Hello Mattia,
For the sweep measurement, only avg/max detectors are available. The QP measurements are relegated to single frequency measurements only. The workflow would ideally be, using a peak detector, finding all frequencies that exceed your limit, then testing those frequencies separately using the QP detector, one frequency at a time. In theory the reading from a peak detector will always be equal/greater than a QP detector. You’re saying you are seeing a larger value from the QP measurement than the peak detector. It might be the sweep isn’t dwelling long enough to characterise the signal. The dwell time can be modified on the sweep to help with this in the range table.
