The power level indicated by the MiniTioune or Portsdown software when using a MiniTiouner is only indicative. The measurement bandwidth (3dB) is about 10 MHz, regardless of the received SR, and so it is useless for peaking received signal strength. However, it should be used to check that the tuner is receiving enough signal, but not too much.

Measurements of the received power indication were made using MiniTioune Version v0.9beta8_9 while receiving the QO-100 beacon. A line amplifier and a switched attenuator were used to accurately input a wide range of power levels. Using the same test set-up similar measurements were made using modified LongMynd software to support developement of input level indication on the Portsdown.

The results are tabulated below.
