Ultrasonic modulation is realized by superheterodyne, and the reference
frequency of modulation can be set. It is recommended to use the frequency
band of about 38.6kHz for modulation and monitoring.
Focusing
The focusing function is mainly used to eliminate interference noise, reflection
noise, multi-sound source interference, etc. When the test environment is noisy
and the cloud images are numerous, scattered and chaotic, the focusing
function can be enabled. The acoustic cloud images will be focused to a circle
to exclude other interference sources.
Double tap the circle in the middle of main interface to change the test range.
Double tap it again to restore the initial range.
