Measure the power levels with a marker.
Take the first measurement from 250 us after the trigger, the second from 750 us, the third on 1225 us
and so on in every 500 us until the table is filled.
Note:
It must be possible to measure power levels down to –68 dBm. The measured power levels must
be monotonously decreasing.
Make sure that the marker is not measuring the level of noise spike on lower levels.
