GNSS Positioning Simulator: Should I expect to see a power level increase or decrease on a spectrum analyzer when turning on multiple channels?

  • Measuring power level on Spectrum analyzer
  • Turn on one channel, measure power, add another channel and repeat measurement
  • Simply adding channels into a simulation will not provide accurate power measurements
  • If the channels are in phase then you will observe a higher power level when adding a channel
  • If the channels are out of phase then you will observe a decrease in power when adding a channel
  • If you are trying to ensure that the simulated signals have the correct power level then you should not use a SimGEN scenario
    • Instead follow the relevant power levels sections of the calibration procedure relevant to your simulator - see FAQ10505
