The DETECTOR SELECTION menu is displayed
The instrument is equipped with a wide range of detectors for
measuring modulation signals. The peak detectors are a good
choice for capturing the highest positive or negative peak within the
measurement time, while the RMS and Average detectors are the
best choice for measuring noise and residual modulation. The THD
& SINAD detector measure the distortion of the demodulated audio
signal. All detectors can be used in parallel.
In the DETECTOR SELECTION menu press the
DISTORTION &
