modulation.

Allowed expressions for time and frequency coordinates in the gains parameters:

  s|c|e
  s|c|e+-quantity
  s|c|e+-b|d
  s|c|e+-b|d+-quantity
  s|c|e+-b|d*number
  s|c|e+-b|d*number+-quantity

where s = start, e = end, c = center frequency, b = bandwidth, d = duration. For example: c-b*0.5-1MHz
