Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...99Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions.
